I will touch on a few key concepts but I recommend afterwards using a guide like The Book Of Shaders to understand fragment shaders in more detail. text/html 2025-09-30T17:26:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.orx-project.org/wiki/en/tutorials/shaders/glow?rev=1759253179&do=diff Glowing Ball of Light Summary In this tutorial, we're going to create a glowing ball of light, that looks something like this: Naive Attempt Let's go ahead and use this image in a scene with alpha blending: [GlowingBall] Graphic = @ Texture = enobayram_glow_normal.png Pivot = center Position = (0,0,0) text/html 2025-09-30T17:26:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.orx-project.org/wiki/en/tutorials/shaders/hexagongrid?rev=1759253179&do=diff Hexagon Grid Tutorial Introduction This tutorial demonstrates how to generate hex grid using shaders and how to track hexagon tiles based on the screen coordinate (mouse cursor tracking).

It is based off of the this Hexagon Grid Tutorial, the key difference being that this example makes use of an axial/cubial coordinate system for pixel-to-hex calculations, as opposed to the grid-based system used by the old tutorial. text/html 2025-09-30T17:26:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.orx-project.org/wiki/en/tutorials/shaders/lighting?rev=1759253179&do=diff Lighting tutorial Summary This is tutorial shows how to use shaders for lighting with auto-generated normal maps. NB: If you want to see how to use orx while using C++ for your game, please refer to the localization tutorial. As we are NOT using the default executable anymore for this tutorial, the tutorial code will be directly built into the executable and not into an external library. text/html 2025-09-30T17:26:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.orx-project.org/wiki/en/tutorials/shaders/maps_in_a_shader?rev=1759253179&do=diff Maps in a Shader TiledToOrx, OrxImageMap and Tilemaps in a shader, what's it all about? Long scrolling levels can be constructed using graphic tiles laid out in a large map. Normally, you would use a paint routine to read all your tilemap information from a data configuration file, and render them as objects to your scene. text/html 2025-09-30T17:26:19+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.orx-project.org/wiki/en/tutorials/shaders/shadercoordinates?rev=1759253179&do=diff Shader Coordinates Tutorial Summary This tutorial shows how to connect shader based coordinates with the screen coordinate system. This project is intentionally made simple to allow for better focus on what it takes to work with just shaders.
