In this example we will show how to add a text and a button to CEGUI::FrameWindow.

RAGE was such a disappointment
A good while ago, I purchased RAGE on Steam. As usual, it was a good deal then. I’m a sucker for post-apocalyptic games like Fallout 3, New Vegas, STALKER-series and the Metro-series.
How to even out light/dark edges of images with GIMP
I was making a huge seamless texture of a concrete wall, when I found out that the original textures were taken with a light source more powerful at the right side. This resulted in images where the left side was darker than the right one.
CEGUI tutorial: Cyrillic Russian fonts
We were planning on going to Steam Greenlight with our game “Burnt Islands” and decided to have more than just “English” language in the game. As we’ve built our own engine it was not so difficult to implement several languages. The solution (and the problem) was CEGUI. It has support for different languages and UTF fonts, but to figure out how to make it work was not so easy.
Debug triangles in Bullet Physics
In our game “Burnt Islands” that is a heavy physics based game in a dynamic world we needed to make physics shapes of the objects in the scene. We use Irrlicht graphics engine in the game with “Bullet physics” as a physics engine. In a previous post “From Irrlicht mesh to Bullet Physics mesh” we described how to make a physics mesh from a graphics mesh.
From Irrlicht mesh to Bullet Physics mesh
There is typically no physics functionality in graphics engines like Irrlicht. If you are using graphics and physics engines instead of one like Unity or Unreal Engine then you will run into a problem called “Irrlicht physics”. Recall that Irrlicht is just a graphics engine. It renders object on the screen and that is all. In order for an object to be able to have physics properties you would need to integrate physics and graphics engines.
Mechanics behind a game engine
We’ve worked on our own game engine (“Monster game engine”) for almost three years. It is this engine we were using to make “Burnt Islands“.
How to turn a photo into a seamlessly tiled texture
In this short post I will show you how to easily turn a photo into a seamlessly tiled texture with just three clicks. I will be using GIMP that is a free and open source software for image editing.
Irrlicht culling problem
We’ve recently had major performance issues while testing the game. Debug information has shown that it was the graphics that was taking from 60 and up to 300 milliseconds per second to redraw all nodes. One of the issues that was discovered in analysis is that terrain ISceneNode had automatic culling EAC_OFF:
GLSL shaders: black dots
Recall our previous post about stretched terrain bug in the game. Shader that fixed the problem gave although an unpleasant bug in the form of many black dots with newer graphic drivers. The black dots are usually a result of a NAN error (not a number) and normally related to bad geometry, a bad shader, light or camera.
