@codeapparat Hmm okay, there's BufferData, but now how to convert any of that to color data o __ o (Today)

@codeapparat Hmm right but how do I get such an array from SharpFont's bitmaps? (Today)

So I'm using System.Drawing.Bitmap as part of the process to Texture2D here, but I'm thinking this might not be the best idea... (Today)

Yeeehaw loadin' a whole font into FNA with SharpFont t.co/TJfjxY1MPs (Today)

@AsherVo making video games is like 10% game stuff and 173% UI design and programming (Today)

RT @tripleboop: 3v3 tourney for #towerfall at 3B: t.co/KevlbepVWw cc @kylepulver @MattThorson etc rt rt rt (Today)

@ChevyRay @eigenbom I have a W showing up for now #blessed t.co/0RzVOwdYCn (Today)

@ChevyRay @eigenbom Ohh I was looking at the font code you gave me for SDL2 as a reference... but maybe we shall chat again soooon <3 (Today)

@eigenbom eh maybe if I was doing 3d, I've given it a few shots and I just don't like the feel of the workflow for 2d :I (Today)

@eigenbom Sort of. A lot of my utility/helper stuff is instant portable. Rebuilding the rendering stuff though using old code as a guide. (Today)

@eigenbom UHHhhh trying to figure out if FNA is gonna be usable for my next project. Right now I am in font/text rendering hell. ;D (Today)

Okay lets try to take this SharpFont library and uhh somehow... render text with XNA... and uh... *barf* (Yesterday)

@jacobalbano I compiled my .fx file into a .fxb with that fxc.exe program from the direct x SDK. Can be just used on its own. (Yesterday)

this may just look like a pink silhouetted graphic but it represents a shader actually working with FNA yeehaaawww t.co/AbriJFfgA5 (Yesterday)

@flibitijibibo Probably best thing is on google chats pulverk@gmail.com (Yesterday)

@flibitijibibo @larsiusprime Nope I have no XNA projects at all, starting from scratch. Will check out this fxc.exe thingy (Yesterday)

Dear FNA people, what is the process of getting a shader compiled and loaded? (Trying to avoid content pipeline stuff, using just files.) (Yesterday)

@flibitijibibo YUP Going to give it a whirl today! :O (Yesterday)

POOP I totally forgot to put FNA in the poll (Yesterday)

@StegerGames UGGH yeah the music stuff (and shader stuff) is what is making me feel weird about using XNA. (Yesterday)

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.

Image

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
AddGraphicGUI(SurfaceLighting);

//render light to the surface
//this happens in a Render() function
Draw.SetTarget(SurfaceLighting);
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);
Draw.ResetTarget();

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!
