Can also confirm that. Had a quick look at the code but can't see anything obvious in BLI_bvhtree_ray_cast.

I've been away for quite some time and am just getting familiar with current operations (GIT instead of SVN) and locating py modules in progress. One of the modules I had worked on so long ago was add_mesh_masonry which is a block wall builder. Not sure if what is here takes precedence or a merge is possible. Any guidance is appreciated.

Sorry. I forgot.

Example files are in the bug in the title : T43724 and T41599.

I would also like to see some example Python code, to see what it looks like from that side of things. Right now the callbacks are pretty easy to use. Does the introduction of a FunctionValue also require a Python programmer to use that type? Or will it be transparent?

Hey @jacky3horn, I can't recreate that here (Linux) but there are quite a few possible causes of such freezes/crashes. So please follow the tests below and tell us the results:

• Ensure both your OS and drivers are fully up-to-date.
• Ensure your GPU driver supports at least OpenGL 1.4.
• Use our latest builds from buildbot.
• Ensure you have installed MSVC2013 redistributable package (http://www.microsoft.com/en-us/download/details.aspx?id=40784).
• Try to disable any running antivirus.
• Ensure you have no python executable available in your %path% envvar.
• Try to re-download and re-install Blender.
• Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).
• Try to place this dll next to your blender.exe (software OGL, will be slow, but will show us if this is a driver issue or not).

(more or less copy & pasted from Bastien - again :P)

First Question : I think that is possible to make a collision callback which only takes the object in collision and the point, but yes will be never 0 arguments (minimal arguments like maximal arguments variable).

The patch just corrects crashes, because if we add font in overlay scene the font it's added in the scene which contains the logic controller, and yes it's change nothing for the final user.

I see. Although I would expect the default behaviour to take the color from the sky. Python can used to override when needed. The current behaviour seems unintuitive.

I still didn't understand what's the point of this patch. Does it change anything for the final user?

I don't disagree. It's my first try at changing / looking at the Blender code so if anyone has a better idea, please do implement it. Also I need to point out that this won't work for font objects which is a shame. So again, if anyone else knows how to do it or if it's possible then you're more than welcome.

It can be a matrix and I have both broadcast and full range versions. I will look into this possibly after I fix the XYZ hard coded paths.

If I read the code correctly, KX_GameObject::NodeGetWorldDimensions() results in a transformation of the world bounding box to local coordinates, only to convert it back to world coordinates. Seems like a waste.

Overall I think this is a very nice addition. It's something I've missed :)

@sindra1961, so could you test using the latest (Official, not Gooseberry!) build from buildbot?

I don't know enough about how we use Bullet constraints to give any feedback on the semantics of the code. However, I can suggest some changes that I consider code quality improvements.
