This depends on the event, that you want to toggle the animation with. mousePressed and keyPressed are always called, but you also might use an event, which is stoped by noLoop() as well. In this case its better to use a boolean: Code: boolean doSth = true; void setup(){ } void draw(){ if(doSth){ //-> if doSth == true println("I'm doing somthing!"); //put your animation here } else println("I'm bored"); } void keyPressed(){ if(key=='d') doSth = true; else doSth = false; }
