In this section, you'll add a shield to the player and a display element to the HUD showing the current shield level.
First, add the following to the top of the Player.gd script:
signal shield_changedexport (int) var max_shieldexport (float) var shield_regenvar shield = 0 setget set_shield
The shield variable will work similarly to lives, emitting a signal to the HUD whenever it changes. Save the script and set max_shield to 100 and shield_regen to 5 in the Inspector.
Next, add the following function, which handles changing the shield's value:
