This project simulates the path of an arrow being fired. Click above y = 0 to set the vertex (highest point) of the shot. The arrow will fly towards that point and then begin to drop. Clicking lower than y = 0 will set (-240, 0) as the vertex and the parabola will pass through the clicked point. Press T to show/hide the target. Due to the way this is coded, arrows fired straight up go really fast :P
Thanks to the Scratch Wiki for the "point towards x: () y: ()" custom block script! (https://en.scratch-wiki.info/wiki/Point_Towards_()_(block)#Related_Suggestion)
