If you have boolean variable like

Code:

new isEventRunning;

instead of doing this

Code:

if(isEventRunning) {
    isEventRunning = false;
    // do stuff
}
else {
    isEventRunning = true;
    // do stuff
}

you can instead do this

Code:

if((isEventRunning = !isEventRunning)) {
    // event is running
}
else {
    // event isn't running
}

or

Code:

if((isEventRunning ^= 1)) {
    // event is running
}
else {
    / event is not running
}
