Well see i am making a new game(Took forever)

But see i noticed i can hold in Space bar and the counter will keep going up here si the code.

```php
onClipEvent (enterFrame) {
    if (Key.isDown(Key.SPACE)) {
        _root.pu += 1;
    }
}

```

But i wouold want it to only go up when the SPACE bar is realesed

</div>

quick test …

```auto
onClipEvent (enterFrame) {
if (Key.isDown(Key.SPACE)) {
ok = true;
} else {
if (ok) k++;
ok = false;
}
trace(k);
}

```

like that?

</div>

or a shorter method

```auto

onClipEvent(enterFrame){
	if (s-(s=Key.isDown(Key.SPACE))>0) _root.pu++;
}

```

sorry kax, couldnt resist 😉

</div>

onClipEvent(enterFrame){  
if (s-(s=Key.isDown(Key.SPACE))\>0) \_root.pu++;  
}

I will test these both

onClipEvent (enterFrame) {  
if (Key.isDown(Key.SPACE)) {  
ok = true;  
} else {  
if (ok) k++;  
ok = false;  
}  
trace(k);  
}

😉

s is the variable the Key.isDown(Key.SPACE) is saved to, this happens every frame 🙂 Obviously. This happens in the if statement… again, fairly apparent. When it happens is after the first “s-” so if Key.isDown(Key.SPACE) is not the same at that point in time, that s in hte “s-” still holds the value of the previous frame - this value being either true or false, which numerically is either 1 (true) or 0 (false). And since the first s is not the current s, we are subtracting the values of Key.isDown(Key.SPACE) for this frame and the previous frame where it was last set: Last frame Space is down minus current frame space is down. Since we want to know when the space bar is released, we want the previous frame to be true and the current frame to be false or true minus false. That is the same as 1-0 which is 1 which is greater than 0. If both are true, you get 1-1 which is 0 and not \>0. Both false, 0-0, or 0 and not \>0. And with 0-1 you get -1 which is also, not \>0 (-1 is in the case of just pressing the space bar). So in the end the only thing greater than 0 is the releasing of space. You could also say ==1, but the \> sign is one character and == is 2 SAVED TYPING! 😉
