Question

Hello what’s the best way to trade info between two scenes? in my game I’m trying to make an object (that’s in another scene) that when hit by a raycast restores the players health or gives them ammo etc and updates a progress bar node. I’ve tried to use classes but i cant seem to get it to work.

Let the object scene emit a signal that player (or game logic script) can connect to.

You can use groups for that:

# On your player script:
func _ready() -> void:
    add_to_group(“player“)

So from any node you can use get_tree().get_first_node_in_group(“player“) to get a reference to your player node. You can also direct call any function from your player script using get_tree().call_group(“player“, “function_name“, arg1, arg2, etc) so you can call a function that give ammo/health to the player.
