Just watch and relax. I will teach you how to make this. I V
1 make a "when flag pressed" and add a "go to 0,0" 2 under that add a forever loop with move "10 steps" then "create clone of myself" after that add "if on edge bounce" 3 (optional) you can add a "change color effect by 1" into the loop 4 now add a "when touching wall change rotation by 3" into loop 5 make a "when I start as clone" under that make "what 7 seconds" "delete this clone"
