Documentation on the RPG Maker Xp map format?

[pokemonmasteraaron]

Does anybody know where I can find information on the rmxp map file format for editting in a hex editor?
I was curious, because I am blind and cannot map using the graphical map interface but if I could perhaps create an editor or simply make the maps in binary. So, does anybody know if such documentation exists?

Well, for starters you can load maps using:

map = load_data(filename)

If I do remember correctly the map's tile data is stored in the Table: data

map.data[x position, y position, layer 0 being the lowest and 2 being the highest] = tile id

You could then save the data like this:

save_data(filename, map)

so a complete code would be like this:

filename = "Data/Map001.rxdata"
map = load_data(filename)
map.data[0,1,2] = 384
save_data(filename, map)

Anyways, this is the easiest way you could possibly edit your map's data without the editor.

This isn't quite what I am looking for.
I need information on the rxdata map format so that I could modify it or create it from scratch.

rxdata is stored in Ruby's Marshal format. Unfortunately, you need to know what all the class/module definitions are before you can open it.
I've found this google code project that opens most of the files, but is missing some info for map data specifically :( I'll post here again if I can get it working.

Thanks a ton! This should help! Thankyou!

Hey there, I did make some progress with this; I was looking into converting the data for Pokengine before I left that project.

I have a thread here: https://pokengine.org/phorums/?viewthread=1741 that might be useful to you - one of the components of my importer is a Ruby script that converts the Marshal data to the more readable YAML. The rest is python scripting to convert the maps to Pokengine format.

Good luck!
