When I click on World (w) the code (w.addObject(new Boomerang(), 100, 300);) makes it crash. I am sure that that line is the problem because the code didn't crash when I commented it out.
context: code is in Actor subclass called Items and Boomerang is a subclass from items.
public void act() { if(boomCheck == 0) { throwBoomerang(); } } public void throwBoomerang() { //Zorgt ervoor dat je een boomerang kan gooien. if(Greenfoot.mousePressed(w)) { Minion2X = minion.MinionX; Minion2Y = minion.MinionY; w.addObject(new Boomerang(), 100, 300); boomCheck = 1; } }
