How do I add custom maps?

[Everton747]

I'm going to take part in a commemorative tournament, and it will include some classic maps like Cobblestone and Aztec. I already have the radar images for the maps — is there an easy way to add these maps? How do I calibrate or configure the meta.json5 file?

The best docs are the comments in the meta.json5 files, but in short you need to figure out through trial and error:

• The offset of the map, because the corner of the screen that the radar considers to be 0, 0 is never what the 0, 0 coordinate of the map is. You'll need to fly around and find what values for the offsets work.
• The resolution of the map. All radars are the same square, but maps vary wildly in size. You'll need to figure out what magical value makes the dot on the radar move the same distance on the radar image as a player does in game.

The way I did it was by going into the map and placing bots in different sharp corners of the map. That way you have a bunch of known dots on the radar that you can trial and error the correct values with.

If you figure it out please do open a PR or email it to me so others can use it too!
