public void act()
    {
 
        if (Greenfoot.isKeyDown("left"))
        {
            moveLeft();
            Actor p = this.getOneIntersectingObject(Platforms.class);
            if(p != null)
            {
                moveRight();
            }
        }
        if(Greenfoot.isKeyDown("right"))
        {
            moveRight();
            Actor p = this.getOneIntersectingObject(Platforms.class);
            if(p != null)
            {
                moveLeft();
            }
        }
        if (Greenfoot.isKeyDown("up") && onPlatforms() && numJumps < 2)
        {
            jump();
            numJumps++;
 
        }
        hitSpike();
        hitGoal();
        if (onPlatforms())
        {
            vSpeed = 0;
            numJumps = 0;
            setImage(new GreenfootImage("Player.png"));
        }
        else
        {
            fall();
        }
        if (Greenfoot.isKeyDown("up") && numJumps < 2 && dbJumped == false)
        {
            doubleJump();
            dbJumped = true;
 
        }
    }
here is the code i have for movement and for double jump i am looking for a way to slow down how fast it registers a button click

You may want to increment numJumps on the 2nd jump (in your doubleJump method).

i put the numJumps++ in the method for double jump and now when i press the jump key it makes numJumps = 2. i am unsure as to how to make it only add one for the first jump and then if it is at 1 jump a second time and if its at numJumps = 2 fall down and then it will reset when it hit the platform

You may be able to delay the double jump so that it only happens near the apex of the first jump by adding the condittion:

if (vSpeed == -1)

do you mean replace the if statement for double jump with that condition? i am just confused to where i should add that condition.
