Collide vs. Edge Reached

[estie bryk]

I am teaching an App course using APP Inventor. My students are making a PONG game. One of the students encountered this error. The ball hits the paddle, but the block executed is that the bottom edge reached. I changed canvas height, changed the when paddle.dragged/set y to startY to set y to canvas height - paddle height so it stays on bottom.  I put in a text label to see which block gets executed (when ball.edge reached if edge= -1 then text="edge reached" and also when collided with other then text="collided with". As you can see from picture, ball collided, but text says "edge reached" and game over...

No difference if played on emulator or phone/tablet.

Any suggestions would be greatly appreciated.

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

Good point. Sorry. I'm still new at this.
Here is most of the blocks:

Maybe you need to raise the paddle away from the bottom edge more,

to give the paddle collision precedence over the edge bounce?

Try setting paddle Y lower by Ball1.Radius in the Ball1.Drag event?

Thank you. I tried it and it helped most of the time.
I set paddle.move to x= get currentX, y=canvas.height-paddle.height - ball.radius (so it is steady at @303 when canvas has height of 350)
When speed of ball gets too fast (above 50), then the event of edge reached is checked/called before ball collided event.
I have to look into what intervals the ball and paddle should be set to.
Thank you for your assistance.
