The contents of your uploaded main.lua do not match the code in your opening post, since you replaced the repeat-until with a goto, but... local queue = { { 1 } } local bananas = { 'got nil?' } function func(o) love.graphics.print(o[1]) end -- inside the loop for _, o in pairs(queue) do func(bananas...

Okay, I'll take just this snippet, and step you through it: local i = 1 repeat if queue[i] then for _, o in pairs(queue[i]) do o:func(bananas[i]) end end i = i + 1 if i < (999 + 1) then bananas[i * i / i] = nil end until(i > 5) 1. The code starts a repeat-until loop, ok. 2. If queue table at index i...

Can you share some code, to illustrate the problem you are having? The part about losing the metatable in the process sounds odd. Do remember that the colon(:) syntax is just syntactical sugar: myObject:myFunction(arg1) -- is the same as myObject.myFunction(myObject,arg1) function myObject:myFunctio...

The function I already posted handles deep copies, but it's not the only implementation to do so. The main caveat is that it may not work on tables that have any sort of special metatables going on, or extremely deep tables. However, based on the roblox docs, I believe Kopelat might just need to loo...

There are clone functions for a couple of specific types of things in löve, like Source:clone for audio sources. However, based on what I can surmise from Roblox documentation , you're asking for a method to create copies of lua objects. There is no readily available built-in functionality for this,...

Thanks for the heads up, I don't actively use macOS, so I didn't quite realize that issue with the threads (truth be told, the threading is some ancient legacy code that could use an overhaul). I was turning JIT off on MacOS on the main thread, due to some potential luajit issues . Will look at addi...

In lua, # is the length operator. It returns the length of a string or table. I recommend looking up what the reserved keywords and operators are. PIL (the manual I linked) is a good resource to read through if you want to learn lua.

Ah, right. That's simply because you add the character to the world with this: world:add(player,player.x+1,player.y+1,player.width-2,player.height-2) But then you move the character with this: local goalX = player.x + (player.speed*player.xdir*dt) local goalY = player.y + (player.speed*player.ydir*d...

Can you provide a .love of your project? I believe I would need to see your project in action to properly diagnose what the problem is, because I don't see anything wrong with the bump code.

Yeah, filters are the bread and butter of how to make your bump objects behave the way you want them. If you tried to pass bounce as an underfined variable (global or otherwise), or leave the parameter empty (nil), bump will register any and all collisions. Depending on the type of function, these c...
