I am trying to make a code that add one to a variable if you click the space bar. The code I wrote made the variable keep increasing if i hold the space bar but I don't want it to do that

You could use the getKey method instead of isKeyDown. However, there are limitations on applying getKey for this use. Best is to add a boolean field to track the state of the "space" key:
?
1
2
3
4
5
6
7
8
9
private boolean spaceDown = false; // last "space" key state
private int variable = 0;  // the int field being increased
 
public void act() {
    if (spaceDown != Greenfoot.isKeyDown("space")) { // is there a change in state of the "space" key
        spaceDown = ! spaceDown;
        if (spaceDown) variable++; // if change is from up to down, increase value of variable
    }
}
Of course, you could instead have the variable increase when the key is released. Just NOT (!) the condition on line 7.
