white out

[drarem]

What's an easy way to get the entire screen to fade to white or fade to black?

 

Thanks.

Yeah, combine that with alpha blending. See the other context commands.

simple example of fading to black and to white:

window = Window:Create("fade example",0,0,800,600, Window.Center)
context = Context:Create(window)
world = World:Create()
camera = Camera:Create()
camera:Move(0,0,-3)
light = DirectionalLight:Create()
light:SetRotation(35,35,0)
model = Model:Box()
model:SetColor(0,0,1)

alpha = 0.01
toggle = 0.005
color = 1

while window:KeyDown(Key.Escape)==false do

	if window:Closed() then break end
	
	model:Turn(0,Time:GetSpeed(),0)

	if alpha>=1.0 then toggle = -0.005 end
	if alpha<=0.0 then
		toggle = 0.005
		color = 1 - color
	end
	alpha = alpha + toggle

	Time:Update()
	world:Update()
	world:Render()

	context:SetBlendMode(Blend.Alpha)
	context:SetColor(color,color,color,alpha)
	context:DrawRect(0,0,800,600)
	context:SetColor(1,0,0,1)
	context:DrawText(string.format("alpha: %.2f",alpha),0,2)
	context:DrawText("color: "..color..", "..color..", "..color,0,22)
	context:SetBlendMode(Blend.Solid)
	context:Sync(true)
end

Bits of code like that should be kept somewhere, maybe a code snipets section. Very usefull.

Anyone know where can I find this link now? I was looking for a fade-to-black example.

Thanks

That link is just the contect:DrawRect() from the old command index. If you look 5 posts up, I have code that shows how to fade from black to white and back to black - just modify it for your needs:

Ok cool thanks,

I'm just trying to wrap my head around the purpose of DrawRect()  in your sample.

All I am doing is drawing a rectangle the same size as the window/context and fading to black/white by just adjusting the alpha component in the rectangle's color settings.

Interesting,

So if I were to hide the original camera with this script running and show another camera, should the alpha level would persist in the new camera?
