Help Debugging Unit 3 Lesson 27

Hi All!

I have been trying to help a student debug their project and we are stuck. We expect the pink alien to move the ball passed the goal line to score points. We have added watchers as well and have not been able to get the alien to score.

Any help would be greatly appreciated!

The pink alien (player 1) is scoring. The problem is that for player 2, the green alien, you’re always adding a point without checking if the ball’s y coordinate is less than 100.


I see a conditional block that determines when player 1 scores, but for player 2, I don’t see any conditional blocks that tell when the score should happen. (when the ball is touching goal 1).

Hopefully that’s enough to get you started! Check back in if you still need help!
