.b3d get child?

Blitz3D Forums/Blitz3D Programming/.b3d get child?

Chroma(Posted 2007) [#1]
Totally forgot how to do this. I'm working on a mock up POW/MIA memorial and want to keep everything in one .b3d file.

Anyone remember how to access children in a .b3d model?

My_level=LoadAnimMesh("Memorial.B3D")
Child=FindChild(My_level,"Child_I_AM_Looking_For_Name")

You may also use CountChildren and GetChild.

Naughty Alien...that's why I'm posting. That doesn't work...

I'll give GetChild and CountChildren a shot. Thanks.

Mr. Naughty will help...and if this not work, then somethings very wrong with your B3D file..

I had a similar problem only to find that because I was using Milkshape, you could only find the joint and not parts of the model.

Apparently Milkshape exports as a single root file for the mesh although the joints are "findable" and manageable.

Something like that anyway.
