It's interesting to read people claim that hotswapping is impossible when I've been doing it since forever~ I understand the point, that doing it for arbitrary lua code is impossible, but when you're the master of your own app you can apply the structure you need to make it work yourself. example he...

I actually go one step further, I don't even keep sprites in objects: instead I have a sprite/animation manager that I pull from, and that has its own internal state to do, for example, switching between frames over time. then my draw methods look something like function player:draw() assert(Animati...

depending on how much you control the OS you can use something like xvfb to make a "virtual" window. That said, with your example maybe software rendering could also work? Instead of using a canvas just edit your ImageData directly like so for iy = y, y + w - 1 do for ix = x, x + h - 1 do ...

here is the specific adb command I've used in the past
this isn't nearly as instant as I liked but it worked

Does anyone know how to capture the button press against the 'X' (i.e. to close the window)? I've been looking into the docs and see that p_open is the second parameter in imgui.Begin() but it when i click it in my code it doesn't seem to have any effect/change the boolean value. This is in the one...

This is called line-of-sight, or sometimes field-of-view.
Here's an article describing a few possible approaches, although it isn't the only approach out there:

In a way this feels like giving a new driver the keys to an ultrafancy sports car, but the exact thing you are looking for is coroutines. http://lua.space/gamedev/using-lua-coroutines-to-create-rpg and here is an online discussion asking whether or not this is a "good" idea, and the subtle...

approach 1: implement swept collisions, or steal a collision engine that does it for you approach 2: just increase the tickrate until it stops being a problem :p approach 1.5: instead of increasing the tickrate of the entire game, do "subticks" where you lerp between the old tick and the n...

I don't have a real complaint, but more of a difference of opinion I guess While I def value computer literacy, I think (for me at least) the single least interesting thing about programming is the part where you wrestle with your OS or tools to get them to do the thing you want them to. Starting ou...

If you have a server you'd like to proxy through, then you don't need NAT punching because you can use the server rather than connecting to each peer directly so instead of the data going peer <--> peer you do peer <--> server <--> peer on the server side this just means when you recieve a message a...
