Creating a stable movement controller for NPCs

[dthecoolest]

Yep using PID will just end up as LinearVelocity or Body velocity with enough tuning.

Personally I just use a flat vector force and add a drag force to maintain constant speed which has created a humanoid like effect.

How do I limit the velocity of VectorForce?

It’s intended for use even without assembly linear velocity, it works as a formula of drag. [image] It’s simplified so everything else is a constant, area, drag, density. Yep -velocity is intended because drag force acts in the opposite direction of movement. But yeah I think the formula is a bit incorrect it results in a weird error. This should be the fixed formula: dragForce.Force = -velocity.Unit*(speed^2)*XZVector @vxsqi Example script, insert into starter character scripts, prett…
