getoneintersectingobject(name.class) what does it do? Does it check whether it intersect/touch the name.class?
Yes, but there is more to it than that. It returns a reference to an intersecting Actor object of the type (?.class) given. If no actor of that type is found to be intersecting, it returns a null value.

I removed the entire platform since it was useless and made my actor go the other way if it reaches certain coordinate.

To do this I have two actor classes, one of the classes has the normal image and the other has a mirror image of the first class.
A better way is to use just one actor and change its image when needed.

has anyone an idea how to punch with an actor

You will need a method that determines if an enemy is in front (one that returns a boolean, or true/false, value). You will also probably need a boolean field that tracks the state of the punch key. If state of key changes to the down state, then punch and check for enemy in front. Have enemy, when being punched, either lose hp or be removed.

We have 4 levels (DemoWorld, Maze1, Maze2, Maze3) and we want to advance a level every time cheeseCount == 2 (change to Maze1), cheeseCount == 52 ( go to Maze2) and cheeseCount ==102 (go to Maze3) The program changes to Maze1 after all the cheese is collected in DemoWorld but after we enter aMaze1 and collect all the cheese, the world doesn't change..... << Code Omitted >>
Add a second condition to lines 37, 40 and 43 that requires the specific type of world (DemoWorld, Maze1 and Maze2).

Check if my Actor is touching an edge

Replied to by Super_Hippo, 9 days ago:
If the size of the world is 1300×900 and you don’t allow objects to be outside the visible part of the world, then the object is inside the rectangle defined by the following four points: (0|0), (1299|0) (0|899), (1299|899) It will never be at x=1300. And even if it could be there exactly at (1300|450), it might not be very much fun to find this exact cell to move forward.

True. It can still be confusing to use the same name.
I presumed you knew that, but just overlooked it. I only stated that for Roshan123's benefit.

"incompatible types: greenfoot.Actor cannot be converted to Figur" Error appearing when trying to use Figur figur = getOneIntersectingObject(Figur.class)

By Lorenz123, with 4 replies.
Last reply by danpost, 10 days ago:
Line 3: getOneIntersectingObject returns an object (or 'null') typed as an Actor object. The compiler will not assume it is a Figur object and "blindly" place the object in a variable that is to specifically reference a Figur object. You must tell the compiler that it, if it does exist, will indeed be of type Figur before it will place the reference in the variable. Hence the line Super_Hippo suggested.

so what should i write if anybody types THE QUICK BROWN it will show text according to the situation
If you are to "capture" that somebody types a phrase (not just a single key or key-combination), you will have to collect each keystroke individually (over time). This will require a String field and extensive code to build the string (or control the field's value) as the keys are being entered. As an alternative, you could use: <Code Omitted>
