Hello,
I have mesh-object planned as Kinematic Body
and I want to change the emission color in time
…emission colors ( color1 and color2 ) loops in time
i have a script but does not work
Thanks for help,guys

extends MeshInstance

var color_time

export (Color) var color1
export (Color) var color2 

var mesh 
var material = FixedMaterial.PARAM_EMISSION == Color(color1)

const PARAM_EMISSION = 3
#const PARAM_GLOW = 5

func _ready():
	set_process(true)
	mesh = get_node(".")
	mesh.set_material_override(material)
	color_time = get_node("/root/entity_test/entity_02_anim/color_time")


func _process(delta):
	if color_time:
		pass

func _ready():
	set_process(true)
	mesh = get_node(".")
	color_time = get_node("/root/entity_test/entity_02_anim/color_time")
	self.get_mesh().surface_get_material(0).set_parameter(3, color1)


func _on_color_time_timeout():
	self.get_mesh().surface_get_material(0).set_parameter(3, color2)
