Area2D on_body_entered signal not firing for TileMap

JRileyH

I am having issues setting up collision with my autotile tilemap. Everything appears to be working pretty well even as a look over the scene .tscn file nothing seems out of place but the body_entered signal won't fire. I have a working area_entered signal firing just to sanity check myself and I have tried to strip it down to the simplest possible reproduction case.

# connected to area_entered signal
func _crash(area):
	print("%s - %s: crashed" % [name, area.name])

# connected to body_entered signal
func _bump(body):
	print("%s - %s: bumped" % [name, body.name])

I turned on collision visualization in the debug menu to be sure everything was setup properly

The signal icons are showing up in the editor in the proper places. Under the signal name for both area_entered and body_entered under the "Node" tab of the player. It also shows in the player script next to the crash and bump functions. The fact that the crash function is firing properly when i run into the Chicken sprite there and the bump is not when i run into the wall has lost me :anguished:

I'm semi-new to the forums and Godot so if I need to post more details, code, screenshots, whatever just let me know!

Zelta

checked the collisions layers are ok?

@Zelta This sounds like a feasible lead since I haven't heard the term yet. The area to are collisions are working and I never had to set collision layers for those so I am unfamiliar with the concept or how to check if the TileMap collision shapes might be on a different layer. Where do I inspect that?

Woah! New update. I began digging into the node attributes in the editor after what @Zelta mentioned and found that checking the box under Collisions labelled "Use Kinematic" to true has somehow got the collisions firing.. What is this setting and why would it not be default to true if its needed to interact with Area2D?

(Also I understand now what you mean by collision layers now. Yes they were on the same layer and that's a really helpful thing to understand moving forward to thank you are mentioning it Zelta)

Zelta

i think is your player firing self when u turn on kinematic and we are mixing things.

the kinetic body, staticbosy, area2d..... has collisions layer, lets say is in one layer but can look another. So u have to adjust what things player and npcs and tiles and whaterver u want interact with that collider or not. sorry my f english. maybe someone can explain this better.

other way u can do a simple area2d with a collision shape and then connect and script this (remember add player node to a group (Player) before)

func _on_Area2D_body_entered(body): if body.is_in_group("Player"): doyourthingbroh

and if you need tilemap colliders...
