Hey. So i decided to try to make a platformer, and after thinking about it for a while i realized that i'll run into a few problems while making this..Here's the first one: Levels.

The problem is, I have no idea how to go about making the levels. I mean i have some ideas, but none of them are good. I did have one idea which i think could work, But i'm not sure how to execute it. I'd need some way of saving/loading tables to/from files.

I included what i have so far below , But there's basically nothing there yet..just a function that adds a platform at a random position (just a test)

EDIT: I came up with a way to do this that works pretty well. But i'm still open to suggestions..there could be a better way than mine. haha.

You need to start digging this forum. Almost everything is already answered around.
Here is a very recent topic that could help.
viewtopic.php?f=4&t=7884. If you follow my response on that thread you get a way of loading/saving maps (tables).

Also you don't seem to have something to even think load/save anything. Work first in do some jumping/plataform engine.

EDITED If you don't present your ideas even that bad, lovers can't help you much...

Saving tables to strings (commonly known as serialization) is actually kind of easy in Lua:

Code: Select all

function serialize(val, name, skipnewlines, depth)
	depth = depth or 0

	local tmp = string.rep(" ", depth)

	if name then tmp = tmp .. name .. " = " end

	if type(val) == "table" then
		tmp = tmp .. "{" .. (not skipnewlines and "\n" or "")

		for k, v in pairs(val) do
			tmp =  tmp .. serialize(v, k, skipnewlines, depth + 1) .. "," .. (not skipnewlines and "\n" or "")
		end

		tmp = tmp .. string.rep(" ", depth) .. "}"
	elseif type(val) == "number" then
		tmp = tmp .. tostring(val)
	elseif type(val) == "string" then
		tmp = tmp .. string.format("%q", val)
	elseif type(val) == "boolean" then
		tmp = tmp .. tostring(val)
	elseif type(val) == "function" then
		tmp = tmp .. "loadstring(" .. serialize(string.dump(val)) .. ")"
	else
		tmp = tmp .. "\"[inserializeable datatype:" .. type(val) .. "]\""
	end

	return tmp
end

This function creates legal Lua code that you can run at any time using loadstring().
