Not sure you can set thier velocity to zero. You need them to stop trying to trying to get to the goal. So when effected they just stop walking. Think of it this way if you set them to zero velocity it lasts a frame and then they start again which is quicker then blink of an eye.
So they need to stop persuit on either till they land or delay a second. I’m guessing anyway I could take a look at the project. I think we have the launch right it’s a matter of getting the ai to stop moving when it’s activated.
Could the movment be gated based on is walking? So they don’t move if in air?
