Hello, I have been trying to make a body bounce when bouncing off an edge in Newton's Lab 3. This is to make multiple enities when they touch the edge, change colour. Here is the current code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | private void bounceAtEdge(){ if (getX() == 0 || getX() == getWorld().getWidth()-1) { setLocation((double)getX(), (double)getY()); getMovement().revertHorizontal(); accelerate(0.9); changeColor() } else if (getY() == 0 || getY() == getWorld().getHeight()-1){ setLocation((double)getX(), (double)getY()); getMovement().revertVertical(); accelerate(0.9); changeColor() } }public void changeColor(){ int g = Greenfoot.getRandomNumber(255); int r = Greenfoot.getRandomNumber(255); int b = Greenfoot.getRandomNumber(255); image.setColor (color); }/** |
