Any idea how to make a "Toggle" button?

By Tym5, with no replies.

I need to assign a key a "toggle" feature, so when it is pressed I will press another button and whatever shape is assigned to the second key fills in with a solid color. Any Ideas? I am not looking for answers (I like doing all the problem solving on my own) just ideas or someone to point me in the right direction.

Please don't upload Greeps code.

By davmac, with no replies.

Just a re-iteration of something that's been said here earlier: please do not upload any code for the "Greeps" competition.

Or of course manage the indentation properly as you go, in which case you don't tend to run into problems like these nearly as much...! :)

So instead of basing a change of level off the asteroids, I thought I'd base it off of the score, so i can have multiple levels. I know I need to assign a variable to the counter so i don't get the non-static method error, but I'm not sure how to do so. private void NewLevel() { Counter counter = Counter.getValue(); if (counter == 69) { Greenfoot.sto
