I cant figure out how to only apply damage to characters inside the trigger sphere. What nodes should i use and how?

I don’t see your sphere collision So, pretty much, you just get all actors inside the sphere collision, and only apply damage to it.

Or, you can use a Radial Damage and just use that radius to cause damage to surrounding actors.

thanks for the response! i couldn’t get the sphere to work, so instead i tried using radial damage i got it close, but for some reason my character takes no damage.
