body_enter with 3D objects

Question

I can't make this work! :(

So my goal is to simply detect the other colliders that gets in my trigger.

I modeled a 3D Cone that will act like a "spray" weapon to anyone that stands in it.

---

The code is located in the root obj of the cone:

So I tried the code as an Area object (PS: the "#" are there to avoid errors in that case):

 extends Area

func _ready():
    #set_contact_monitor(true)
    #set_max_contacts_reported(5)
    connect("body_enter", self, "_on_body_enter")
    pass

func _on_body_enter(body):
    print (body.get_name())
    pass

and as a RigidBody instance (Yes, I changed the root obj type):

extends RigidBody

func _ready():
    set_contact_monitor(true)
    set_max_contacts_reported(5)
    connect("body_enter", self, "_on_body_enter")
    pass

func _on_body_enter(body):
    print (body.get_name())
    pass

In either ways, nothing is printed in the output!!

Are there some important things I am missing?:

• Do other colliding objects needs a trigger collision shape?
• Does bodyenter works in process or fixedprocess?
• Does it work at all on Area instances or only works as RigidBody?

Help me plz, Math

Answer 1

You need an Collision Shape as Child of your Area.
The collision shape has a property, Shape, and there is where you can load your Cone
