Integrating the UI into the game

Now that we have our enemies ready to challenge the player, let's integrate the UI that we have created in the previous chapter into the game.

In particular, we are going to see how to integrate the Lives Counter and the Money Counter since they are the two core gameplay elements.

This happens in the following way: the enemy triggers a function in the Game Manager when it has reached the end, and the Game Manager updates the number of lives in the Lives Counter.

Therefore, let's start by opening our GameManagerScript and adding another variable. This is required to store the LivesCounterScript reference, so that we can have access to the lives of the player:

private LivesCounterScript livesCounter; 

To get the reference, we can set the variable inside the Start() function:

  void...
