Just some additions:
-Better said you have to change the variables with a value of 8. You just have to find out per trial and error whats rightZitat von Kelven
-You could also have an even better effect if you don't just delete the event but put in a cycle where the coordinates are recalculated and then the gamma of the picture is changed (I normally use a change of 25) of course then you have to use a wait, recalculate the coordinates again and then change it back
