CaveGen now has an editor for the HATPCR event system - i.e. checkpoints and messages. It's in the Events tab under Editor.

It's not the all-singing, all-dancing visual editor I dreamed of - it's just a textbox for adding the event code. This is better than before, when it was impossible to add events to CaveGen levels.

This is really cool! This will make cavemaking a lot easier.

I would suggest having the editor show the coordinates of a tile when mousing over it, I think CaveMaker does this. It's pretty frustrating to have to count boxes one by one in order to find coordinates for events.

Good suggestion - I'll look into it.

Yeah Cavemaker is row, column, and 0-based. Some people complained but I insisted lol.
I still plan on adding tutorial message support. No plans to support HATPCR.

Background types, terrain types and the basic water types (not the new fancy ones) can now be selected from Properties.

You should probably make it show coordinates column row and one-based to make events easy. The internal coordinates are actually zero-based row column, but I went with a 1-based (x, y) for events to make things more intuitive.

P.S. - This is awesome

Done. There is now a 1-based (x, y) coordinate display in the bottom-right of the editor.
