Please add a way to update the ITransformer and PositionConstraints at runtime

[marcusx2]

There is currently no way to change the ITransformer being used by a grabbable at runtime. Here is the use case: I have a key, which the user can grab and move, rotate as he wants. Once I place the key in a keyhole, I want to use OneGrabRotateTransformer instead of the GrabFreeTransformer, so the user can only rotate the key now.

I tried the InjectOptionalOneGrabTransformer method from the grabbable. It doesn't work. None of the "Inject" blabla works. Even in the GrabFreeTransformer itself, I can't update the constraints using InjectOptionalPositionConstraints for example.

Please, is there a way to do this at all?

Hi @marcusx2 apologies for the delayed response on this!

The Inject methods are meant to work at setup time (before Start() is called) so they are not guaranteed to work at runtime.
You can change the ITransformer being used by a grabbable at runtime by initializing the transformer before injecting.

An example of switching from a GrabFreeTransformer to a OneGrabRotateTransformer at runtime :
_rotateTransformer.Initialize(_grabbable); _grabbable.InjectOptionalOneGrabTransformer(_rotateTransformer);
