Reverse

Solved

Are you talking about the changes in the x,y position of some shape that you are drawing?
How are you computing the shapes next position? Can you change the equation so that the value of the next x,y position is in the other direction? Perhaps by reversing the sign of a variable in the equation.

@OP: please don't edit your original post as you did; look at the thread: it's completely useless for others now.

kind regards,
