Hello I got a problem. When I let my Player climb a ladder it works fine, but sometimes he glitches like for example falling out of the world or fall surprisingly fast, when I go off the ladder... Player class:

{
private int vSpeed = 0;

public void act
{
if(isTouching(Ladder_Long_Function.class) == false)
fall();
if(isTouching(Ladder_Long_Function.class) && Greenfoot.isKeyDown("up"))
        {
            setImage(myGif3.getCurrentImage());
            setLocation(getX(), getY()-5);
        }
}
public void fall()
    {
        setLocation(getX(), getY() + vSpeed);
    }
}

Line 6 should be:

if(!isTouching(Ladder_Long_Function.class && !isTouching(Floor.class))

or

if(!isTouching(Ladder_Long_Function.class && getY() < your floor coordinate)

"!" before function is the same " == false" after fuction.

Thank you for your answer. Unfortunately a syntax error message shows up: "bad operand types for binary operator '&&' first type: java.lang.Class<Ladder_Long_Function> second type: boolean" What can I do to fix that?

Sorry, my bad. I've done a mistake in my code. This is right

if(!isTouching(Ladder_Long_Function.class) && !isTouching(Floor.class))
