Summary

0004471: Add more math functions to Decorate

Description

I mean

FRandomPick(float[]), RandomPick(int[]),

Cos(float), Sin(float), Tan(float),

ACos(float), ASin(float), ATan(float),

ATan2(float, float) [Alias: VectorAngle(float, float)],

Round(float), Ceil(float), Floor(float),

Min(float[]), Max(float[]), Clamp(float, float, float).

I think it will be easy to implement these functions in Decorate, because C\C++ already has libraries that calculate these functions (except #randompick(#[])).

(0024290) IlyStr (reporter) 2025-03-22 13:17 edited on: 2025-03-22 13:20	And RandomPick is actually many times more necessary than trigonometry and rounding, because here is a comparison of the same function but only using RandomPick and Random GZdoom: RandomPick(64, 192) Za: (128 + ((Random(0, 1)2)-1)64) And this way every function call imitation, the optimization after 3-8 repeats per tic goes somewhere far away...

(0024292) Kaminsky (developer) 2025-03-22 14:07	This won't happen until we upgrade our GZDoom base and backport these functions, which won't be until at least 4.0 or later.
