I want HP increased by using the buy menu. But does not work! Well, yes, but it is only for recovery of blood <100 to 100, I want it to increase HP. What about the other code?
Some mods allows you to have more than 250 HP, Zombie Plague (if I'm not wrong, at least I mean some zombie gamemode) or my File does not exist (11133).
Take a look at setmaxhealth - the regular health system is limited to max health of 250 though. So workarounds are required if you want to have even more health.
