Cloth force and collision

Unity Engine
1

I’m curious if Unity’s cloth system supports the following two use cases:

  • Let’s say there’s a cloth banner hanging from a pole. An explosion occurs nearby. The cloth should be pushed away from the explosion. Is there a way to apply forces to the cloth programmatically?
  • Let’s say that while the cloth is moving, it passes over a fire, which is a game object with a trigger collider. Can the cloth cause the trigger to fire?

Thanks,

For the explosion you should be able to actively change External Acceleration when the explosion happens. If the explosion is a random position you will have to write a script to determine the direction of External Acceleration. Not difficult to do btw.

I have never used a cloth as a trigger but you should be able to use a trigger collider then use OnTriggerEnter, have you tried this?

Thanks, I’ll look into External Acceleration. I wasn’t familiar with it.

I tried to get the cloth to set off a trigger, but it didn’t work. For testing, I had a capsule collider, which I added to the Cloth’s list of colliders, set it to IsTrigger, and made it overlap with the cloth, but it didn’t fire the trigger.
