for people who want to make a timer but are having a hard time simply add this to your update function and you will have a variable that counts the seconds EDIT: the delta variable (delta = 0) is created in the load function delta = delta + 1 if delta % 59 == 1 then seconds = seconds + 1 end

To generate truly random numbers, you can insert math.randomseed(os.clock()) before inserting button.x = math.random(0 + button.size, love.graphics.getWidth() - button.size) button.y = math.random(0 + button.size, love.graphics.getHeight() - button.size)

The distance formula is derived from a^2 + b^2 = c^2, which shows the relationship between the sides of a right triangle.

[@david8776]

In line 28, when you're invoking the distanceBetween() function you used love.mouse.getX /Y () . But couldn't you just use the parameters x and y as their arguments have already been set to the mouses coordinates?

[@Challacade]

Yep, it would have been better to simply use the parameter values instead. Slight oversight there, but it still works.

Nice one Kyle. Looking forward to a sale on Udemy, so I can afford your Lua course on there. Having dabbled with C# and Visual Basic it seems that Lua shares a lot of similarities. Look forward to doing more in Lua with the Love engine.

[@josuecabralmatos2267]

Hey everyone, some people has been saying "Can you also use Visual Studio Code for Love2D?". Well, kinda but you don't need Love2D for it to work just write down the code and download something called Live Server on Visual Studio Code. Then, you can see your game if there is any problems there it is people.

[@Challacade]

I'm not familiar with Corona Similulator. But, the code you're using there uses LOVE functions (love.draw, love.graphics), but you aren't running your code through LOVE. If there is some kind of Love2D library for Corona where you can execute your code through LOVE, that would work. But you can't run this code alone, it needs to somehow be run with love.exe

Kyle what is your personal preference? Love or monogame? I’m debating between the 2, for a Roguelike or open world tilemap type game

[@Dragon_2011]

Kyle Schaub performance wise would there be much difference on medium sized 2d games between monogame and love? Would it hold up on large tilemap games (in chunks) and not just small one screen leveled games?

[@Dragon_2011]

Kyle Schaub great reply thanks! Will probably pick up your Udemy course for basic love/lua learning. Open world where there are thousands of tiles will be a new challenge for me. I’ve done scrolling tricks where only the visible tiles get drawn, but those worlds weren’t that big. I’ve seen methods where people load 9 screens worth of map, with you being in the center section always, and unload the ones that fall out of range. Not sure how hard keeping stutter out with that would be while loading, but I’ll probably give that a shot with love2d. Drawing to a SpriteBatch would be best I would assume.
