Raycast in Roblox not hitting what I expect

Most of the time it's the direction argument. It isn't a target position, it's a vector whose length is how far the ray goes. So: local dir = (target - origin).Unit * 500 local result = workspace:Raycast(origin, dir, params) If you pass the target's Position as the direction, the ray goes off somewhere random. The second most common cause is the ray hitting your own character or tool first. Set up RaycastParams with FilterType = Enum.RaycastFilterType.Exclude and put your character in FilterDescendantsInstances. Also, parts with CanQuery off are skipped, and invisible parts are not. A transparent hitbox will block the ray unless you exclude it.
