#define and math formula

[[frl]myke 14]

Hi folks,

i'm doing something and i'm not sure if i did it correct. Don't say "try it out" as it will take some time unless the work will be ready even only for test, so i guess i get faster answers (also if it takes a few days) if i put it in here.

Basically it is about #define and based simple math formula with defines.

#define warheadHit	20
#define	warheadIndirectHit	8.5
#define	warheadIndirectHitRange	1
#define warhead	9.4


	hit = "warhead * warheadHit";
	indirectHit = "warhead * warheadIndirectHit";
	indirectHitRange = "warhead * warheadIndirectHitRange";

These are just small snippets so yes, i know there is class cfgAmmo stuff missing, but this is not the topic here so i've posted only the relevant parts.

As you see, i've defined some constants and used them to do simple multiplications with it. I just need to know if it's done correctly or not.

Thanks for your time and happy easter.:D

Defines are not replaced inside strings that are double quoted.

I think it should either be:

hit = warhead * warheadHit;

or:

hit = __EVAL(warhead * warheadHit);

Thanks Sickboy.

Could you explain the __EVAL a little more? I'm not familiar with this kind of programming and in the BIWIKI there isn't any useful (at least for me) explanation.

__EVAL forces the line to be evaluated at preprocess time. That way your math expression gets interpreted and the result used instead.

@TRexian

i knew this site but for me with no programming knowledge beyond sqs/sqf scripting and surplus not being native english, this page could be written in traditional chinese aswell.

Would be cool if google translate could work on code... :D
