Select box code not working

By excitedbubbles, with 1 reply.
Replied to by nccb, about 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

Ah yes, sorry I forgot that it was a Java 11 method. We're currently testing Greenfoot 3.6.0 which will be based on Java 11, which should be out in a week or two.

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

Character Dash

By loldertroll, with 2 replies.
Last reply by loldertroll, about 7 years ago:

Sure -- pause the scenario and drag it with your mouse. No -- seriously. You will need an int timer field to regulate the dashing time. A positive time value means it is dashing. Also, you will need a boolean field to track the state of the trigger key so holding it down will not cause constant dashing. All you should need to do when triggered is set a positive value to the timer. The act method should check the timer value and have it count down when positive.

Mass to health ratio

Last reply by Super_Hippo, about 7 years ago:

I have no experience with using external files, so I can't help you with that one. What I would do instead would be to use the UserInfo class. Which obviously doesn't work easily for two-play-games like you described because you can only read other user's data but don't write anything to their files. Sending it over is probably more complex than figuring that I/O out.
