cef5c4b765 Add Fh/Rot Fh to Bullet. 2008-09-29 06:58:49 +00:00

0b622fc07f added anisotropic friction support for Bullet. Both for static and dynamic objects 2008-09-29 03:09:03 +00:00

f8fb61f9fa enable -noaudio option, so it actually works (and doesn't get overwritten by a game flag). audio initialization delays startup of game engine 2 seconds
add -nojoystick commandline option: it takes 5 seconds everytime to start the game engine, while there IS no joystick.

In other words: blender -noaudio -nojoystick improves workflow turnaround times for P - ESC from 7 seconds to 1 second!

Improved Bullet soft body advanced options, still work-in-progress. Make sure to create game Bullet soft bodies from scratch, it is not compatible with last weeks builds.

9d3c77ec62 support concave soft bodies, preliminary. could be used for cloth too. need vertex pinning/constraint attach to other objects. 2008-09-26 06:25:35 +00:00

a1bef84ea8 Allow Bullet soft bodies to be created using a AddObject actuator. Added a fake world coordinate system to game soft bodies, although the vertices are already in world space.
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)

6732718ef1 don't apply vertex transformation for deformable game soft bodies.
set a fake world transform for game soft bodies, based on center of the AABB, so visiblity and some game logic works. note: this world transform is not smooth.

3b09c0b0d5 Created a KX_SoftBodyDeformer for real-time soft bodies.
Added SetDeformer/GetDeformer() to KX_GameObject.
Store mapping between graphics/soft body vertices (work-in-progress)
Real-time soft body integration is still very premature, but
for a quick preview, see this testfile:

1c29d02305 BGE real-time soft bodies, step 2 / 3: create a btSoftBody. Next step is hooking up / deform graphics mesh and choose collision shape.
Note: feature is still disabled.

22a50402ef BGE patch: allow Bullet mesh shape sharing for objects copied with ALT-D. 2008-09-20 21:33:54 +00:00

41a0b56b70 BGE patch: new Physics button and margin parameter in Logic panel. Change subversion.
The Physics button controls the creation of a physics representation 
of the object when starting the game. If the button is not selected,
the object is a pure graphical object with no physics representation
and all the other physics buttons are hidden.
Selecting this button gives access to the usual physics buttons.
The physics button is enabled by default to match previous Blender
behavior.

The margin parameter allows to control the collision margin from
the UI. Previously, this parameter was only accessible through 
Python. By default, the collision margin is set to 0.0 on static 
objects and 0.06 on dynamic objects. 
To maintain compatibility with older games, the collision margin
is set to 0.06 on all objects when loading older blend file.

Note about the collision algorithms in Bullet 2.71
--------------------------------------------------
Bullet 2.71 handles the collision margin differently than Bullet 2.53
(the previous Bullet version in Blender). The collision margin is 
now kept "inside" the object for box, sphere and cylinder bound 
shapes. This means that two objects bound to any of these shape will
come in close contact when colliding. 
The static mesh, convex hull and cone shapes still have their
collision margin "outside" the object, which leaves a space of 1
or 2 times the collision margin between objects. 

The situation with Bullet 2.53 was more complicated, generally
leading to more space between objects, except for box-box collisions. 

This means that running a old game under Bullet 2.71 may cause
visual problems, especially if the objects are small. You can fix
these problems by changing some visual aspect of the objects: 
center, shape, size, position of children, etc.

ba9d3aa4ab BGE patch: fix transform bug on compound shape: child shape didn't take into account parent inverse node. Fix scaling bug on instantiation of compound shape: child shape didn't have correct shape. Note: global scaling doesn't work on compound shape (limitation of Bullet); don't set any scale on the top dynamic object. 2008-09-13 11:46:07 +00:00

cb89decfdc Merge of first part of changes from the apricot branch, especially
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:

* GLSL support in the viewport and game engine, enable in the game
  menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
  gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
  storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.

* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
  An extra texture slot shows up once the last slot is used.

* Memory limit for undo, not enabled by default yet because it
  needs the .B.blend to be changed.
* Multiple undo for image painting.

* An offset for dupligroups, so not all objects in a group have to
  be at the origin.

3d3527eb6d BGE bug #17411 fixed: the always sensor is called before the the scale of the object is applied. The scale is now applied to the shape before the creation of the rigid body. 2008-08-21 21:04:42 +00:00
Benoit Bolsee
e912ca9331 BGE bug #17491 fixed: BGE, Dupli instance with different scale, massive slowdown.
The root cause of this bug is the fact that Bullet shapes 
are shared between duplicated game objects. As the physics
object scale is stored in the shape, all duplicas must 
have the same scale otherwise the physics representation
is incorrect.
This fix introduces a mechanism to duplicate shapes at
runtime so that Bullet shapes are not shared anymore.
The drawback is an increased memory consuption. 
A reference count mechanism will be introduced in a 
later revision to keep Bullet shape shared between
duplicas that have the same scale.

056a33ac69 new game-menu option 'Record Game Physics to Ipo'
including implementation. hope it works, and doesn't break to much.
it bakes physics objects transform into ipo, every frame of the running gameengine.
When you disable and run the game again, it clears the ipo's again. just for physics objects at the moment.

(perhaps some better UI in the future?)
