Inventory help in an RPG game

[Pigeon]

I feel as though your judging me.

Of course, who doesn't judge others?

:/ as in, in a bad way.

You do keep saying sorry, as if you have done something bad. Maybe it's all in your head.

So I read through the Programming in Lua (the tables bit) and watch SockMunkee's tutorials. I have attempted at making an Inventory and it kinda failed. I've done all you asked. Any help now please? And now my feelings of reality are slipping, cheers Azhukar

Cheers,

Any help now please?

You were already given an example inventory code.

And now my feelings of reality are slipping, cheers Azhukar

One step further out of your bubble.

Fine, sure. Thanks. I guess.

Code: Select all

function time:wasted(?)
    if time == "wasted" then
    	log_off_lua = true
    	curse_timewasters_name = true
    	pissed = true
    end
end

    	curse_timewasters_name = true
    	pissed = true
    end
end

Syntax error: ?:1: <name> or '...' expected near '?'

The question mark was for show, not for real code.

Code: Select all

function time:wastedevenmore()
	if time == "wastedevenmore" then
		thoughts = "f*ck off, all I asked for was a bit of help"
	end
end

Is there something you do not understand about the inventory code? Like say, tables? D:

almost everything in the code... + sorry for being rude
