Here is an idea for a pause method that has not been used as far as i can see.
Tell me what you think
1 | if(buttonPressed()) { Greenfoot.setSpeed(0); } |

About pause ideas
have not tried it but to start again you could make another button with code
1 | if(buttonPressed()) { Greenfoot.setSpeed(what speed you want); } |
@kiarocks, the minimum setSpeed value according to the Greenfoot API is ONE (1), therefore, your can only create a long delay, not a pause, using setSpeed.
If you are trying to create a situation where no action is taken until a certain event occurs, like a buttonPress or keystroke, you could use:
BUTTON-PRESS
KEYSTROKE
1 2 3 4 5 | boolean anyButton = false;while (!anyButton){ anyButton = Greenfoot.mousePressed(null);} |
1 2 3 4 5 | String myKey = "";while (myKey = ""){ myKey = Greenfoot.getKey();} |
darn, you can set the slider to 0, so i thought it might be possible. didn't get a syntax error when tried
would setSpeed bump it to one if you type 0?
Well, as danpost pointed out, the documentation says: "The value must be in the range (1..100)". If you don't follow the rules, then there are no guarantees about what will happen. It might move the value in range, it might ignore it, it might throw an exception, or something else altogether. Even if it had some behaviour now, you couldn't be certain that it would do the same thing in a different version of Greenfoot.
what is the getSpeed method??
There isn't one.i think a pause(int time) method would be a great thing to include with Greenfoot.
