People will say setplayerdata commands don't work. THEY DO. You people just do it wrong. Ok here's my explanation.
Commands:
-setplayerdata prestige <value>
-setplayerdata experience <value>
-setplayerdata kills <value>
etc.
How to make it stick:
-Delete stat files IN GAME or else you just did that for nothing, your stats will just reset
-Join a game
-New stat files created
There. You said it didn't work but stat files overwrite your rank every restart. This is for people that probably didn't know it and also people that don't like trainers, I still recommend just using one but it's your preference. Have fun leveling
