Fix the Score
You will have noticed that when you hit the clown with a bullet, the score
goes to 5, but then it doesn't get any higher.
Double Click objEnemy to open its properties. Click the collision with
objBullet event.
Double click the Set the Score to 5 Action
Tick the Relative check box. (Relative means that the score will be 5
more than it was before)

Look at the Step Event
The step event occurs every step of the game, usually 30 times
every second. In the step event you put in actions that need
to happen continuously. In this case we are using it to check
the y position of objEnemy. If y>460 it means the enemy has
got to the bottom of the screen, so the game is over.
Double click the Step Event for objEnemy.
Look at the block markers. If the expression is true (If
y>460), then every action between the block markers will be carried
out. |

Make the Clowns Look Scary as they Advance
As the clowns get closer to the bottom of the screen, we will change their
appearance by changing the sprite.
Open the Step Event for objEnemy

- For the expression use y>240. If y>240, the clown will be halfway
down the screen.
- From the main1 tab, put in a 'Change Sprite' action
- Choose sprEnemy2
Test your game.
Repeat with another action for when y>360; change the sprite to
sprEnemy3.
