An MCEdit filter to convert a command block chain into a function.
Select a 1x1x1 cube around a non-conditional repeating command block and run the filter. It'll traverse the line and create a function that you can then save.
The filter also includes a small fix for any conditional commands you may have, which is done using an area effect cloud. This requires a dummy objective named SuccessCount in the world.
- MrGarretto for the code to traverse the command block line.
