HXSL cheat-sheet

This is a WIP of a cheat-sheet that I will finish Eventually™

Types

Mapping of the shader types to Heaps types:

Float = Float
Int = Int
Bool = Bool

An Unofficial Heaps FAQ

I (Yanrishatum) see too many same questions. They irritate me.

Translation

"How dare you come into this chat and not realize that i am the GOD of heaps and that you MUST check out MY documentation1!!! Im veyr abngrey!!!" - translation from someone in chat.

Very accurate, I highly approve.

FlxSpriteGroup

• FlxSpriteGroup shouldn't exist, but Flixel's "easy to get into" mindset means it has to exist. So now, the class is halfway between AS3 (sprite grouping is the default) and Kha (sprite grouping is DIY)
• Issues: setting alpha to 0 is unrecoverable. MouseChildren handling subpar, especially compared to flash.display.Sprite#mouseChildren
• Potential solution: give FlxBasic/Object/Sprites a parent:FlxTypedGroup<> property and propagate that change throughout the lib
• Impact to lib: major
• Effort required: possibly a lot
• Breaking: mouseChildren behavior could be changed to match AS3's

Inheritance

• Flixel greatly relies on inheritance, which makes it difficult to use

AustinEast

To get Haxeflixel to maintain 1:1 pixel rendering at any scale for desktop targets:

In your Project.xml, add a new window property with an desktop conditional, resizable set to false, and the desired width/height to match the resolution you'd like to maintain.

<window if="desktop" resizable="false" width="320" height="180" />

Apply a shader to the FlxGame instance or the main FlxCamera instance as a filter. The base FlxShader can even just be used if the project doesn't require custom shaders.

FlxG.game.setFilters([new ShaderFilter(new FlxShader())]);

Conventions

• A = [xA, yA] is a point on the 2D plane. Same for B, C, ...
• lengths are in any unit (ex: pixels)
• code snippets are in JavaScript

Degrees to radians

angleRad = angleDeg * Math.PI / 180;
