Reflect a rigid body without rotating it

Hey there,

you might just take the rigidbodys velocity and "reflect" it according to the object you hit.

Simply access the velocity vector and use This Function to "invert" the vector. Finding the normal to do so will be your problem though (I think the Collision information provided by OnCollisionEnter might provide it). If you need more specifics on this topic you should post more information about your setup/code/objects, to clarify what you want to achive.
