[SOLVED] Multiplayer crossplatform Windows-Android VR cameras

Mikerhinos

Hello,

I'm trying to do a little test of a FPS, multiplayer and crossplatform between Windows and Android in VR mode. My problem is cameras look messed up : if I launch game in solo mode, all is working fine, with normal FPS view on Windows, and VR view on Android. Moving and turning head works too. BUT, as soon as I launch a LAN game, being Win+Android or Win+Android+Android, it looks like the cameras are all on player 1 (their rotation is independant from each other though), moving looks like it still works, it's just the cameras being all on player 1. I'm pretty sure that it's a make_current() or clear_current() thing but I can't find how.

What would be a typical structure to manage cameras on masters ?

My player script _ready() looks like this :

func _ready():
	if OS.get_name() == "Android":
		camera = get_node("Rotation_Helper/ARVROrigin/ARVRCamera")
		var VR = ARVRServer.find_interface("Native mobile")
		if VR and VR.initialize():
			get_viewport().arvr = true
			get_viewport().hdr = false
			OS.vsync_enabled = false
			Engine.target_fps = 90
	else:
		camera = get_node("Rotation_Helper/camera")
	if is_network_master():
		camera.make_current()
	camera.visible = true
	Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)
	puppet_pos = translation

I modified the function like this to ensure all other players on local game have their camera disabled :

func _ready():
	if is_network_master():
		if OS.get_name() == "Android":
			camera = $Rotation_Helper/ARVROrigin/ARVRCamera
			var VR = ARVRServer.find_interface("Native mobile")
			if VR and VR.initialize():
				get_viewport().arvr = true
				get_viewport().hdr = false
				OS.vsync_enabled = false
				Engine.target_fps = 90
		else:
			camera = $Rotation_Helper/camera
		var players = get_tree().root.get_node("Level/players")
		for _i in players.get_children() :
			_i.get_node("Rotation_Helper/camera").clear_current()
			_i.get_node("Rotation_Helper/ARVROrigin/ARVRCamera").clear_current()
		camera.make_current()
	camera.visible = true
	Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

But still the same problem :anguished: : If I launch a game with 3 players, they spawn at their right spot, they move independently, but they have all their camera on player 1...

For anyone getting there via Google, I fixed it by deleting (queue_free()) all cameras but the one on is_network_master(), thanks derkork on Godot Discord channel for helping me figuring out :+1:

(all other players are just some sort of NPCs in your local game, and don't need a camera).
