Powerups: Making them modular

Since I plan on having more than just 1 power-up, I will make it something a bit more modular.

Making it modular, means I don’t have to create a new script for each and every variant I need. Instead, I can use one script that holds enough information for it to indicate what powerup it is.

Doing it this way, I only have to change a variable and replace the sprite!

I opt to use IDs to represent the different kinds of powerups.

Now I simply need to pass the ID of the powerup to the Player when it’s collected. The player script then handles how that powerup should affect it.

public class Player : MonoBehaviour
{
 //....
    private void ActivatePowerup(int powerupID)
    {
        if (powerupID == 0)
        {
            StartCoroutine(TripleShotRoutine());
        }
        if (powerupID == 1)
        {
         // increase speed routine
        }
    }
}

Now we have an easier way to handle powerups, that is extendible.
