The game starts by killing the first type of enemy. I have a condition that when a number of enemies are dead it will switch to a different scenario(Shop) where they can purchase weapons, I have this "back button"(actor) that when it is clicked. It will switch back to the myWorld. but instead of killing the same type of enemies I want to spawn Golem(actor) instead. This is the code I have in myWorld ,, This is like my main level.

It will switch to a new MyWorld -- not back to the same one prior to going to shop (see line 4 in Shop). However, that may not be bad, since you set its current level to 2. Why did you exclude Back class codes from what you gave? Please provide.

Hey Dan it's me again. Here's the code for my Back(actor), Im also using this to go back to the main menu of the game. and the other use for this is with the Shop. What i have in my mind is the player will click this button to go back in the game, not with the same enemy but a new one. Basically like going to the next level.

With the current code I have, It only spawns the ghost and not the golem, but in my code in the Shop, it should set the "currentLevel" to 2 and spawn the golem right? also a similar question, i have a class that holds my score and the money(Counter class). how can i create a new scenario without losing that value? I want to keep track of those through out the game.

By "new scenario", you mean "new world". Better would be to return to the same world. Maybe you should take a look at my World Changing Demo scenario.

The world retains the current level. Increment it when level is complete (immediately -- before going to shop. ?? in switchToShop method ??).

Hey Dan just a follow-up, So I did the increment before going to the shop which is works perfectly. I can play the game form level 1 to the last level. But the problem now is when I reset greenfoot my world stays at the last level instead of going back to the beggenning.
