Hey, does any one know of a mod that makes it so you save variables in game? I'm trying to make an RPG and it would help a lot for making check points

You mean save the events? If not, then no; there is no such mod.

Blockland forums, search Variables, botom of the topic, a "Saving variables" what do you know? Saving / loading variables, andways how to use it:

Saving:
On activate > Client > Save Variables > [variable 1]
On activate > Client > Center print > [Saved!]

Loading:
On activate > Client > load Variables > [variable 1]
On activate > Client > Center print > [Loaded!]

Also, im working on a RPG too! it's called Blue frog RPG, i need a anti-save script though.

Thanks! I'll try to find the server, and if I find an anti-save script I will tell you.
