@Chris Mordy is referring to an MIT tutorial and
Challenge 2: There is a slight bug when the ball hits the vertical sides of obstacle. Figure out how to program the ball to obstacle collision so that it bounces the way you would expect when the ball hits the vertical sides.
Mini Golf: Fling, TouchUp, TouchDown Gestures for App Inventor 2Mini Golf is an addictive little game app that demonstrates how to use the Fling, TouchUp and TouchDown gestures on Sprites. Hold down the positioning arrows to move the ball to the desired position on the tee, then Tee Off by flinging the ball toward the hole. After a hole is scored, the screen randomly sets up a new hole, providing a unique challenge every time. This tutorial is for App Inventor 2.
@ Mordy Sorry, I do not have a solution but the methodology is probably described here
I think the 'solution' might involve the discussion of Edge Reached in that article.
Did this help you find a solution?
