Space Game Story
This is a space ship shooting game. The player controls a space ship that
moves left and right across the bottom of the screen. There is an asteroid that
bounces around the screen. To get points you must shoot the asteroid. When you
have 100 points you go to the next level. If the asteroid hits you, you lose a
life. When you have lost all your lives the game ends.

Extension 1: Ending the Game More Gracefully
You will have noticed that the game just ends abruptly when
you have lost all your lives. Rather than choosing 'End
the Game' when you have used all your lives, choose 'Jump to
Frame'. Put in a frame that has some text saying 'Game
Over'. Add a score object on it, so you can see the final
score. Add an event for this frame 'On mouse click' and
End the Game.

Extension 2: To make an explosion when the bullet hits
When the bullet hits the asteroid, we will set a counter to
be 0. Every second the value will count up by 1.
When it reaches 3, we will destroy the explosion. (So the
explosion will last 3 seconds before it is destroyed.)
Go to the Event Editor
For Bullet collides with Asteroid Event:
Create an explosion at (0,0) relative to asteroid
Set the alterable value A of asteroid to be 0 (This is
the counter, set to 0)
Add in a new event: Every 1 second, increase the alterable
value A of the asteroid by 1.
Add in a new event: Test if alterable value of A = 3, then
destroy Explosion
|
Extension 3: To slow down shooting
To slow down shooting so the player has to wait 3 seconds
before they can shoot again:
Set the alterable value of the space ship to 0 when it shoots.
Add in a new event: Every 1 second, add 1 to spaceship’s
alterable value
Modify Upon pressing space bar event to add a new condition: If
alterable value A of space ship > = 3
