It is absolutely optional, you can ignore the linter. The linter's job is to help you write idiomatic code. If you don't want to, then don't use a linter or just ignore the rules you don't care to follow. At no point does luacheck change your code, it only informs you of issues it finds.

check the wiki to make sure you're using it correctly

the underscore method is idiomatic Lua so i think it's fine~

LOVR is written in C99 and LOVE is written in C++ so they aren't really compatible, no. On a different note, I've been using LOVR a lot recently with @shakesoda and we're working on an online multiplayer social game with it. We've made a fair bit of progress so far! Without trying to shill my own wa...

I definitely like the _ idiom. If I am calling a function that has optional variables, I want it to be very obvious if I am not using them. A note about your example, in Lua you can just leave out trailing variables if you do not need to use them. function love.keypressed(_, scancode, _) could be wr...

I think in general for Lua the usual choice is LDoc, which is the Lua documentation generator that uses the syntax denoted above. I use it for my libs.

Whoa, this is super cool! I <3 the original Shining Force on Genesis, never played the sequels. Is the art original or did you find it somewhere? Definitely gonna keep an eye on this project.

it seems like your video card driver isn't installed. Go here if your laptop model has the GeForce 9200M graphics chip, or here if it does not. download the nvidia (or intel) driver and install it, then your graphics should be much faster and have more features.

You could just do love.graphics.draw() with the x and y coords as the circle's center coords minus the circle's radius. This is correct but there is a minor detail missing. You want to place your texture at the circle's center and then use half the width and height of the texture as the offset valu...

you are drawing the whole texture, you want to send the quad with your texture.
there is a library called anim8 you might want to look into, it's pretty good at helping with animations
