I've been making my Löve games on my own 64bit Vista computer, and when I play my games on other computers (A 32bit Vista, and the old XP school computers) they all run the game faster. There is a literal increase from steady 60 FPS on my PC to between 200-400 FPS on the other computers (Tested wit...

Translating key codes into characters directly is a bad idea because it doesn't take the user's keyboard layout into account; international users are out of luck, for example. SDL actually provides automatic translation of key hits into Unicode characters , but I guess Löve doesn't expose that funct...

Please add network support :) I'd like to do it, but synchronizing physics seems a bit hard to me ... It should be doable if you keep a fixed logic timestep (say e.g. 30fps); then the only thing you need to send across the network are the other player's inputs. This way each instance of the game sh...

Stencil buffers could also be used for that: every render operation would write into a stencil buffer, and new fragments only get rendered where the stencil buffer has not been set yet.

Floating point multiplications are dirt cheap on modern CPUs though; even a Lua function call has more overhead probably. So performance would hardly be an issue. One would just have to go through all relevant API functions and apply this scaling everywhere, which would be a slight annoyance, I assu...

I haven't used Love.physics yet, so excuse if this doesn't make sense, but would it be possible for the physics interface to simply scale all pixel units it is passed by a certain amount? That scaling factor could also be set by the user, if he needs to.

You know, you don't have to use Box2D. Many of the retro platformers out there would feel wrong with sophisticated physics like that, and actually are very fun the way they are, with only basic physics.

For the trigonometric functions, maybe something like this will help you: http://www.clarku.edu/~djoyce/trig/

For your "point in triangle" problem, there are some simple algorithms; see e.g. here: http://www.blackpawn.com/texts/pointinpoly/default.html However, since you only want to generate points within the triangle anyway, you can do the following: set h := height of your triangle for each poi...

The vsync issue is something we can't really fix because it seems to be a driver issue. If the driver decides to do a busy spin while waiting for the vsync, then I guess we're out of luck. That said, yes, a manual solution using sleep() is the next best thing, even though it isn't real vsync and thu...
