How should I change it so the image displays on top of the black background?

To display it "on top", you would use an actor. To display it "on", draw the directions image onto the background of the world.

<< Code Omitted >> I want to have a little bit of time between the image of the lock getting changed and the lock getting deleted, so you can actually see the opened Lock.

Add an int timer field to the KeyLock class. Set it to some positive value (30-60 maybe) when opened. Use act to count down the timer and upon reaching zero, remove the actor.

Greenfoot exercise 9.69

Replied to by danpost, over 6 years ago:

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

The condition on line 81 will always be true (that is, unless size is less than or equal to zero -- which would be never). I think you should be asking if the size is greater than 16 or not.

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

Appears okay. And, finally, your Bullet class? It would seem like that is where the collisions are detected.

How can i have a player to move a certain amount of steps in order to finish the game?

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 add an int field for the player. Increment it each time it moves. When object is reached, check its value for win/lose.
