E2D is a tool for editing and generating 2D terrain inside Unity. The terrain is created by clicking the shape with mouse, by using brushes or by using the generator. I created it as part of my thesis, so it's FREE. I was also forced to create a user manual Download v1.0.0: e2d demos e2d only user guide doxygen reference manual thesis Features: terrain creation node by node using your mouse brushes to move many nodes at once and apply textures waving grass possible to create caves shape generator texture and grass generator (very basic, though ) plastic surface of the terrain (works nice with lights) Examples: 2D platformer demo with the "lerpz" character from "2D Platformer Tutorial". It's using dynamic lights. Play. Car on a bumpy terrain with quite large terrain (1500m). Play. I probably won't have time to work on this more in the near future, but would like to continue improving this as I'll use it myself. If anyone wants to do any changes feel free to do so However, I'd like to know, so that I could update the tool as well. Here's what's missing: mobile support: I got some troubles with the shaders... will have to figure out how to make them work for mobiles or how to simplify them. terrain splitting: right now the terrain surface must be continuous, but I want to make floating islands of dirt. objects painting: it would be great to "paint" predefined objects like stones or trees and they would attach to the terrain and stay even if the surface is changed. more filling textures: right now there is only one. More textures would randomly (noise) blend together. Well, let me know what you think and if you would like some particular thing added to the tool.
