Stewsters-Util

This is a collection of some code that I have pulled out of projects. It is mostly useful for roguelikes.

Old versions located here:

I have tried to port any 2d algorithms I have found into 3d as well.

• Reusable predicate/brush components for map generation algorithms. (http://www.roguebasin.com/index.php?title=Designing_Flexible,_Reusable_Algorithms)
• Kevin Glass's A* pathfinding for 2d grids which I have extended to 3d.
• A KdTree for spatial hashing.
• A scheduler for turns.
• OpenSimplex Noise Functions for 2d, 3d, and 4d noise.
• Djikstra searching for objectives.
• Djikstra map to quickly allow many entities to path to one objective.
• A few Math functions that I have found useful.
• A variant of SquidLib's shadowcasting that reuses the same array.

My apologies for the lack of documentation. For examples on how to use these, look at the tests folder.

How to use with Gradle

Add Jitpack to your repositories:

repositories {
    maven { url 'https://jitpack.io' }
}

Then add it to your dependencies:

dependencies{
    compile 'com.stewsters.util:stewsters-util:0.19'
}

How to compile a JAR

To compile from source you will need Java 8 and to install groovy and gradle. I recommend using https://sdkman.io/ for that.

If you want to jar it up for a use in a project, try this:

gradle jar

How to use as a git submodule

This is really only a good idea if you intend on editing this library within another program.

git submodule add [email protected]:stewsters/stewsters-util.git stewsters-util
git submodule init
git submodule update

Then set up your build system to deal with a subproject:
