What is ✦PathPlus✦?

✦PathPlus✦ is a FOSS tool for GameMaker 2014.14 that enhances and expands the regular path assets to include Catmull-Rom and Bezier interpolations. It also comes with useful utilities like simplify, noise, and other ways to manipulate your paths.

PathPlus is released under the MIT license, so you can use it for free, forever.

Current features include:

✦ Transform a linear path into a Catmull-Rom curve (smoothly passes through all control points)

✦ Transform a linear path into a Bezier curve (higer control with curve handles, can combine sharp and smooth corners)

✦ Add extra variables to a point

✦ Bake the resulting curve into a path asset or export it as a .yy to use in your projects

✦ Create a Follower to use your PathPlus directly.

✦ Create a Spriter to draw a sprite along a path. Includes thickness variation and color variation.

Implemented examples include:

✦ A lasso tool that allows you to select instances or arrays of coordinates.

✦ A recorder that creates a path from your mouse movement, storing the relative speeds.

✦ A (rough) path editor.

Please note these implementations are made as an example and are not fully tested or intended to be used as-is!

Other possibilities include:

• Alter path-finding curves to be more varied or smooth.

PathPlus is a library made for the Cookbook Jam 2.

Compatibility: tested with GameMaker 2014.14.
