what why :frowning: I’ve been dealing with a similar issue and have been trying a lot of methods. Like the pathfinding is useful but then I also want the npc to like strafe. I’m just wondering how to make like ranged NPCs and melee NPCs.

make a event for the ranged npc to fire a bullet (example) and just fire the event whenever pretty simple samething with the melee part just use magnitude if you want a easy way of doing melee and so on (its quite efficient actually but not when you want changeable hitboxes)

How do you think I could do a state machine with this? To go through certain behaviors, so it’d be easy to go from Idle or like Travelling to Combat.

Ex:
–Defaults–
Idle
WanderRadius
WanderWaypoints
–Active–
Melee Combat
Ranged Combat
Travelling (Point A → Point B)

What rig are you using for the zombie? Could you elaborate on it?

I’ve had this same issue due my rig being scaled improperly.
Is the model Scale set to 1, did you do any rescaling, etc.?

Also, does the same script do this with all characters? That is, a random dummy character from the Toolbox for example.

attributes? like attributes being an artificial state thing?

also i dont think you should be asking for these stuff in a topic about where i need help.
if you need help why not make your own topic

I’d say it’s simply just calling it too much. And the parameters are probably over-specific. If possible, switch the movement function to :Move() and make it call less. It has too many way points.

ive realised what you’ve meant and, it is not ideal and hasn’t fixed it
why would you use :move() anyways
