Purpose:
- Use as a base for platformer
- Create most of the game in Tiled map editor
- With minimal code changes

You can also run a local server with a fixed port. Then the other instance can't use the same port. (The code is just proof of concept) local socket = require"socket" local s, err = socket.bind("0.0.0.0", "8329") local role = err == "address already in use" an...

Thanks, changed it accordingly
Anyway sorry devdev

There is no possibility of NaN, (y1 > y) ~= (y2 > y) is false for y1 = y2

Your other points are right

Since you use +1 and -1, wouldn't "return wn ~= 0" be sufficient.

pgimeno's code after further simplification -- By Pedro Gimeno, donated to the public domain function isPointInPolygon(x, y, poly) local x1, y1, x2, y2 local len = #poly x2, y2 = poly[len - 1], poly[len] local wn = 0 for idx = 1, len, 2 do x1, y1 = x2, y2 x2, y2 = poly[idx], poly[idx + 1] if (y1 > y...

I recently tried something similar local function shoveItemTo(self, other, x, y) map.world:update(other, x, y) local newx, newy = map.world:check(other, x, y) if newx ~= x or newy ~= y then map.world:update(other, other.x, other.y) else other.x, other.y = x, y end end basically I check if the new po...

Why do every function in graphics.lua check for graphics.isCreated before the actual love.graphics function call? Wouldn't something like this be more optimal? (I mean not this particular code but calling love.graphics functions directly) local lg = _G.love.graphics local graphics = { isCreated = lg...
