Initial object position won't affect animation #263

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
It looks like initial object states like rotation, scale and position will be 
deleted when they have animation data. This can lead to some strange results 
that do not reproduce the way things behave in blender. 

Let's say I have an object with an initial position and I just animate the X 
axis. With the current code z and Y will be set to zero as soon as the 
animation starts while in blender they keep their old values.

To fix this, we could load the initial transformState before applying any 
keyframed values.

I have attached a version of gkAnimation.cpp that does this.

Is this safe to do that way or will it break other things?

My solution had a problem with the rotation. The following file fixes that.

Would be great if you could provide a svn-patch-files

I probably can do that. But actually I rarely used SVN before. I am always 
using git. Do you have any pointers on how I should create one?

Hmm, not sure. I always do this with eclipse. Not sure about how to do this on 
the command line. I assume something like: svn diff. I use checkout out gamekit 
via git svn, I actually don't know how to create a corresponding svn-diff. 

If you want we can test git-patch as well...
