1. Open “T2-touch.swf” for a preview of what can be accomplished from this tutorial.
2. Open “T2-touch.fla”, then Ctrl + L to open Library of the file.
3. Point to UFO1, press F9, type the following scripts:
4. Create a new layer.
5. Drag UFO2 to the stage. Make sure this UFO2 is in the new layer.
6. Point to UFO2, point to the “Properties” bar, type “movie1” in the “Instance Name” box.
7. Create one more new layer.
8. Point to the first frame of the new layer, press F9 and type the following:
9. Point to the “0” located on the left bottom of the stage.
10. Point to the “Properties” bar, type “dd” in the “Var” box.
That's all, run your movie (Ctrl + Enter) and check it all works. If not, go back though this tutorial and check you have not missed anything,

Let’s play game!
1. Download "T3-spacerock.fla" file
2. Click on the “play” button and press F9, copy the following to the action scripts space:
3. For this round, we make it easy, just copy the following scripts in 2nd frame of "Layer1":

4. That's all, run your movie (Ctrl + Enter) and check it all works. If not, go back though this tutorial and check you have not missed anything,
5. Here is an exercise for you. You are given graphics of stones and space ship below. Use PhotoShop to do the necessary adjustment and then replace them with those in the game.
