Compiles RED lang into Minecraft schematics
npm install redc
$ npm install -g redc
$ redc -f
All options:
| option | short | description |
|--------|-------|-------------|
| --file | -f | Path to input RED file [required]
| --out | -o | Directory to output .mcfunction (defaults to the current directory)
| --name | -n | Name of the outputted .mcfunction file (defaults to name of <file>)
In node
javascript
import redc from 'redc';
// or: import { compile } from 'redc';redc.compile(...).then(console.log);
// => "setblock..."
`Executing code on the computer
1. Build the code:
2. Find the save file of your copy of the computer (typically in on Windows)
3. Copy the .mcfunction file into datapacks/red/data/red/functions
4. Enter the world in Minecraft (if you are already in it, leave so the game reparses functions)
5. Enter command
6. Go to the front of the ROM and disable the breaker right outside it (the row of pistons)REDlang
REDlang is very low level. Every line translates 1:1 with machine code.
A VSCode extension for syntax highlighting is available for install redlangExample:
use i = ram:0
use counter = device:0@entry
[Main]
i = 0
goto Loop
[Loop]
counter = i
i = i plus 1
i will roll over eventually and then the
will not pass
goto Loop if ifall through
exit
`The code will run like a
loop, writing the index to the first word of device memory, starting from 0 and counting until it overflows at 63.#### Breakdown
- The code defines two variables, allocating their sources and address in memory, syntax being:
use .
- It defines two routines, Main and Loop, tagging Main as the entry routine.
- i is initialized to 0 because there might be some memory from an old execution.
- counter cannot be assigned to counter + 1 because counter` is write-only memory.
