Hey, recently I started messing arround with the physics car script that comes with gamestudio. I'm trying to create a funny race game with power-ups. One of the power-ups is a temporaly increase in scale. I've already created the code that makes the wheels and car change in scale. But the problem is that the wheels stay at the same postion from the car as it was in the original scale. My question is, how do I change the physics joins between car and wheels in real-time based on the scale of the car. Hope someone can help me, much appreciated.

you have to unregister the physics for your wheels when changing scale and after that register new! I think this is the only way.

So if I understand correctly the easy way is to remove the old wheels and just ent_create new ones, every time I change the scale.

yes I would do it this way

- add constraint
- scale wheel
- if wheel scaled remove old constraint and add new constraint afterwards
