- Create Instance: object “enemy2 bullet”, x = 0, y = 16, relative
starts firing bullets (down, from center of the plane).
Main Plane Hit
Go into your myplane object and add a Collision with enemy2 bullet event. If the main plane gets hit, it gets a bit weaker, loses some health.
- Set Health: lose 5 (make sure relative!)
- Destroy Instance: other = enemy2 bullet
Test it out.
- Do the enemy2 planes shoot bullets?
- Does the main plane’s health go down?
Main Plane Destroyed
Once the main plane has lost all its health, it should blow up, be destroyed in a big explosion.
Big Explosion
Go into the object explosion2 object and add an Animation End event with the following actions..
- Destroy Instance (self)
- Sleep – to make sure the exploding sound is finished, 1 sec.
- Create Instance: create a myplane in the same spot.
- Set Lives: lose a life (relative)
No more Health
When the main plane has No More Health, we want it to turn into a big explosion.
- Change Instance: if no more health, want to change object: myplane into a big explosion, explosion2
- Set Health: set it back to 100
Test this out – make sure your plane explodes when you’ve hit too many enemy planes. When you run out of health, does your plane explode? do you lose a life?
Keep your game open in the Enemy 2 testing level to get checked off…
