05. We’ve now got Madame Octopus happily moving around the screen in response to the arrow keys. The next stage is to add some objects for her to avoid. We’ll make use of the bubble movie clip that we used last month. Locate the bubble MovieClip in your library, right-click (Ctrl + click) on it and choose Duplicate. Name the duplicate ‘evilBubble’, and again tick Export for ActionScript, giving the MovieClip an identifier of ‘EB’ and a class of ‘EB’. If you didn’t complete last month’s tutorial, open the file EB.as from the cover CD.
06. Double-click on the evilBubble symbol in the library, and remove all but the first frame of the timeline by highlighting the frames, right-clicking and selecting Remove Frames. Delete the motion guide layer, then reposition the bubble so that its centre aligns with the origin crosshairs on the stage. Select the bubble and use the Tint colour effect to give it a colour.
07. The evil bubble doesn’t yet appear on stage; it’s in the library waiting to be used. We’re going to create lots of evil bubbles using ActionScript. Go to File > New, select ActionScript file, and save the resulting document as EB.as.
