I am making a maze game and I am having trouble getting my ball to stop and not go through the wall when it hits it. Here is my attempted code.


public class Ball extends Animal
{
    
    private boolean moving = false;
    
    /**
     * Act - do whatever the Ball wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public void act() 
    {
        checkKeypress();
    }  

    public void checkKeypress()
    {
        int x = 3;
        moving = false;
        if(moving = false)
        {
            
            if (Greenfoot.isKeyDown("left"))
            {

                move(-x);
                turn(-5);

            }
            setRotation(360);
            if (Greenfoot.isKeyDown("right"))
            {

                move(x);
                turn(5);

            }
            setRotation(90);  
            if (Greenfoot.isKeyDown("up"))  
            { 
                move(-x);

            }  
            if (Greenfoot.isKeyDown("down"))  
            {
                move(x);

            } 
            setRotation(0);
        }

        if(canSee(HWall.class)) 
        {
            moving = true;
        }
        
        if(!canSee(HWall.class))
        {
            moving = false;
        }
        
        if(canSee(VWall.class))
        {
            moving = true;
        }
        
        if(!canSee(VWall.class)) 
        {
            moving = false;
        }

        if (moving = true)
        {
            x = x*(-1);
        }
    }
}
