Playing sounds on object collision without sound repeating itself

About the spheres or sphere-like shapes that can roll over longer distances and trigger the “hit” event all the time: I had this problem, too.

Solved this now after hours of testing. It’s actually a problem that is quite easy to solve: Have a variable “Last Velocity”. On Hit, check if Length of the Vector “Current Linear Velocity - Last Velocity” is bigger than a threshold (50 worked for me), if yes then set the Last Velocity variable to current velocity and play the sound.

The idea behind it: Hit events where you want to play the impact sound generally occur with a sudden & significant change in velocity.

Here the part of the blueprint for this check:

Hope this helps!

Yea but when do you decide to reset it? I tried this resetting the value when velocity was near 0 but didn’t work well.
