Well, considering that you have to jump through hoops to work with objects in Lua, it's pretty easy to avoid singletons :P There isn't really a wide or narrow definition of singletons - it's pretty straightforward, as far as design patterns go: https://en.wikipedia.org/wiki/Singleton_pattern . It's ...

Interesting. I'll try to dig up the other thread Zorg is telling us about.

Well, this is really interesting. I didn't stumble upon that wiki page until now. I have one question tho: what's the purpose of the sleep() call at the end of the while loop? if love.timer then love.timer.sleep(0.001) end Doesn't this pretty much hardcode a thousandth of a second's worth of lag in ...

I have no idea how to use this for an actual game mechanic that will not feel gimmicky (I will however take the challenge of coming up with something) and I don't have anything meaningful to contribute to the discussion. But I just wanted to say that this looks awesome Well done.

Of course, it depends on what he wants to achieve. But there's quite a bit of seemingly simple functionality that you need transformation matrices for. For example, registering clicks on stuff that moves around (or any other thing that needs pixel checking). Also, drawing is easy when you already kn...

This is usually achieved using translation matrices. There's a bit of work to do to implement it on your own, but it's a basic requisite for 2d video games so there are quite a few tutorials out there explaining how to achieve it. https://en.wikipedia.org/wiki/Translation_%28geometry%29 As far as I ...

What did you try to do and what problems did you run into when doing it?
It's easy in principle, just change the camera's position to the player's position in each love.update() call.

When I'm trying to decide on using a library for an application, I usually ask myself these questions: - what do I need my application to do - what does the library provide - how big is the overlap between the two And then there's some other stuff you need to take into account, like compatibility wi...

A separate forum for tools and libraries would be great, as it's currently a bit time consuming to sort through everything trying to find a library. It would also be useful to have a centralized list of the most useful user-written tools - either a wiki page or stickied topic (with no useless blabbe...
