Does anyone know how to make an object move when you walk into it in UDK? So far I’ve only worked out how to make stuff move when you shoot at them but not when you walk into them.
Normally it should work like this: ?v=NfV6Xyz_tFI 
Thanks. 
Also is there a way to make UDK play a sound when the rigid body hits a surface? So far I only have a thing in kismet which plays a sound roughly as the object hits the floor but the way it falls is different every time so sometimes it is really out of synch.
With UDK you mean the UE3 or the UE4? Because normally this here is a UE4 forum ^^
For the UE3. Sorry I thought this forum was for both.
This video will answer your question: ?v=91_k-HGLq5M (impact sound should do what you want)
