Help With Canceling a pathfinding

Help and Feedback Scripting Support

Hi. How would I go across canceling a pathfind, in my horror game after a player comes in range with a demon the demon chases them once they die the pathfinding breaks, and the demon tries going to the old destination and walks into walls how would I fix this?

i did not know thanks!!! :slight_smile:

its okay but changed it to help and feedback…

How are you currently pathfinding? If you want to “cancel” pathfinding then it would be helpful if you provided your current implementation. To cancel pathfinding is to stop the operation from happening midway and I surmise you’re moving through points with a for loop or something.

#8

what do you mean??? like im sorta good at pathfinding but i cant stop the pathfinding when it has not reached its goal yet

#9

What I mean is that it would be helpful if you showed how you’re currently pathfinding. Your code that handles pathfinding for your NPCs. Do you have it? If so, please post it in a code block so we can see exactly how you’re pathfinding right now.

sure it might not be perfect bc i broke it testing stuff but i will send in a min

its a bit sloppy but here it is

It seems like you have everything down for the most part already. If you need to completely cancel the pathfinding, seems logical to just throw a break statement at the bottom of your if statements which are checked after using findTarget. break terminates a loop, which would stop your NPC from continuing to follow nodes.

thanks! i will try this :slight_smile:

wait im confused exactly where???
