| Part 2) Animating the Asteroid |
 |
|
| Step 7. |
| In the previous part we formed an asteroid, using 4 instances of the rockMc. In this 2nd part we're going to animat the rock destructing, which will be triggered when a missile from the ship hits it. |
|
|
|
| |
| Step 8. |
| Highlight frame 40, of all 4 layers, and then create a key frame (F6) for each of them. |
|
|
|
| |
| Step 9. |
| Zoom out to 50% and move each rock, on frame 40, away from its original position. The rockMc's will need to move outside of the screen area, so you may need to come back to this later, if they don't reach that far. |
|
|
|
| |
|
|
| Step 10. |
| Highligh a frame of all 4 layers, right click and choose 'Create Motion Tween'. The rocks should now move, as you move the timeline play head from left to right. |
|
|
|
|
| Step 11. |
| The rocks need to stay together, until the asteroid is hit, so we need to create a stop() action on frame 1. I've done so on a 5th layer called script. |
|
|
|
|
| Step 12. |
| When the asteroid is hit, the animation will play, but we need to create another stop() action at frame 40, so that it doesn't play again. We also need a way of knowing when the animation has reach frame 40, so restart variable is set to 'true'. |
