Did you manage to find a solution to this problem? I’m in a similar situation :S This is my Solution so far:
but it not really working (I want it to move again if it has been hit by another projectile.) . I also tried a solution were the component is destroyed and then i add a new one to the game object which is a very bad solution tbh but it works. Though the overhead for that compared to just resetting the Projectile move component is probably great. The Set Active with the reset bool seems to do absolutely nothing
