If you follow the act method step by step, you will get this: Block 1 (lines 18 through 21): removes the actor from the world if off sceeen; Block 2 (lines 23 though 26): removes any center-intersecting player; Block 3 (line 27): moves actor left; If the actor is removed from the world by block 1, then neither block 2 nor block 3 can execute properly. Both 2 and 3 require that the actor be in the world. When you execute 'getWorld().removeObject(this)', the hidden 'world' field from the Actor class for that actor is set to 'null'. No in-world operations can be exec

It looks like you need to create a list of pairings. However, since you already know that both sides of the pairings are one-character strings, you can use a simple String object to store the pairings. Start with: <Code Omitted>as a field within the class (declared outside of any method). Then, as each pairing is entered, add the pair to the String object: <Code Omitted>To apply the pairings to Label, use something like this:

The 'if' statement is, in essence, a blocking statement. If the condition is 'false', the code block will not execute. You would say 'if some set of conditions are true, execute the following code'. I would suggest using 'else' in this matter ( that is: 'if (dy == 0) {} else { run space command }' ), and, in fact, that is exactly what you could do. The code within the empty curly brackets ( '{}' ) could be 'run left/right command':
