@MagpieMcGraw I see. Do you have a programming day job or do you only code as a hobby or whatevs? (2 days ago)

@SaltyPepperG yeah I've gotten better at this over the years, but when my final tasks involve "talk to other humans" I shut down hahah (2 days ago)

@TyrusPeace hmmm right yeah that makes sense. I wonder if I tied my chill out things to my projects more if it would help (drawing, etc) (2 days ago)

Also I feel like I'm at the very end of Sky Sisters dev and the rest of it involves doing things I don't like so I'm procrastinating forever (2 days ago)

@MagpieMcGraw right I have heard that actual coding time can be like only 2 to 4 hours a day for most people :o (2 days ago)

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.

Do you want to make a Let's Play of one of my games, or a just a video featuring footage of my games? You have my full permission to do so! Even if you are monetizing your videos, you still have my full permission to use any footage from any of my games. Go for it!
