To make the game more fun the sheeps are instantiated with random speeds between a defined range.
Basically the hay machine can enter a boost mode where it doubles the speed and fire rate. We can activate this mode by holding the shift key. To balance the mechanic it comes together with a resource meter that we will have to manage properly to keep up with the sheep.
I added a live system, every time one of our sheep die we lose one life, it is indicated in the UI by 3 sheep sprites.
To add a goal to the game I added a score system, each time we hit a sheep a punctuation will be added to our score depending on the speed of the sheep. The goal of the game is reaching the highest score possible.
I added interactivity to the title screen provided, so we can reset and start our game.
Simple, when we lose all of our lives we get sent to the title screen were we can restart our game.
To make all the programming more simple I added an event system that I also used in the previous practice. Making the code more robust and decoupled. Also it really helps with the pain of dragging multiple gameObjects through the hierarchy.
