| + | shoot() | ||
| + | </code> | ||
| + | * Add the shoot function | ||
| + | <code bash> | ||
| + | func shoot(): | ||
| + | if ray.is_colliding() and ray.get_collider().has_method("die"): | ||
| + | ray.get_collider().die() | ||
| + | </code> | ||
| + | * To allow strafing, change the ''If Input.is_action_just_pressed("ui_accept"):'' to | ||

| + | * Create a new function in the ui.gd script | ||
| + | <code> | ||
| + | function update_player_health(): | ||
| + | $health.text = str(get_parent().player_health) | ||
| + | </code> | ||
| + | * Add the function to the bottom of the _process() function in the ui.gd script | ||
| + | <code> | ||
| + | update_player_health() | ||
| + | </code> | ||

| + | <code> | ||
| + | func damage(): | ||
| + | player_health -= 10 | ||
| + | print(player_health) | ||
| + | if player_health <= 0: | ||
| + | queue_free() | ||
| + | </code> | ||
| + | * Add a RayCast3D to the guard scene | ||
| + | * Set Y = 0, Z = 5 | ||
| + | * After the ''play(shoot)'' line in the attack() function, add: | ||
| + | <code> | ||
| + | if $RayCast3D.is_colliding() and $RayCast3D.get_collider().has_method('damage'): | ||
| + | $RayCast3D.get_collider().damage() | ||
| + | </code> | ||
