Change color of canvas modular over time

Nerdzmasterz

I have a canvas modular which depicts the sky. I'm trying to make it slowly fade from white to black and back as day turns to night and back. I would offer a code if I had it, but I honestly have no idea on how to go about this. Please help?

Thank you.

The easiest thing to do would be to use the AnimationPlayer and a property track.

Does it work with 2d lighting? Part of the game is keeping a light going- be it from a fire, a flashlight, or whatever.

Yeah, you can animate anything. However, if you want it to change dynamically (like due to game events) you might have to code it with GDScript. Modulate is just a Color, so you can set it like any variable or use a Tween.

That's what I'm after- dynamicly changing it due to the night/day event, which will be called with a timer. Unfortunately, I have no idea how to do that.

This kind of looks like what you are trying to do:

Now I can't stop the animation from looping. Please help?

extends CanvasModulate

var timer

func _init():
	timer = Timer.new()
	add_child(timer)
	timer.autostart = true
	timer.wait_time = 0.5
	timer.connect("timeout", self, "_timeout")


func _timeout():
	get_node("AnimationPlayer").play("Day")


func _on_AnimationPlayer_finished():
	get_node("AnimationPlayer").stop()

There is a setting for looping in the editor. You can set it by code, also.

I think I got it.

Here's the finished code:

var timer

var is_day = false


func _init():
	timer = Timer.new()
	add_child(timer)
	timer.autostart = true
	timer.wait_time = 1.1
	timer.connect("timeout", self, "_timeout")

func _timeout():
	if not is_day == true:
		get_node("AnimationPlayer").play("Day")
		is_day = true
