A Lua library by dungeon. You will be able to create isometric games with this engine.

Release notes:

After many months of work, I have the honour to present the first version of the Isometric Engine accompanied by his inseparable Isometric Collision Creator!

The Isometric Engine is a library in Lua which manages Isometrique collisions or “normal” 4 lines! More taken headache.

This library has been designed for the basic types of games RPGs with a main character who move. (but free to you to use it as you see fit)

Everything is under GPL so you can change this library as you see fit, but under some conditions (for details see LICENCE.txt)
