Part12Studios : Thanks. The movement works but i don't understand how to not move the sprite when you click on the left button. It's come from this part but i don't find a way to skip that part.
"MouseDown = 1
->Set MouseX to mouse.X-sprite.X
->Set MouseY to mouse.Y-sprite.Y"
I want that the sprite keep it's initial position when I left clicked.
Vtrix : I don't want the sprite to follow the mouse, I want it to reproduce the mouse movement. I want that when i clicked on the left mouse button and, for example, i go to the left with my mouse the sprite go to the left to. But i don't want the sprite to teleport to the mouse position. I want it to keep it's initial position and reproduce the movement of the mouse. Like you said, i know how to make a sprite follow the mouse but i don't know how to make a sprite reproduce the mouse movement.
