Creating the player script

This is the moment we have been training for. We already know how to do this! So, start by creating a new script that is attached to the Player node:

1. Right-click the Player node and select Attach Script:

Figure 6.18 – Attaching a script to the Player node

2. In the dialogue that pops up, call the script player.gd:

Figure 6.19 – Calling the script player.gd

3. We’ll keep it simple for now and just add some code to manage the health of the player:

   extends Node2D
   const MAX_HEALTH: int = 10
   var health: int = 10
   func add__health_points(difference: int):
      health += difference
      health = clamp(health, 0, MAX_HEALTH)

   The clamp() function we use in the add_health_points() function takes a numeric value as the first argument and keeps it in between the second two numeric parameters.

This way, the health is always between 0 and MAX_HEALTH...
