Any resources with a character controller with only raycasts? No physics

Enemy System without Humanoid

sorry for late reply, I didn’t test it first because I need to modified some features of the script to makesure it stable for your game. So you need to make the primaryPart of the NPC like this: [Screenshot 2025-05-26 163106] Perfectly big enough for the NPC. So I like to add some tweaks here: local distance = function(v1, v2) return math.sqrt((v2.X - v1.X) ^ 2 + (v2.Z - v1.Z) ^ 2) end local SpeedMul = 16 -- walkspeed I think (studs/s) local JumpMul = .5 local FallSpeed = 2 local RotateSpe…

Thank you, but is there any way to stop bigger characters from having this collision issue?

I didn’t know BlockCast exist but I think this is the best result:
non-humanoid NPCs (1).rbxl (75.9 KB)
it works with big character and small character collision.
