Prototype of an edit mesh for my navigation mesh pathfinder

Yesterday I began toying with the Editor API to create a simple edit mesh plugin for my navigation mesh pathfinder.

I've been struggling with mouse event and all, but I managed to build a prototype.

I plan only to implement the following features:

• Moving vertices
• Removing vertices
• Create triangle from 3 vertices
• Create vertex along border edges (outside edges)
• Name link edges (inside edges) to be accessible with code to open/close connection between triangle (for the pathfind algo)
• Remove triangle
• Remove edges

If there is an interest, I'll release the 2 classes some where for others to extends.


Does Unity expose an API to save/export a meshes? For the moment, the plugin seems to affect the original prefab: subsequent GameObject based on the same prefab preserve the deformation till I Reimport my mesh, even though I Losed prefab.

 

Unity doesn't have a native file type, that I'm aware of.

There is the ObjExporter script, but I'd suggest writing a Collada exporter (XML based file)

 

Thanks, I'll go with Collada then !

 

For those looking for a Collada export script, I finaly had some time to finish the exporter.

Support for mesh only (vertices, normals, colors). Yeah I know... no texcoord / materials... I was only looking for raw-mesh
