I want that the "Mans.class" is in front of the "Objects.class", because ussully the "Objects.class" is before the "Mans.class" This is my Mans code. import greenfoot.*; public class Mans extends Actor { public int ySpeed; public int groundLevel=489; private boolean pressed; public void act() { boolean onGround = false; ySpeed++; setLocation(getX(), getY()+ySpeed); // at ground level if (getY() > groundLevel) { ySpeed = 0; setLocation(getX(), groundLevel); onGround = true; } // hitting box Actor object = getOneIntersectingObject(Objects.class); if (object != null) { int yDir = (int)Math.signum(ySpeed); setLocation(getX(), object.getY()-yDir*((object.getImage().getHeight()+getImage().getHeight())/2+1)); ySpeed = 0; if (yDir > 0) onGround = true; } // jumping if (onGround && Greenfoot.isKeyDown("up")) ySpeed = -15; // firing weapon if (pressed == Greenfoot.isKeyDown("space")) { pressed = !pressed; if (pressed) getWorld().addObject(new Weapons(), getX()+80, getY()-25); } //die if (this.isAtEdge()) { this.removeTouching(Objects.class); this.setImage("Death_Man.png"); this.setLocation(150, 520); Greenfoot.playSound("game-over.wav"); Greenfoot.stop(); //Here I want to put the "Mans.class" in front of the other Objects. } } }
