Ghost to only some objects

Hello everyone.

I don’t know if this is possible but I want some objects to be only ghost to a certain object. can this be done?

I’m not sure how, but in 2.6 there is apparently collision grouping, which does that.

There is?

Where?

I use that with python. You have this code that can exclude an object from Bullet or enable it :

obj.suspendDynamics()
obj.restoreDynamics()
Be aware that if you input some actions in some actuator, it’ll be take in account when you restore Dynamics, so it needs some reset before restoring it.

Edit : Still you can move the object using it’s obj.position when Dynamics are suspended.

Or you could just try finding another way of achieving what you want. I am sure there are always more possiblities to achieve something. What do you want to do?
