Sure:

Although you shouldn't have to directly set the position when using physics, in case of specific needs such as teleports etc. you can use this function.

You can use a generic or a specific Lua library to handle other filesystem calls. That is, using LÖVE you are not constrained to use its functions alone.

However using a generic filesystem handling library comes with some issues such as different OS etc.

I understand your lib resizes fullscreen graphics based on the target display resolution, is that correct? (I don't need a window mode) Yes, that is correct. Perhaps I will say the same thing again, but I am afraid if there is my misunderstanding due to my English skills, so I write the following d...

That might be, but if we are talking post 2012+ laptops that should not happen, if other e.g. graphics intensive operations are not taking place.

Thanks, I am using https://github.com/Vovkiv/resolution_solution right now, but will check yours.

I would say, the time spent on coding depends on if you are using a previously created engine (or a loosely bundled bunch of libs) or straight up from scratch. I would say the coding is definitely more time intensive than 40%. But also I am not so good with graphics, so I tend to go with simpler pro...

Try using this instead in your love.update() function:

Alright, I misunderstood that as an open question.

Looks like a microoptimization to me.

It's rather a programming style question.
