So I was making a some type of boat creator game and that’s when I got stuck on trying to figure out how to weld a part will a tool but nothing worked
Are you using hte mouse to move the part, like in build a boat to survive?
Have you tried using mouse button 1 down to grab the Part, then move it with the mouse, then when mousebutton1 is up (UserInputService.InputEnded) then create a weld if it detects a .Touched event between the Part and another Part of the boat model.
