Button Function

Last reply by Super_Hippo, over 7 years ago:

Yeah, line 7 should have been: <Code Omitted> This line does remove ALL numbers from the world, not only the unsolved ones: (so your comment isn't correct there) <Code Omitted>That's why line 16 (or my old line 7) is not needed.

There are buttons in the shop that upgrade and buy an actor. For example, if I press the buy button, I need to make a chicken visible if that makes sense.

Select box code not working

By excitedbubbles, with 1 reply.
Replied to by nccb, over 7 years ago:

One thing is that PlayerDeath is never set back to false. I'd also be careful generally about using static variables in the world -- as far as I remember, they are not reset when you click Reset, only when you recompile. This affects PlayerDeath but also leftSide etc. Instead of using ImageScrollWorld.leftSide, use getWorldOfType(ImageScrollWorld.class).leftSide and remove the static.

Counter for a pong game?

The leftCounter field in your Ball class has issues. First, it is never assigned a Counter object -- namely, the one created and added into the world at lines 43 and 44 and referenced at line 12 in the background class. Since it is already referenced there, it might be best to remove line 7 in the Ball class and replace line 18 with the following: <Code Omitted>

Wow that works perfectly! I just stuck it in my WinLeft method and everythin

You are probably not putting the attempted codes in the right place. Try within an act method.
