[Solved] CSG rotation by script does not rotate childs

[Roland]

Maybe a bug or behavior by design?

 

If you have a CGS object with a child object.

 

In the editor the child will rotate along with the parent object when the parent is rotated. That's Ok and expected behavior. However if you rotate the parent object by a script (simple Turn command) the child does not rotate, only the parent.

 

 

Tested same thing with two mesh objects (fbx) and in that case both rotates as expected when parent is rotated (both by script and in the editor)

Does the child CSG object have a mass or a script attached? If not, it will get collapsed along with the rest of the CSG objects at runtime.

[Roland]

Okay. I can confirm that adding a 'dummy' empty script to the child solves the problem.

I really don't see why this has to be done, but accept it as a solution . But its a bit tricky when things behaves different in the editor and in run-time.

 

Thanks macklebee

It has been discussed before. CSG brushes, for performance reasons, are collapsed during runtime. If a brush doesn't have a script attached or physics enabled then it gets collapsed.

[Roland]

Performance is always a good reason

There are some cases in which you do need brushes not collapsed. The indicator lights in the Vectronic Demo are an example as they need to be told what color to change to during run time.

I still think adding a checkbox in the properties section to collapse or not would be a better solution.

Yeah. Add an empty script feels a bit silly
