[Bf-gamedev] Using blender timeline features

[Owen Alanzo Hogarth]

Hi Sybren

My apologies for the generic question. Let me try to pin it down a bit.

Blender has the timeline feature where you can animate an object and play
it back using the timeline. In the game engine I wouldn't need to be able
to edit the bones and their attributes but I would like to be able to get
their position rotations, angle, scale etc.

Let's say that I author a 2 second animation in blender where I translate,
rotate and scale a cube. Blender stores all this data somewhere so that
when I press the play button it can recreate the animation in blender
engine.

What if I could export that data as say json for example, then load that
data into a game engine and play the animation in engine. So the
information that would probably be needed to be exported would be something
like:
1) timeline length of the animation
2) a list of keyframes
3) each keyframe would have maybe position, rotation, scale, angle of the
object
4) the type of object, the objects materials, textures, etc.

Best,
Owen
