X_Material's mScene member variable wasn't properly set on merge if it didn't have an mBlenderShader defined. This patch always makes sure it gets set on merge.
example of usage:
0) Game Properties: text (String) and log (Boolean=True)
1) Keyboard Sensor set to AllKeys with log as logging and text as Target
2) Expression Controller: text=="quit\n"
3) Game Actuator: Quit Game
[1] <-> [2] <-> [3] .:. this will quit the game when you write quit + Enter
4) Keyboard Sensor: set to Return
5) And Controller
6) Property Actuator: Assign text property to ""
[4] <-> [5] <-> [6] .:. this will reset the string everytime you press Enter
# # # # # # # # # # # # # # # # # # # # # # #
Since the change is in the InputParser.cpp it actually affects all the text
input fields in the Logic Editor. So for instance you can use it in the
assign Property Actuator.
# # # # # # # # # # # # # # # # # # # # # # #
Connect an expression controller: text="idclip\n" with an actuator to disable
the Collision of your walls and you can re-create Doom with only Logic Bricks (:
I have no idea why this hasn't been implemented before (the DEFINES were even there already). But since the Ipo (Fcurve) Actuator supports it I don't see why Action and ShapeKey shouldn't.
More than a new feature or a bugfix this is actually a step forward into unifying them.
after discussion over the mailing-list it seems that it really makes no sense to restrict that. Specially since we have the "Property" playback mode that usually will be a float.
Since there is no need for do_version or whatoever I don't see a problem. Any Thoughts? Maube to allow it only through the Python API?
----------------------------------
While we are more and more moving towards enabling features in the Python API, it's also important to have Logic Bricks working with no scripts.
This option allows you to start the game with the mouse cursor on (it's on Render Buttons). The defalt is still off (no do_version needed here).
Support for physics is done by skiping the modifiers that
don't support mapping to original mesh. This mapping is
required to report the hit polygon to the application
by the rayCast() function.
Support for graphics is done by using the same render
function that blender uses for the 3D view. This guantees
equal result.
Limitation: there is still a known bug if all these conditions are met:
- Display list enabled
- Old tex face with a several textures mapped to the same material
- no armature or shape keys
- active modifiers
In this case, only a part of the mesh will be rendered
with the wrong texture. To avoid this bug, use the GLSL
materials or make sure to have 1 material=1 texture in
your old tex face objects.
Since rev.2 (hans ftw) we have a strange situation where horizon color was being used at Convert time for the WorldInfo background color (and for the fog). However through the Python API only the Rasterizer background color was being updated. On top of that the KX_KetsjiEngine.cpp::SetBackGround was using the WorldInfo bgcolor when render mode was the potato one (TEXTURED). Bottomline, when in potato mode the glClearColor used was the original one in worldinfo, not the API updated one in Rasterized.
implemented the support for animated colors and a workaround for non animated colors. To be cleaned if/when this bug is fixed:
[#25487] BGE: Object Color only works when it has a keyed frame
* also increased the size of the text. Now it supports 280 (or 140 unicode) chars.
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.

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" ;)
In windows this was producing Linking dependence errors because we have BLF_api.h in the /blenfont/ and blf_api.h in /python/generic/. It doesn't produces crash out of the box but I was trying to link both "api" files to the same project (Ketjsi folder). For the linking order was determining what header to use. A workaround is to "include" the file using some ../../ relative folder. But renaming it is less error prone.
Probably Ketsji folder shouldn't link to BLF_api.h anyways, but this is something I will look better later before another commit. In the mean time it's not a good idea to have 2 api files with the same name (for non case-sensitive systems).
from the tracker:
"""The required functionality is provided by the localOrientation property: setting this value will change the dynamic object orientation. This is because dynamic object have no parent and thus the local and world orientation are identical. However, setting worldOrientation will only change the scenegraph node, which has no effect as the physics controller will reset the orientation on next physics synchronization."""
This is a bug as old as the ability to change the actuator values through Python.
For the records: although Blender supports floats as frame values BGE doesn't. It could but it doesn't. So only integers (longs) will be valid start/end frames.
