Thread: Help with bouncing on a panel

Here I made a code that takes an object, in this case an enemy ship, and move it to the left. I want that object to bounce to the right when he touches the left side of the screen and bounce to the left when he touches the right side of the screen.

What I get when I run the program is the enemy ship moving to the left and it stays on the left side of the panel without bouncing to the right.

graphicsMan.drawEnemyShip(enemyship, g2d, this);
 
 
			if(enemyship.getX() - enemyship.getSpeed() >= 0)
 
			{
				ship.translate(-enemyship.getSpeed(), 0);
 
			}
 
			if (gameLogic.leftBorderCollision()){
 
				enemyship.translate(enemyship.getSpeed(), 0);
 
			}
 
			if (gameLogic.rightBorderCollision()){
 
				enemyship.translate(-enemyship.getSpeed(),0);
 
			}
 
In another class named GameLogic I have the collision methods defined as:
 
 
        public boolean rightBorderCollision(){
 
		if(enemyship.getX() +  enemyship.width >= 500){
 
			return true;
		}
		return false;
	}
 
	public boolean leftBorderCollision(){
 
		if(enemyship.getX() <= 0){
			return true;
		}
		return false;
	}

The method that controls movement is the translate method. For example if I put

enemyship.translate(enemyship.getSpeed(), 0);

The enemyships move to the right drawing him self 3 pixels to the right each time that (1/60) second pass.

The collision detecting methods recognize each time the ship touches the right or left panel of the screen.

If the ship touches the left side of the screen in another words if the location of the ship is negative in the x axis I want the ship to turn in the other direction (right). I did a System.out.print inside the left collision method and the console displays the System.out.print, so the method detects the collision but I am not sure if the changing direction method works.
