RigidBody2D Contact Monitoring

Knight_XAura

Why does does this state that it will emit signals when contacting other RigidBody2D's when it also collides and emits signals when colliding with at least CharacterBody2D's and StaticBody2D's. is this an error in documentation? Or is there something I'm not seeing somehow? It clearly states this and all my bodies queue_free() them selves upon collision and without this on my bullets don't queue_free() when colliding, but with it on and Max Contacts set to 1 they will now queue_free()

According to Godot docs
In the signals' descriptions, it is said that the signal is emitted when contact with another PhysicsBody2D occurs.
This includes any node type that inherits it, like RigidBody2D, CharacterBody2D, and StaticBody2D.
You probably need to check the body type in the function you connect the signal to.

func _on_body_entered(body):
  if body is RigidBody2D: # or whatever check so that not every body just gets queue freed
    queue_free()

I don't think you understand. If you have a rigidbody and don't turn on contact monitoring and use the Body Entered Signal, nothing happens with any of my collisions. If I turn on Contact Monitoring and up the max contacts to 1 (or higher) even though this states it is meant for contact with other rigidbody2d's, it actually works for all physicsbody2d's

If I turn Contact Monitoring on my RigidBody2D none of my collisions get detected and instead it just bounces off or loses most if not all it's velocity rather then triggering it's body entered signal code which is set do the same thing no matter the body that enters, just queue_free()

I hear you
The docs say on contact_monitor:

If true, the RigidBody2D will emit signals when it collides with another RigidBody2D.

Note: By default the maximum contacts reported is set to 0, meaning nothing will be recorded, see max_contacts_reported.

However in the signals, it says this:

body_entered ( Node body )

Emitted when a collision with another PhysicsBody2D or TileMap occurs. Requires contact_monitor to be set to true and max_contacts_reported to be set high enough to detect all the collisions. TileMaps are detected if the TileSet has Collision Shape2Ds.

body the Node, if it exists in the tree, of the other PhysicsBody2D or TileMap.

The signal needs contact monitor and max contacts to be set, in order to be emitted when a collision with another PhysicsBody2D occurs.
And in contact_monitor it says RigidBody2D instead. It is what it is
I don't understand whether it is intentional or not. But it is misleading.
And I didn't understand what your problem really is, and I am not sure I understand it yet.

The signal is not being emitted even though you turn contact_monitor to true and set max_contacts_reported bigger than 0? I have no idea of a solution.

But if the signal gets emitted with every physics body, you can check what this body is as a solution.

If the signal gets emitted with every physics body but not with rigid body, I also don't understand how is that happening.
I hope someone has a better answer.
