Forward Progress

It's been a busy few weeks since I updated this blog, but I've been hard at work adding several new features to the engine. These new features have included basic collision detection, a sound system, and simple projective shadows. Right now, I'm in the middle of upgrading the lighting system to accomodate spotlights and multiple light sources (as opposed to one). This is taking longer than I expected, but theoretically it should be done by the end of the year.

In a previous post, I said I would talk more about one of the features I added earlier this year: the contour map tool. This tool (seen below) has two main capabilities. One feature is the ability to create contour maps from scratch, and then, using Bezier curves, allow the user to manipulate a series of concentric rings in order to create mountains, hills, lakes, valleys, or even simple riverbeds.

Eact tiny white ring in the picture above is a "handle" which the user can use to shape the blue contour lines. I can imagine this would get tedious if you wanted to create a multitude of unique mountains or lakes, for example, so in the future I might allow for some procedural mountains to be rendered by this particular tool.

The other feature is the ability to take a pre-existing contour map which has been pre-color-coded and then convert that into a 3-D heightmap (using the "Import File" option above). I haven't fully tested this particular capability of the tool yet, but I plan to in the near future with an area lake map. The goal, of course, is to create more realistic terrain features and hopefully begin to use various real-world features in the first game I hope to release using this particular engine.

Mt. Ararat, anyone? ;-)
