Create custom levels
 
 

Using the console for custom maps

Your custom map should be placed into the /maps/ folder.
 
 
Open the console using tilde (‘~’), and use the map command to load it.
 
 

map <mapname>

 
 
If there is no corresponding save file in the /sav/ folder, it will create a new instance of the level. Once you quit the game or change level, it will save a copy here.
 
 
You can load in new changes of the source .map file by deleting the save file.
 
 
 

.map format

You can find examples of .map files in the maps/ folder of the source code.
 
A good one to reference is principle 4 – [harrygodden.com] .
 
 

Overview

 
.map files are entirely text based, meaning you can edit them in notepad or whatever other text editor you would like.
 
 

cat maps/cmp_t04.map
#############;
###-#####-###;a:aa,b:bb
## ##;
## ##;
## ##;
## ##;
## ##;
## ##;
######+######;ab:abab
#############;

 
 
NOTE: map files are stored upside down!
 
 

Symbols

 

• ‘ ‘ Spaces denote a cell which you can place pieces into
• ‘#’ Pounds represent ‘wall’ tiles.
• ‘+’ Pluses represent input cells
• ‘-‘ Minuses represent output cells
• ‘;’ Semi-colons represent end of line

 

Attributes

 
Each input or output you define requires attributes to be written after the end of line marker.
 
 
Attributes are a string of letters, each ‘terminal’ seperated by a comma, and each ‘run’ of marbles is seperated by a colon. These create runs, and expected output runs of marbles where each letter (a-z or ‘ ‘) is a different colour marble.
