Working on an RPG: Generating the Map

I’m now over a month into the basic RPG I mentioned in the last post, so a bunch of systems are in place. In my last post I talked a lot about the narrative system Ink, but this time I want to get back to what is a frequent topic on my devlog: procedural generation of maps. Here is what I came up with for the map of city regions:

rpg-regions-map

(The weird batches of horizontal lines are actually lines of text. That’s just to test applying textures to quads strewn about the map, and will eventually be replaced with images of buildings and trees.)

Outline Both Squares and Hexes

So I’ve been experimenting a lot lately with rendering lines on the ground, for the map in strategy and tactics games. Last post I already had this effect working for a square grid, but it wouldn’t work for hex grids because it was dependent on drawing pixels to match the grid. I ended that post by brainstorming ways to support hex grids, and have had great success working on the problem since then.

I uploaded a WebGL demo to try, and here’s a video showing the territory outlines shader working on both square and hex grids:

Shader that renders Border Outlines

Merry Almost-Christmas! I normally do a blog post every month on the 25th, but I wanted to do this one a few days before then because of the holidays.

Last month I had described my plan to render border lines on the ground (think territory in a strategy game, or movement ranges for tactics games). Here’s an image showing the result of my experimentation:

Hey, looks pretty good if I do say so myself! That’s a smoothly glowing outline drawn on the ground, surrounding a discrete region of a square grid, with the outline nicely rounded at the corners.

Border Lines on a Strategy Map

Happy Thanksgiving!

A couple months ago I was noodling on techniques for displaying the map in a strategy or tactics game. Well, lately I’ve been thinking a lot about one specific aspect of how those maps work: representing borders on the map.

I’m talking about the colored lines on the ground in this screenshot:

Terrain from a Convex Hull and Triplanar Mapping

As I pointed out last month, I’m putting my personal projects on a hiatus for a while. Instead, I’m going to talk a bit about interesting game dev and graphics stuff that’s come up at work. Naturally I can’t blab too many details about our internal projects at PEAK6, but I do want to point out some of the publicly available technologies and/or resources.

The project I’m currently working on has involved a witch’s brew of proc gen techniques. I want to focus on two in particular: convex hulls, and triplanar mapping.
