To finish off all the attack moves for the boss, let's create a third attack pattern script.
For this attack pattern, we are going to use an interesting mathematical formula called a sine wave. You might recognize this pattern from mathematics or from a radio wave readout. This pattern causes the sprite to move up and down in a regular curved wave pattern.
It looks very good and can be quite hard to dodge if you're not careful. It serves as a perfect "killer" move to close this part of the tutorial with.
This third attack pattern script starts and closes in exactly the same way as the other two. We start with receiving the message pattern3 and close by picking a new random pattern from the list, as follows:
For this pattern, we also use set rotation style <left-right>, since it looks better when the sprite is facing straight ahead.
We then use glide 1 secs to x: () y: () and set it to the middle-right corner of the screen, filling...
