You made some mistakes it seems, but I corrected it and it works perfectly! Thank you so much @danpost . You've been the person behind my whole project since you answer all possible questions I find in this platform. Thank you again. And here's the corrected code for those who need it:

The actors' images should change when you "Reset" the scenario.

You aren’t calling the jump() method, only the checkJump() method. You generally don’t need the gravity variable. If you want to be able to adjust the gravity strength you need to adjust how much vSpeed is changed when the object is falling

You need to track the mouse‘s state: <Code Omitted>If you want pressed only to be true if the mouse was clicked onto a specific actor, replace the null in line 4 with the specific actor, BUT NOT in line 5! <Code Omitted>

No, that are just example methods that show what should be done in a certain case. These methods are: getSpeedX() getSpeedY() setSpeed() paintToColor() setColors() They just indicate what could be implemented right there

thanks for the code I understand better by using a private access for the buttons which allows to differentiate them, I did not think about it thank you

Not if implemented properly.

Where did you put that? Show entire class codes please.

oh! that could work. I will see if i can figure out how to code that.

Again refer to my demo. If you have behavioral issues with the code, then show that code and ask questions. Or, you can upload the scenario with the unwanted behavior (or a sample exhibiting that behavior with the same problem code).

is your oval an actor?

Move line 7 to after line 12. This will limit the score divisibility check to only when the score changes.

I guess you are looking for something more along these lines:

Answers to hints: 1) every other move; 2) same as (1), but not on same moves; 3) always; 4) when at (right) edge (or after 7 moves, if starting at left edge). If you flip the boolean value every act, it should not be hard to move in a zigzag across the board using an if conditioned on the boolean.
