The thing is, os.execute is like the keys to the kingdom, and when you hand someone those, you can't really say "only come in Mondays and Tuesdays, and don't steal anything while you're in". In this specific case, one thing I could do is: renameFile('oldfile', 'newfile"; format "...

In that case, can you explain so I don't make this mistake again?

You can use os.execute() but it's a little crude and obviously platform dependent. Here's a quick example. Only tested on Windows and doesn't return any meaningful errors. -- Renames a save directory folder/file. function renameFile( old, new ) local dir = love.filesystem.getSaveDirectory() local co...

tile = setmetatable({}, tile_type.stone_floor) Does it mean that if I will look for tile.color it will check the empty {} and then it will look in tile_type.stone_floor? You're only setting the metatable with that line. The magic happens with the metatable's __index. When you try and get a value do...

LOVE is perfectly capable of handling roguelikes. In fact there are a few examples in the projects forums. The freezing at the start is likely because the window is being resized right after it was created using love.window.setMode(). You can avoid this by using a [wiki]conf.lua[/wiki] file. Also yo...

This problem is called called texture bleeding. It can happen even without using sprite batches. The most common way around this is to pad each tile with a 1px wide border with the same color as the neighboring pixel. You can also render the viewing area to a texture and scale that instead but it ha...

I just really hate the idea of copying someone elses work like that. If you want to create your own OOP implementation for learning or control over your projects that is one thing but I hope you reconsider this. If you program in any capacity please understand you will be using something someone el...

Now we're getting somewhere. uh... k... I don't see what setting a index equal to the table of which the index is in does, Let's take a step back here. You probably understand now that __index will be checked if the values aren't found in the original table. You shouldn't have any problems understan...

You're making this harder than it actually is. OOP is really just about extending a set of functions and data. I mean, this is essentially OOP in Lua: -- OOP Library. Open source license. Send donations to Kadoba. Do not steal. function inherit( parent, child ) child = child or {} for k,v in pairs( ...

You can think of the TMX file as a project file, and the exported JSON/Lua as a program-ready file. I'm not sure if Kadoba was aware that Tiled exported directly to Lua since ATL made use of XML parsing, but STI uses the native Lua spec so hopefully it will load files faster and allow more flexibil...
