1.) In this tutorial I will show you how to embed conditions into conditions.

2.) In this tutorial you need the following:
-Actions Panel
-2 or 3 symbols
-Your Properties Panel

3.) Sometimes when designing a game, you need to press keys, but you don't always want them to execute an action when its pressed.
you can specify exactly when you want something to happen by embeding an if statement inside of an if statement.

4.) This time name both of the symbols to get ready for action, in this case i named 1 "toad" and the second one "ghost".

5.) Then you can put this code in either movie clip, or you can put it in a seperate actionscript symbol, and you get the same result.

6.) When you hold down the UP Key, and When the 2 symbols are colliding, then a message will appear when you test it that says the String "Hello World".
