Hello,
I am currently programming a game in which you run around in 3rd person view of the player, and i had the code for collision detection and jumping etc. set up in subroutines, so my main "do-loop" would not be as messy. I also have some subroutines, that i use in different situations, so they require some parameters.

Yesterday i converted those subroutines to functions (because of the parameters). The code still works, but whenever i walk (so i use the functions) it is much slower and laggyer.

Can anyone please give me advice on how to avoid that, or if the functions ARE the problem?

(if you need to see the code specificly, i could send you, it is very long though)

Thank you,
Maxi

We'd have to see the functions and how they're called in order to help you. Functions are normally equal in performance though.

We'll have to see some code to know why.

Functions are a tad bit slower. If you pass arguments to the function it gets significantly slower. With that said though they are still ridiculously fast, especially with the computers we have today. There's no way you'd notice any difference.

It's more important to have good structure in your code than speed.

Functions are in fact slower than subroutines same as arrays are slower than simple variables but unless you are trying to squeeze every ounce of speed out of a specific task for example a FloodFill function it doesn't matter.

I got the problem sorted out;
it was that i tried to call a function as a subroutine, what didn´t give me an error, just made everything way slower :/

Thank you anyway for your help, thats still good to know in the future
