Dev Log: Quick Lighting Test

Dev Log: Quick Lighting Test

As a quick experiment I wanted to see how Otter would be equipped to handle a simple lighting set up. The basic set up is just a big render texture that is filled with a dark color with a blend mode set to multiply. Then light is rendered to the render texture with a blend mode of additive. The result is a layer of shadow that can have light rendered to it.


The code for this set up right now is pretty straight forward as well. I'm using a black and white image for the light. Just a black rectangle with a white radial gradient in the center.

Here's some sample code to show how this effect is achieved with Otter!

//set up the surface
public Surface SurfaceLighting = new Surface(Game.Instance.Width, Game.Instance.Height, new Color("379")) {
Blend = BlendMode.Multiply

//set up the light
public Image ImageLight = new Image(Assets.ImageLight1) {
Blend = BlendMode.Add

//add the surface to an entity to render it
//this happens in an object's initialization

//render light to the surface
//this happens in a Render() function
ImageLight.Color = Color.White;
Draw.Graphic(ImageLight, Input.MouseX, Input.MouseY);
ImageLight.Color = Color.Red;
Draw.Graphic(ImageLight, Input.MouseX + 500, Input.MouseY);
ImageLight.Color = Color.Blue;
Draw.Graphic(ImageLight, Input.MouseX - 500, Input.MouseY);

Did you cut parts of the code? Because it seems really odd to me that a function contains public fields.

Yes, hence the comments.

Hi! My name's Kyle, and I make video games most of the time in Denver, Colorado. Here you will find my thoughts, games, websites, doodles, and other stuff like that. I worked on Snapshot, Offspring Fling, and a whole bunch of other games. I also created and maintain Otter, a 2d game making framework. If you want to get a hold of me use the form on the bottom of the page, leave a comment, or just tweet at me. I try to post three times a week. Thanks for stoppin' by! You're the coolest.
