Unity产生带有铰链关节的GameObject

Question

I'm working on a level generator in Unity for an endless runner and I want to spawn some prefabs with hinge joints.

The trouble is that when I spawn an object with a hinge joint, it retains the anchor and connected anchor from when the prefab was saved, not relative to its spawned position.

Any idea how I can fix this?

Answer 1

Instead of having the joint in the prefab. Why don't you use the AddComponent<HingeJoint> method in runtime when you generate the level to do the connections.

Answer 2

I solved this problem with adding an Rigid Body(IsKinematic=true) as parent and set the Connected Rigidy Body property to this. Spawning the parent keeps the Connected Anchor in place.
