Godot 4 Movement and Health System with Progress Bar Tutorial

To add movement to your player there is no better way than the one described on the official documentation Godot Docs (click to open on ne window) once you have your basic player set up, we can get into the good stuff.

To add health to a player with a health bar in Godot with gdscript, you can follow these steps:

Create a health variable: First, you need to create a health variable that will keep track of the player’s health.

This can be done by adding a new variable to your player’s script.

var health = 10

Create a Health Bar: Next, you need to create a health bar that will display the player’s current health.

You can do this by adding a new ProgressBar node to your scene which will be the texture for the health bar.

You can set the Max health value of the bar on the Max Value field, and the Step field is the amount that is subtracted from the health value.

Update the Health Bar: You will need to update the health bar every time the player’s health changes.

To do this, you can create a function that updates the health bar based on the current health variable.

func update_health_bar():
$HBar.value = health 

This function sets the value of the health bar to be the current health divided by the maximum health (in this case, 10).

Reduce Health: When the player takes damage, you need to reduce their health. This can be done by subtracting the damage amount from the health variable.

func take_damage(damage):
health -= damage

This function reduces the health variable by the amount of damage taken and then updates the health bar to reflect the new health value.

Check for Death: Finally, you will need to check if the player’s health has reached zero, and if so, take appropriate action such as displaying a game over screen or resetting the level.

func _process(delta):
if health <= 0:
# Player has died
# restart scene       get_tree().reload_current_scene()

In this example, the _process function is used to continuously check if the player’s health has reached zero. If it has, you can add game over logic to this section of code.

By following these steps, you can add health to a player with a health bar in Godot.
