MathUtil is pissing me off

import funkin.backend.utils.MathUtil;

MathUtil.max(a, b, c, d, e) // Null Object Reference
MathUtil.maxSmart(a, b, c, d, e) // Null Function Pointer
MathUtil.maxInt(a, b, c, d, e) // Null Object Reference

I'm at a loss for words. All three of these functions exist within MathUtil and the wiki, but none of the work in HScript. I'm on v1.0.1, and I'm using this in a ModState. I really don't want to nest Math.max's, and the function ought to work anyway. Please help!

Extra context: I'm trying to make a slicesprite that

• isn't shit for performance (thanks for that, Flixel)
• is usable outside of UIState.

Also, I recall trying to use MathUtil.max and MathUtil.maxSmart in a different project in CNE, but they didn't work then either.

max returns the highest float provided by the set of variadic arguments. For example, if you were to provide the arguments 10.0, 18.0, and 2.0, 18.0 would be returned.

maxInt does the same thing, but instead operates on and returns integers.

maxSmart only works during compile-time, not in HScript. That's the reason why there's a @dox:(hide) tag on the function, which causes it to be hidden from the API documentation when performing documentation generation.

Thank you for that. I will emphasize that I know what the functions do (aside from MathUtil.maxSmart, I didn't know that one didn't work in HScript, so thank you). I was confused as to why MathUtil.max/maxInt don't work and return Null Object References and how I can make them work without nesting Math.maxs.

max operates on floats, so you have to ensure that whatever you're passing to it can actually be used as a float. The same goes with maxInt, but with integers.

What happens if you only pass in one argument?

what?? hold on I'm gonna answer this in parts

max operates on floats, so you have to ensure that whatever you're passing to it can actually be used as a float. The same goes with maxInt, but with integers.

I understand this

What happens if you only pass in one argument?

I don't know; you probably get that argument back since it has the max value of the arguments (it being the only one)

Here, I'll just demonstrate what I'm doing and what's happening when I try it.

Here's some sample code of what I'm basically trying to do:

And here's what console is spitting out:

Also, yes, I did import MathUtil:

Why is it doing this and how can I fix it??

For your information, hscript-improved has the following limitation, which doesn't appear to be addressed:

only one variable declaration is allowed in var

You likely need to split the variable declaration into separate var statements to ensure that you don't have issues with variable declarations. So, you will likely need to change lines 75 to 78 to the following:

var a = 9;
var b = 1.29378;
var c = Math.PI;
var d = 91273883.222;

only one variable declaration is allowed in var

Ahhh ok that makes sense yeah that's a problem uhhh cool thank you
also, comma var declaration does work in hscript. Try it sometime it's kinda neat
