How do I link between the Player, the mob and the HUD

Updater3000

Hello Godot community hope you're doing well.

So I've been learning and working at the same time on a project, so far I've learned many things form my previous posts and tutorials that I found in Youtube and internet, recently I discovered GDquest and got charmed by his way of explaining things and followed his Godot Engine tutorials, anyway I've come here because I've hit a wall.

In my main scene I have a movable character with a HUD, and a monster, what I can't figure is how to change the value change when the character hits the monster, I don't even know how to check if a node collides with another node.

As always thank you for your help and time.

Thanks for your reply ser, but yes I know how to check for collision but when I use is_colliding() it is processed whenever the object is colliding but in my case I want to check collision only between 2 specific objects (which is the player and the mob) and ignore the rest (even if the player is colliding with the ground), and when they collide the value of the progress bar should decrease.

EDIT : Ok, I did the progress bar part I added a line like this to my player script, just to check it, I added a func named it take_dmg(dmg) in the HUD script and whenever my player jumps the func is called get_parent().get_node("CanvasLayer/HUD/").call("take_dmg", 5)

I only need to find a way to check collision or a thing of some sort between 2 specific objects.

I read the documentation on Area2D but honestly I need a live example on how to use it, I am not that good in coding in Godot.

Thanks.

There's a bunch of different ways to check what something collided with. You could check the collider's name with get_name(), you could check if is_in_group(), or you can preload the object's script and check if it extends that script.

Whenever you have a collision and something happens, like damage, you need to decide which way it's going to go. If you want the player to take damage when they walk into an enemy, you can either have the player check its collisions and take damage if it hits an enemy, or you can have the enemy check and if it hits a player it damages that player. Depending on your project one way may be easier than the other. Or it may not matter, but you'll want to be consistent so you don't double-up damage or something.

If you give the player its own collision group, sometimes you can get away with using Area2Ds that only respond to that channel so you know that all body_enter(body) signals will be the player and you don't have to do any other checks.
