Re: How can I make a Map Editor?

To convert from screen x/y to map x/y coordinates, you need to divide the screen coordinates by your gridSize. For example, if your grid size is 64 pixels, then ...

Re: "Questions that don't deserve their own thread" thread

Just a little question, say there are these lua files, file1, file2 and file3, file2 has require "file1" so file2 can use the functions, variables etc. in file1 then file3 has require "file2", so file3 can also access file1?(as file2 has require "file1") or am I wrong?

Is this a good timer that I made?

So I tried to make a simple timer function, so here's what I made: activeTimers = {} function checkNumber(n) if type(n) ~= "number" or n < 0 then error("[Timer]The delay argument must have a positive number.") end end function timer(delay, func, ...) checkNumber(delay) table.insert(activeTimers,{del...

and is there a difference between metatable and an ordinary table ? :?
