Is there a list for all modding commands available now? I've got an idea of a new skill set but the modding grammar is really puzzling me and there isn't even a list of commands(or i haven't seen one). So is there anyone exists now or somebody willing to make one?
You can check on the modding wiki, there: http://dredmod.com/wiki/Main_Page And there's the modding guide thread on this forum, as well as the reference thread. Other than that, the best way is to just delve into the code written by other modders.
You have to explain what you mean by commands, there might be a page there but you're not looking for the correct thing.
I reckon that as "function" you mean parameters. They're on the wiki I linked, and also in the reference thread. And if by "function" you mean something akin to what you use in Java, then they're not here. And thanks Cthulhu for that, I'd lose my sanity if I had to deal with Java even in my free time. And if you really have no idea what's going on, just take one of the simpler mods and take a look at it, try to make sense of what is in its code.
