BGE logic update: new servo control motion actuator, new distance constraint actuator, new orientation constraint actuator, new actuator sensor. General ======= - Removal of Damp option in motion actuator (replaced by Servo control motion). - No PyDoc at present, will be added soon. Generalization of the Lvl option ================================ A sensor with the Lvl option selected will always produce an event at the start of the game or when entering a state or at object creation. The event will be positive or negative depending of the sensor condition. A negative pulse makes sense when used with a NAND controller: it will be converted into an actuator activation. Servo control motion ==================== A new variant of the motion actuator allows to control speed with force. The control if of type "PID" (Propotional, Integral, Derivate): the force is automatically adapted to achieve the target speed. All the parameters of the servo controller are configurable. The result is a great variety of motion style: anysotropic friction, flying, sliding, pseudo Dloc... This actuator should be used in preference to Dloc and LinV as it produces more fluid movements and avoids the collision problem with Dloc. LinV : target speed as (X,Y,Z) vector in local or world coordinates (mostly useful in local coordinates). Limit: the force can be limited along each axis (in the same coordinates of LinV). No limitation means that the force will grow as large as necessary to achieve the target speed along that axis. Set a max value to limit the accelaration along an axis (slow start) and set a min value (negative) to limit the brake force. P: Proportional coefficient of servo controller, don't set directly unless you know what you're doing. I: Integral coefficient of servo controller. Use low value (<0.1) for slow reaction (sliding), high values (>0.5) for hard control. The P coefficient will be automatically set to 60 times the I coefficient (a reasonable value). D: Derivate coefficient. Leave to 0 unless you know what you're doing. High values create instability. Notes: - This actuator works perfectly in zero friction environment: the PID controller will simulate friction by applying force as needed. - This actuator is compatible with simple Drot motion actuator but not with LinV and Dloc motion. - (0,0,0) is a valid target speed. - All parameters are accessible through Python. Distance constraint actuator ============================ A new variant of the constraint actuator allows to set the distance and orientation relative to a surface. The controller uses a ray to detect the surface (or any object) and adapt the distance and orientation parallel to the surface. Damp: Time constant (in nb of frames) of distance and orientation control. Dist: Select to enable distance control and set target distance. The object will be position at the given distance of surface along the ray direction. Direction: chose a local axis as the ray direction. Range: length of ray. Objecgt within this distance will be detected. N : Select to enable orientation control. The actuator will change the orientation and the location of the object so that it is parallel to the surface at the vertical of the point of contact of the ray. M/P : Select to enable material detection. Default is property detection. Property/Material: name of property/material that the target of ray must have to be detected. If not set, property/ material filter is disabled and any collisioning object within range will be detected. PER : Select to enable persistent operation. Normally the actuator disables itself automatically if the ray does not reach a valid target. time : Maximum activation time of actuator. 0 : unlimited. >0: number of frames before automatic deactivation. rotDamp: Time constant (in nb of frame) of orientation control. 0 : use Damp parameter. >0: use a different time constant for orientation. Notes: - If neither N nor Dist options are set, the actuator does not change the position and orientation of the object; it works as a ray sensor. - The ray has no "X-ray" capability: if the first object hit does not have the required property/material, it returns no hit and the actuator disables itself unless PER option is enabled. - This actuator changes the position and orientation but not the speed of the object. This has an important implication in a gravity environment: the gravity will cause the speed to increase although the object seems to stay still (it is repositioned at each frame). The gravity must be compensated in one way or another. the new servo control motion actuator is the simplest way: set the target speed along the ray axis to 0 and the servo control will automatically compensate the gravity. - This actuator changes the orientation of the object and will conflict with Drot motion unless it is placed BEFORE the Drot motion actuator (the order of actuator is important) - All parameters are accessible through Python. Orientation constraint ====================== A new variant of the constraint actuator allows to align an object axis along a global direction. Damp : Time constant (in nb of frames) of orientation control. X,Y,Z: Global coordinates of reference direction. time : Maximum activation time of actuator. 0 : unlimited. >0: number of frames before automatic deactivation. Notes: - (X,Y,Z) = (0,0,0) is not a valid direction - This actuator changes the orientation of the object and will conflict with Drot motion unless it is placed BEFORE the Drot motion actuator (the order of actuator is important). - This actuator doesn't change the location and speed. It is compatible with gravity. - All parameters are accessible through Python. Actuator sensor =============== This sensor detects the activation and deactivation of actuators of the same object. The sensor generates a positive pulse when the corresponding sensor is activated and a negative pulse when it is deactivated (the contrary if the Inv option is selected). This is mostly useful to chain actions and to detect the loss of contact of the distance motion actuator. Notes: - Actuators are disabled at the start of the game; if you want to detect the On-Off transition of an actuator after it has been activated at least once, unselect the Lvl and Inv options and use a NAND controller. - Some actuators deactivates themselves immediately after being activated. The sensor detects this situation as an On-Off transition. - The actuator name can be set through Python.

BGE patch: DUPLIGROUP option supported in BGE. Blender duplicates groups in the 3D view at the location of objects having the DUPLIGROUP option set. This feature is now supported in the BGE: the groups will be instantiated as in the 3D view when the scene is converted. This is useful to populate a scene with multiple enemies without having to actually duplicate the objects in the blend file. Notes: * The BGE applies the same criteria to instantiate the group as Blender to display them: if you see the group in the 3D view, it will be instantiated in the BGE. * Groups are instantiated as if the object having the DUPLIGROUP option (usually an empty) executed an AddObject actuator on the top objects of the group (objects without parent). * As a result, only intra-group parent relationship is supported: the BGE will not instantiate objects that have parents outside the group. * Intra-group logic bricks connections are preserved between the duplicated objects, even between the top objects of the group. * For best result, the state engine of the objects in the group should be self-contained: logic bricks should only have intra-group connections. Use messages to communicate with state engines outside the group. * Nested groups are supported: if one or more objects in the group have the DUPLIGROUP option set, the corresponding groups will be instantiated at the corresponding position and orientation. * Nested groups are instantiated as separate groups, not as one big group. * Linked groups are supported as well as groups containing objects from the active layers. * There is a difference in the way Blender displays the groups in the 3D view and how BGE instantiates them: Blender does not take into account the parent relationship in the group and displays the objects as if they were all children of the object having the DUPLIGROUP option. That's correct for the top objects of the group but not for the children. Hence the orientation of the children objects may be different in the BGE. * An AddGroup actuator will be added in a future release.

Patch: [ #2439 ] Makes objects react properly to deformations after a mesh replacement call. from brian hayward (bthayward) Detailed description: Currently, when an armature deformed object's mesh is replaced by the ReplaceMesh actuator, the new mesh fails to deform to the armature's movement. My patch fixes this by properly replacing the deform controller along with the mesh (when appropriete). For instance, if one had an animated character using any of the standard deformation techniques (armature, ipo, RVK, or AVK), that character's mesh would currently be prevented from changing mid-game. It could be replaced, but the new mesh would lack the controller which tells it how to deform. If one wanted to dynamiclly add a hat on top of the character's head, it would require storing a secondary prebuilt character (mesh, armature, logic, ect...) on another layer FOR EACH HAT the character could possibly wear, then swapping out the whole character when the hat change was desired. So if you had 4 possible hat/character combos, you would have 4 character meshes, 4 armatures, 4 sets of logic, and so on. I find this lack of flexibility to be unresonable. With my patch, one could accomplish the same thing mearly by making one version of the character in the main layer, and adding an invisible object atop the character's head (which is parented to the head bone). Then whenever it becomes desirable, one can replace the invisible object's mesh with the desirable hat's mesh, then make it visible. With my patch, the hat object would then continue to deform to the character's head regardless of which hat was currently being worn. *note 1* for armature/mesh deformations, the new mesh must have properly assigned vertex groups which match one or more of the bones of the target armature before the replaceMesh call is made. Otherwise the vertices won't react to the armature because they won't know how. (not sure if vertices can be scripted to change groups after the game has started) *note 2* The added processing time involved with replacing the object's deform controller is negligible.

Patch:[#25163] BGE support for Blender Font objects - unicode support Problem/Bug: ------------ There were no way to have proper unicode characters (e.g. Japanese) in Blender Game Engine. Now we can :) You can see a sample here: http://blog.mikepan.com/multi-language-support-in-blender/ Functionality Explanation: -------------------------- This patch converts the Blender Font Objects to a new BGE type: KX_FontObject This object inherits KX_GameObject.cpp and has the following properties: - text (the text of the object) - size (taken from the Blender object, usually is 1.0) - resolution (1.0 by default, maybe not really needed, but at least for debugging/the time being it's nice to have) The way we deal with linked objects is different than Blender. In Blender the text and size are a property of the Text databock. Therefore linked objects necessarily share the same text (and size, although the size of the object datablock affects that too). In BGE they are stored and accessed per object. Without that it would be problematic to have addObject adding texts that don't share the same data. Known problems/limitations/ToDo: -------------------------------- 1) support for packed font and the <builtin> 2) figure why some fonts are displayed in a different size in 3DView/BGE (BLF) 3) investigate some glitches I see some times 4) support for multiline 5) support for more Blender Font Object options (text aligment, text boxes, ...) [1] Diego (bdiego) evantually will help on that. For the time being we are using the "default" (ui) font to replace the <builtin>. [2] but not all of them. I need to cross check who is calculating the size/dpi in/correctly - Blender or BLF. (e.g. fonts that work well - MS Gothic) [3] I think this may be related to the resolution we are drawing the font [4] It can't/will not be handled inside BFL. So the way I see it is to implement a mini text library/api that works as a middlelayer between the drawing step and BLF. So instead of: BLF_draw(fontid, (char *)text, strlen(text)); We would do: MAGIC_ROUTINE_IM_NOT_BLF_draw(fontir, (char *)text, styleflag, width, height); [5] don't hold your breath ... but if someone wants to have fun in the holidays the (4) and (5) are part of the same problem. Code Explanation: ----------------- The patch should be simple to read. They are three may parts: 1) BL_BlenderDataConversion.cpp:: converts the OB_FONT object into a KX_FontObject.cpp and store it in the KX_Scene->m_fonts 2) KetsjiEngine.cpp::RenderFonts:: loop through the texts and call their internal drawing routine. 3) KX_FontObject.cpp:: a) constructor: load the font of the object, and store other values. b) DrawText: calculate the aspect for the given size (sounds hacky but this is how blf works) and call the render routine in RenderTools 4) KX_BlenderGL.cpp (called from rendertools) ::BL_print_game_line:: Draws the text. Using the BLF API *) In order to handle visibility of the object added with AddObject I'm adding to the m_scene.m_fonts list only the Fonts in a visible layer - unlike Cameras and Lamps where all the objects are added. Acknowledgements: ---------------- Thanks Benoit for the review and adjustment suggestions. Thanks Diego for the BFL expertise, patches and support (Latin community ftw) Thanks my boss for letting me do part of this patch during work time. Good thing we are starting a project in a partnership with a Japanese Foundation and eventual will need unicode in BGE :) for more details on that - www.nereusprogram.org - let's call it the main sponsor of this "bug feature" ;)

BGE logic patch: new "Add" mode for Ipo actuator, several corrections in state system. New Add mode for Ipo actuator ============================= A new Add button, mutually exclusive with Force button, is available in the Ipo actuator. When selected, it activates the Add mode that consists in adding the Ipo curve to the current object situation in world coordinates, or parent coordinates if the object has a parent. Scale Ipo curves are multiplied instead of added to the object current scale. If the local flag is selected, the Ipo curve is added (multiplied) in the object's local coordinates. Delta Ipo curves are handled identically to normal Ipo curve and there is no need to work with Delta Ipo curves provided that you make sure that the Ipo curve starts from origin. Origin means location 0 for Location Ipo curve, rotation 0 for Rotation Ipo curve and scale 1 for Scale Ipo curve. The "current object situation" means the object's location, rotation and scale at the start of the Ipo curve. For Loop Stop and Loop End Ipo actuators, this means at the start of each loop. This initial state is used as a base during the execution of the Ipo Curve but when the Ipo curve is restarted (later or immediately in case of Loop mode), the object current situation at that time is used as the new base. For reference, here is the exact operation of the Add mode for each type of Ipo curve (oLoc, oRot, oScale, oMat: object's loc/rot/scale and orientation matrix at the start of the curve; iLoc, iRot, iScale, iMat: Ipo curve loc/rot/scale and orientation matrix resulting from the rotation). Location Local=false: newLoc = oLoc+iLoc Local=true : newLoc = oLoc+oScale*(oMat*iLoc) Rotation Local=false: newMat = iMat*oMat Local=true : newMat = oMat*iMat Scale Local=false: newScale = oScale*iScale Local=true : newScale = oScale*iScale Add+Local mode is very useful to have dynamic object executing complex movement relative to their current location/orientation. Of cource, dynamics should be disabled during the execution of the curve. Several corrections in state system =================================== - Object initial state is taken into account when adding object dynamically - Fix bug with link count when adding object dynamically - Fix false on-off detection for Actuator sensor when actuator is trigged on negative event. - Fix Parent actuator false activation on negative event - Loop Ipo curve not restarting at correct frame when start frame is different from one.

BGE patch: DUPLIGROUP option supported in BGE. Blender duplicates groups in the 3D view at the location of objects having the DUPLIGROUP option set. This feature is now supported in the BGE: the groups will be instantiated as in the 3D view when the scene is converted. This is useful to populate a scene with multiple enemies without having to actually duplicate the objects in the blend file. Notes: * The BGE applies the same criteria to instantiate the group as Blender to display them: if you see the group in the 3D view, it will be instantiated in the BGE. * Groups are instantiated as if the object having the DUPLIGROUP option (usually an empty) executed an AddObject actuator on the top objects of the group (objects without parent). * As a result, only intra-group parent relationship is supported: the BGE will not instantiate objects that have parents outside the group. * Intra-group logic bricks connections are preserved between the duplicated objects, even between the top objects of the group. * For best result, the state engine of the objects in the group should be self-contained: logic bricks should only have intra-group connections. Use messages to communicate with state engines outside the group. * Nested groups are supported: if one or more objects in the group have the DUPLIGROUP option set, the corresponding groups will be instantiated at the corresponding position and orientation. * Nested groups are instantiated as separate groups, not as one big group. * Linked groups are supported as well as groups containing objects from the active layers. * There is a difference in the way Blender displays the groups in the 3D view and how BGE instantiates them: Blender does not take into account the parent relationship in the group and displays the objects as if they were all children of the object having the DUPLIGROUP option. That's correct for the top objects of the group but not for the children. Hence the orientation of the children objects may be different in the BGE. * An AddGroup actuator will be added in a future release.

Patch:[#25163] BGE support for Blender Font objects - unicode support Problem/Bug: ------------ There were no way to have proper unicode characters (e.g. Japanese) in Blender Game Engine. Now we can :) You can see a sample here: http://blog.mikepan.com/multi-language-support-in-blender/ Functionality Explanation: -------------------------- This patch converts the Blender Font Objects to a new BGE type: KX_FontObject This object inherits KX_GameObject.cpp and has the following properties: - text (the text of the object) - size (taken from the Blender object, usually is 1.0) - resolution (1.0 by default, maybe not really needed, but at least for debugging/the time being it's nice to have) The way we deal with linked objects is different than Blender. In Blender the text and size are a property of the Text databock. Therefore linked objects necessarily share the same text (and size, although the size of the object datablock affects that too). In BGE they are stored and accessed per object. Without that it would be problematic to have addObject adding texts that don't share the same data. Known problems/limitations/ToDo: -------------------------------- 1) support for packed font and the <builtin> 2) figure why some fonts are displayed in a different size in 3DView/BGE (BLF) 3) investigate some glitches I see some times 4) support for multiline 5) support for more Blender Font Object options (text aligment, text boxes, ...) [1] Diego (bdiego) evantually will help on that. For the time being we are using the "default" (ui) font to replace the <builtin>. [2] but not all of them. I need to cross check who is calculating the size/dpi in/correctly - Blender or BLF. (e.g. fonts that work well - MS Gothic) [3] I think this may be related to the resolution we are drawing the font [4] It can't/will not be handled inside BFL. So the way I see it is to implement a mini text library/api that works as a middlelayer between the drawing step and BLF. So instead of: BLF_draw(fontid, (char *)text, strlen(text)); We would do: MAGIC_ROUTINE_IM_NOT_BLF_draw(fontir, (char *)text, styleflag, width, height); [5] don't hold your breath ... but if someone wants to have fun in the holidays the (4) and (5) are part of the same problem. Code Explanation: ----------------- The patch should be simple to read. They are three may parts: 1) BL_BlenderDataConversion.cpp:: converts the OB_FONT object into a KX_FontObject.cpp and store it in the KX_Scene->m_fonts 2) KetsjiEngine.cpp::RenderFonts:: loop through the texts and call their internal drawing routine. 3) KX_FontObject.cpp:: a) constructor: load the font of the object, and store other values. b) DrawText: calculate the aspect for the given size (sounds hacky but this is how blf works) and call the render routine in RenderTools 4) KX_BlenderGL.cpp (called from rendertools) ::BL_print_game_line:: Draws the text. Using the BLF API *) In order to handle visibility of the object added with AddObject I'm adding to the m_scene.m_fonts list only the Fonts in a visible layer - unlike Cameras and Lamps where all the objects are added. Acknowledgements: ---------------- Thanks Benoit for the review and adjustment suggestions. Thanks Diego for the BFL expertise, patches and support (Latin community ftw) Thanks my boss for letting me do part of this patch during work time. Good thing we are starting a project in a partnership with a Japanese Foundation and eventual will need unicode in BGE :) for more details on that - www.nereusprogram.org - let's call it the main sponsor of this "bug feature" ;)

Patch: [ #2439 ] Makes objects react properly to deformations after a mesh replacement call. from brian hayward (bthayward) Detailed description: Currently, when an armature deformed object's mesh is replaced by the ReplaceMesh actuator, the new mesh fails to deform to the armature's movement. My patch fixes this by properly replacing the deform controller along with the mesh (when appropriete). For instance, if one had an animated character using any of the standard deformation techniques (armature, ipo, RVK, or AVK), that character's mesh would currently be prevented from changing mid-game. It could be replaced, but the new mesh would lack the controller which tells it how to deform. If one wanted to dynamiclly add a hat on top of the character's head, it would require storing a secondary prebuilt character (mesh, armature, logic, ect...) on another layer FOR EACH HAT the character could possibly wear, then swapping out the whole character when the hat change was desired. So if you had 4 possible hat/character combos, you would have 4 character meshes, 4 armatures, 4 sets of logic, and so on. I find this lack of flexibility to be unresonable. With my patch, one could accomplish the same thing mearly by making one version of the character in the main layer, and adding an invisible object atop the character's head (which is parented to the head bone). Then whenever it becomes desirable, one can replace the invisible object's mesh with the desirable hat's mesh, then make it visible. With my patch, the hat object would then continue to deform to the character's head regardless of which hat was currently being worn. *note 1* for armature/mesh deformations, the new mesh must have properly assigned vertex groups which match one or more of the bones of the target armature before the replaceMesh call is made. Otherwise the vertices won't react to the armature because they won't know how. (not sure if vertices can be scripted to change groups after the game has started) *note 2* The added processing time involved with replacing the object's deform controller is negligible.

Known problems/limitations/ToDo: -------------------------------- 1) support for packed font and the <builtin> 2) figure why some fonts are displayed in a different size in 3DView/BGE (BLF) 3) investigate some glitches I see some times 4) support for multiline 5) support for more Blender Font Object options (text aligment, text boxes, ...) [1] Diego (bdiego) evantually will help on that. For the time being we are using the "default" (ui) font to replace the <builtin>. [2] but not all of them. I need to cross check who is calculating the size/dpi in/correctly - Blender or BLF. (e.g. fonts that work well - MS Gothic) [3] I think this may be related to the resolution we are drawing the font [4] It can't/will not be handled inside BFL. So the way I see it is to implement a mini text library/api that works as a middlelayer between the drawing step and BLF. So instead of: BLF_draw(fontid, (char *)text, strlen(text)); We would do: MAGIC_ROUTINE_IM_NOT_BLF_draw(fontir, (char *)text, styleflag, width, height); [5] don't hold your breath ... but if someone wants to have fun in the holidays the (4) and (5) are part of the same problem. Code Explanation: ----------------- The patch should be simple to read. They are three may parts: 1) BL_BlenderDataConversion.cpp:: converts the OB_FONT object into a KX_FontObject.cpp and store it in the KX_Scene->m_fonts 2) KetsjiEngine.cpp::RenderFonts:: loop through the texts and call their internal drawing routine. 3) KX_FontObject.cpp:: a) constructor: load the font of the object, and store other values. b) DrawText: calculate the aspect for the given size (sounds hacky but this is how blf works) and call the render routine in RenderTools 4) KX_BlenderGL.cpp (called from rendertools) ::BL_print_game_line:: Draws the text. Using the BLF API *) In order to handle visibility of the object added with AddObject I'm adding to the m_scene.m_fonts list only the Fonts in a visible layer - unlike Cameras and Lamps where all the objects are added. Acknowledgements: ---------------- Thanks Benoit for the review and adjustment suggestions. Thanks Diego for the BFL expertise, patches and support (Latin community ftw) Thanks my boss for letting me do part of this patch during work time. Good thing we are starting a project in a partnership with a Japanese Foundation and eventual will need unicode in BGE :) for more details on that - www.nereusprogram.org - let's call it the main sponsor of this "bug feature" ;)
