for example, i have an equation in my script
Code:
X := 1
Y := X**2 + 3*X + 10


i want it to look complicated so even ppl read it, they wont understand and hesitate to modify the script. but on the other hand, the function needs to be call frequently (few times per sec and a lot longer that the example equation, i am dealing with vectors and coordinates), so i dont want to affect the performance that much

i am thinking something like:
Code:
X := 1
A := sqrt(100)
Y := X**(2*sin(1.570))
D := Y + Mod(7,4)*X + A
 


what about hex calculation or NumPut, what do u guys think?

the script are read by normal ppl (leechers.....), so dont expect them to be as experienced as u guys. so the above example should stop most ppl, but just want something more complicated to stop more ppl

The ternary operator can be confusing for people who don't understand programming. Maybe something like this:
Code:
X:=NumGet(&x,0,"UInt")+32>>5 ; If X is blank, this is the same as 0 + 32 / 2**5
Y:=SubStr(Round(4*ATan(1),16),2,1)="." ? X+x*x+10+X*2:<put whatever expression here - it won't matter>


Note - the test part of the ternary operator checks if the 2nd character of PI is a decimal. Also, it would be fairly easy to put some more ternary operators (& nested ternary operators) to make it look confusing.

....it does look confusing (even after i check help file)
ok, i think i will go with NumGet, BitShift and Ternary operator
thank you

thanks also
i wasnt looking for something that complicated that requires multi-script or modification on the syntax of the compiler or jump around using goto...
but because of the searching, i did get a new idea from a user's signature
Code:
vPhiLho := RegExReplace("Philippe Lhoste", "^(\w{3})\w*\s+\b(\w{3})\w*$", "$1$2")


i heard it is slow using regex, but wasnt that bad, everything less than 1ms is fine with me

RegEx likely won't work for the purposes of math functions, it's meant for advanced string matching and replacing.

it seems work
Code:
NewStr := RegExReplace("abc123", "i)^ABC") + 2 ;123+2
msgbox, % NewStr

Code:
3dvector := asc("{Bumpmapping(Object,shadermodel:=(Directx11.handler))}")
DLLCache := asc("? * random(nonsense) > DEVICE NULL")
;
; you can hide actual numbers in asc("string"), will only return the first character in the string as
; a numerical ASCII value, {=123 and ?=63 , the rest of the strings are pure nonsense

UseReversePolishNotation := chr((9471/3dvector))
Beziercurve1 := chr(79)
Z_Plane := chr(68)
;
; Likewise you can hide characters as numbers, CHR(9471/123=77)="M" + CHR(79)="O" + CHR("68") ="D"  "Mod", modulus function, many people recognize standard asci tablenumbers in alphabet range so the "M" from mod is calculated from already fuzzed  number
;
GetFrom = %UseReversePolishNotation%%BezierCurve1%%Z_plane%
;
; Bring it all together in uebergeeky function:
;
Msgbox % 3dvector %getfrom% (DLLCache)  ; or even use in a regex
