@Ray Aznable i saw the pic. In this direction u need to push slider backward/towards you When i made this it was reacting opposite. After making,the draggable change it velocity and some inner physics Thanks 4 P,C&R✨
... @Anomynous but im sorry anomy san I have spent alot of time stressfully during my 24 times of restart to solve this. just if I knew about this earlier. 5 stars is an absolute for you... u need to write down about how to correctly slide ball. maybe u can put those pictures at your first comment.
The stairs on the side for B are unnecessary. Draggable dropping the ball will be difficult if they do not know.
