How to get proficiency in Shuffler
As already seen in the Load and Save features, source files (files that contain all information needed to reproduce a map or Model in Shuffler applications) are identified by smp (Shuffler MaP) extension.
Basically, a smp file is a text file. For this reason, if you explicitly omit the smp extension, the system will consider your saved file a txt file (but you can just rename it from .txt to .smp).
Thus, you can edit the smp file with any simple Text Editor like WordPad or any other software that can edit a text file and then save it without adding any other code.
Inside the smp file you can find few (or many according to complexity of your map) code lines written in XML language.
