I am in the process of making a maze game. I am new to Greenfoot. One problem I encountered while trying to make my maze game is that the player can go through walls. How would I stop this? Thanks. Please reply fast!

Show the code or no one can help. Greenfoot has good collision detection so thats one strategy.

    public void act() 
    {
        if (Greenfoot.isKeyDown("left"))
        {
            setRotation(180);
            move(4);
        }
        
        if (Greenfoot.isKeyDown("right"))
        {
            setRotation(0);
            move(4);
        }
        
        if (Greenfoot.isKeyDown("up"))
        {
            setRotation(270);
            move(4);
        }
        
        if (Greenfoot.isKeyDown("down"))
        {
            setRotation(90);
            move(4);
        }
       
    }
There's the code. Thanks for the fast reply!

Check out the Greenfoot documentation for the Actor class. Find out what method you might use to determine if the move made will1 make the actor go into/through a wall. Create a query and action combination to prevent going into/through the wall.

to stop an Actor from passing through walls, first create a variable to store x and y: private int x; private int y; the method is: public void stopAtWalls() { if (getOneIntersectingObject(Wall.class) != null) { setLocation(x,y); } else { x = getX(); y = getY(); } }
