Can you explain what line 5 does though?

Can anybody check my code? Code is between 77 to 89.

code for more classes can you check it. << Code Omitted >>

I have a player and they can move 1 step by pressing an arrowkey. Now i want them to reach an object and collecting it BUT with a certain amount of given steps. Lets say you start in the bottom left corner and the other object is somewhere in the upper right corner. Now you have to reach that object with exactly 15 steps e.g. How can i make such a counter?!

Just to be clear, an actor with zero rotation is considered to be facing (or turned towards) the right. If the image given the actor is not one that naturally "faces" right, then you will need to do something extra to make it appear properly. Let us say that you have a rocket image which "faces" up as it would when in a landed orientation. You could set it as the default image and change its orientation in the constructor of the class:

You are calling two methods, each which could remove the actor from the world (lines 12 and 13). Neither of these methods can execute properly if the actor is not in the world (one uses getOneObjectAtOffset and the other isAtEdge,, both requiring the actor be in a world). Regardless of the order these methods are called, if the first one removes the actor, the second one will fail. There are two main ways to avoid this dilemma. One is to not remove the actor is those called method, but have them return a boolean value indicating the "to-remove" state
