Ok, good luck. If you plan on having any screen transition effects then you don't need to make a full state just for them, you can do them from within a preexisting state and undo in the next. For example, say you want this: user hits PLAY on the menu, screen fades to black, then fades in into level...

How much have you read on software programming patterns? Specifically the state pattern, it's very cool: https://gameprogrammingpatterns.com/state.html As I understand it, you're encapsulating logic into separate objects, and at one given moment only one of those objects is controlling the game (bot...

Will you design the tilemaps manually, with a tile editor? If so then I'd implement a 'tag' attribute so that you can tag tiles that belong to the same room when you're drawing them (ie set tag to "Room 1", start plotting tiles). This way no preprocessing is needed. If the tilemaps are bei...

It's not even listening. I doubt it consumes CPU. Looking into the source to luasocket, it does seem to be simpler than I was thinking: - https://github.com/diegonehab/luasocket/blob/master/src/wsocket.c#L154 (bind from WinSocket2 on Windows) - https://github.com/diegonehab/luasocket/blob/master/sr...

My only concern is which method uses less (CPU) resources. I don't know if using a listening socket to behave like a global mutex in this way involves any redundant polling from the OS or not.

After some more research, instead of using shared memory objects like I suggested before, there's a safer solution based on this library: https://github.com/oblique/named-lock/tree/master/src It uses a named mutex on Windows (so your program can lock that mutex, which is a memory object, and if any ...

What the Qt libraries use for this is a 'shared memory object', something used with IPC ("interprocess communication"). It's a named block of memory that different processes can access and read/write to like a file that exists in system memory. It's got a unique name, that's how different ...

You could port some Verlet engine into Lua, the rope would consist of several linked segments (like 100 total), each with a distance constraint. There are tons of live Verlet physics demos online using HTML5: - https://subprotocol.com/system/tree.html - https://codepen.io/guerrillacontra/pen/XPZeww ...

Maybe a browser-based tool: http://tmtg.nl/tinyspriteeditor/

Google also suggested PiskelApp, but its website was offline when I tried to visit it: viewtopic.php?t=83198

Code: Select all

if (px1 < bx2) and (px1 > bx2)

Hi. How can px1 be both smaller and bigger than the same value?

I think you meant...
