881802d8a3 BGE patch #10492 approved: getLinearVelocity() now can provide local velocity as well. This patch is harmless and backward compatible; it can go safely into 2.46 release 2008-05-06 20:55:55 +00:00

3a430c33d2 fix BGE bug #8869: Added objects are not lit correctly
The current layer information is now stored in KX_GameObject and inherited from the parent object when dynamically added. This information is used during the rendering the select the lamps. As the selected lamps are always coming from active layers, their position and orientation are correct.

f4cc03b0f1 Better fix for BGE bug #7892: dRot is reversed on dynamic objects. Make sure that graphic, Bullet and Sumo(deprecated) objects rotate the same way. This fix reverses the rotation of non-dynamic objects compared to 2.45: you will need to change the sign of dRot in 2.45 games for them to work correctly in 2.46 2008-04-23 21:48:17 +00:00

4bab327c1b fix BGE patch #7892: dRot motion is reversed on non-dynamic objects
Positive dRot motion actuator will now make the dynamic and non-dynamic objects rotate counter-clock wise.

e7384c9dd2 Commit patch #8799: Realtime SetParent function in the BGE
This patch consists in new KX_GameObject::SetParent() and KX_GameObject::RemoveParent() functions to create and destroy parent relation during game. These functions are accessible through python and through a new actuator KX_ParentActuator. Function documentation in PyDoc.
The object keeps its orientation, position and scale when it is parented but will further rotate, move and scale with its parent from that point on. When the parent relation is broken, the object keeps the orientation, position and scale it had at that time.
The function has no effect if any of the X/Y/Z scale of the object or its new parent are below Epsilon.

435a49dfe7 New rayCastTo() python method for KX_GameObject:
rayCastTo(other,dist,prop)

Look towards another point/KX_GameObject and return first object hit within dist with a property that match prop, None if no object found or if it does not match prop.

Parameters:
  other = 3-tuple (xyz coordinates) or object reference (target=center of object)
          (type = list [x,y,z] or object reference)
  dist = max distance of detection (can be negative => look behind)
         If 0 or omitted => detect up to other
	 (type=float)
  prop = property name that object must have
         If empty or omitted => detect any object
         (type=string)

52293831b2 BGE fix: game object to controller links consistancy maintained regardless of order of deletion
AddObject actuator forces last created object to hang in memory even after object is removed from scene => bad link between object and physic controller that causes Blender to crash in case a python script tries to use it (bad programming anyway). 
This patch avoids the crash by maintaining consistent links at all time.

e4790aef46 Improved OpenGL Shader Language support for game engine. The python interface is much simplified. Drawback is that scripts need to be updated next release. Testfiles:

2e6d576182 Sorry to break the cvs-closed status, so if you really need to make a new 2.40 build, just disable the game engine if it doesn't compile for a platform. Again, sorry if this breaks non-windows platforms, but I hope people help to get this amazing fix working for all platforms. Armature-fixing contribution from Snailrose. Also lots of cool things from Snailrose and Lagan.
Armatures are back
Split screen
Double sided lightning
Ambient lighting
Alpha test
Material IPO support (one per object atm)
Blender materials
GLSL shaders - Python access
Up to three texture samplers from the material panel ( 2D & Cube map )
Python access to a second set of uv coordinates

b6d9fbf0db fixed the mouse-over sensor,
added raycast support for bullet (no triangle-mesh support, soon)
added python methods for 'getHitObject', getRayDirection, getHitPosition and getHitNormal for mouse over sensor,
which makes it easy for a shootout.blend demo :)

6c4ae1eb54 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.

3dd18c5c34 Added an UpdateTransform callback from SceneGraph -> Physics.
Profiling revealed that the SceneGraph updated every physics object, whether it moved or not, even though the physics object was at the right place.  This would cause SOLID to go and update its bounding boxes, overlap tests etc.
This callback handles the special case (parented objects) where the physics scene needs to be informed of changes to the scenegraph.

Added Python attributes (mass, parent, visible, position, orientation, scaling) to the KX_GameObject module.
Make KX_GameObject use the KX_PyMath Python <-> Moto conversion.

ae9233a5b0 1. Check material names passed to the physics engine (for collision sensors.)
Consider:
gameobj->getClientInfo()->m_auxilary_info = (matname ? (void*)(matname+2) : NULL);
It works if matname is "MAblah", but not if matname is "".

2. Added constructor for struct RAS_CameraData.
3. Added initializers to the struct KX_ClientObjectInfo constructor
4. Collision sensors won't detect near sensors.
5. A stack of minor tweaks, adjusting whitespace, using ++it for stl stuff.

00291b5cf4 [GameEngine] Commit all Kester's changes made to the gameengine to restore 2.25 like physics.
[SCons] Build with Solid as default when enabling the gameengine in the build process
[SCons] Build solid and qhull from the extern directory and link statically against them

That was about it.

There are a few things that needs double checking:

* Makefiles
* Projectfiles
* All the other systems than Linux and Windows on which the build (with scons) has been successfully tested.
