i'm trying to make a recreation of the 8-bit super mario bros for a school project. I've worked out the movement, jump, and gravity. But when i want my character to land on my platform, it falls right through. How do i fix that?

Cannot fix unseen code. Please provide Mario class codes (at minimum).

You should probably check out my Jump and Run Demo w/Moving Platform scenario. Just run it and click the appropriate code button along bottom to view the codes.

It would be in the moveVertically method of the Who class.

It still has the original broken code. I need to see your attempted copied code -- to see how you tried to implement it.

so i figured out how the platforms work but that caused my characters to lose the ability to jump 
 int vSpeed = 0;
    int accel = 0;
    private int gravity;
    public void act() 
    {
        checkFalling();
        fall();
        gravity--;
        setLocation(getX(), getY());
        
        checkForJump();
        jump();
        
        
        if(Greenfoot.isKeyDown("left")) {
            move(-3);
        }        
        if(Greenfoot.isKeyDown("right")) {
            move(3);
        }   // Add your action code here.
        
    }  
    public void jump()
    {
        if(Greenfoot.isKeyDown("up"))
        {
            vSpeed = -10;
            gravity = 20;
        }
        else
        {
            vSpeed = 0;
        }
    }
    public void fall()
    {
        
        setLocation(getX(), getY() + vSpeed - gravity);

    }
    public void checkForJump()
    {
        if(Greenfoot.isKeyDown("up"))
        {
            vSpeed = -10;
            gravity = 20;
        }
    }
    
    public void checkFalling()
    {
        if(!isTouching(Ground.class))
        {
            vSpeed = 0;
            gravity = 0;
        }
        
    }

That code is nowhere close to what I have in my demo.
There are more replies on the next page.
