I wrote a system for my tilebased rpg which does the following: First get a list of all the visible light sources in the scene. I have a max light distance somewhere, and if the light sources are further away than that from what is visible to the player, I can just ignore them. Then loop through eve...

Check out Axis Aligned Bounding Box collisions (eg. https://www.youtube.com/watch?v=ghqD3e37R7E ) - your player and NPCs will probably be square-ish, and this is one of the simplest and cheapest collision checks you can run in terms of processing power.

You can get the coordinates of where they actually intersect without having to calculate slopes by using cross product ( https://en.wikipedia.org/wiki/Cross_product ). Throw this function two lines in the form L1 = { X1 = 0, Y1 = 0, X2 = 1, Y2 = 1 } etc. GetIntersection = function( L1, L2 ) local d ...

$5k = 4 people @ $25/hour for about a week. I can guarantee you that you will not make an MMO, with 1 coder, in a week. When you take other peoples money through a crowdfunding campaign you are making them a promise that they will get something in return. You will either not be profitable and burn o...

We had a similar issue in this forum post, where there was a bug in how the Voronoi cells would be determined for certain seeds and sizes: https://love2d.org/forums/viewtopic.php?f=5&t=81092&p=191346#p190177 If i remember correctly, the data is; points > make up lines > make up polys so line...

https://love2d.org/wiki/ImageData:getPixel Get the image you're pointing to and check the alpha-component of the pixel where your mouse is pointing in that image. It totally works, I've used it for an adventure-type game (that I didn't finish). And as @rhughes suggests, you need to keep track of whi...

class() isn't a keyword in Lua - you're probably following a tutorial that requires some additional code. Here's a basic way to get a class working. Read the whole thing, and try running it on its own if you can: -- basic class stuff npc = {} npc.__index = npc npc.New = function( ) local newNPC = { ...

I really love Love2d, and I'm excited that I'm getting to a point where I can start throwing stuff at friends for testing. There are some features which can make distributing Love2d-based games easier: • love.filesystem - support for writing files into the root folder (and subfolders) of main.lua. T...

I'm 35, started programming at age 30. Got hired as a game systems designer for an MMO in 2008, started programming after a while to audit the massive amounts of data that an MMO contains. My background is completely unrelated to both gamedev and programming - I went to university to study molecular...

I would recommend using a table of breakpoints rather than a formula. This is way more readable and gives you better control for balancing. Few people have the math chops to look at a formula like math.floor( math.log10( popSize ) ^ 2.75 ) and intuit what a population of 7,000 would give you - I cer...
