Apply Shader to one player only

[errant forge]

Well, i want my shader to be applied to just the player that is not the leader of the group, so that way, the player you are not controlling is on B&W color. But it just applies to both players and i don't know what im doing wrong :/

I have a Player class with the node tree shown in the screenshot and this code in the _process() function:

func _process(delta):
# DEBUG
var leader = MainScene.current_player
if !self.is_leader:
debug.text = " --- DEBUG ---\n" + "leader: " + str(self.player_name) + "\n" + "team: " + str(self.team) +" \n" + "can_team: " + str(self.can_team) +" \n" + "distance: " + str(round(self.global_position.distance_to(leader.global_position))) + " <= " + str(distance_between) + " : " + str(self.global_position.distance_to(leader.global_position) <= distance_between)
animacion.material.set_shader_parameter("saturation", 0)
else:
animacion.material.set_shader_parameter("saturation", 1)
debug.text = " --- DEBUG ---\n" + "leader: " + str(leader.player_name) + "\n" + "team: " + str(leader.team) +" \n" + "can_team: " + str(leader.can_team) +" \n" + "distance: " + str(round(MainScene.other_player.global_position.distance_to(leader.global_position))) + " <= " + str(distance_between) + " : " + str(MainScene.other_player.global_position.distance_to(leader.global_position) <= distance_between)

The shader is working fine, its this one i found on Internet:

Setting a shader parameter will modify the material itself, so if your players all share the same material it will modify all of the players

In the case of 2D nodes instanced shader uniforms are not implemented yet so you will have to make a second material you can swap out the normal one with

So something like

@export var bw_material : Material
@export var color_material : Material

func _process(delta):
  if not self.is_leader:
    player.material = bw_material
  else:
    player.material = color_material

although I would recommend trying not to swap the material in the process function, as that gets called every frame

you could make a signal for when is_leader changes or use a setter function for it

Hahaha, thank you!

Thanks for your help! I put the shader change out of the process too, thanks for the advice
