Snippet R-Functions

[Rheias]

Just a few simple function to help you do things faster - I'll keep this updated since every function that I will write and find useful I'll add here.

// if SubString(l-1,l) is just annoying
function RF_IsEven takes integer subject returns boolean
    local integer check = subject / 2
    local integer test = check * 2
    
    if test < subject or subject < 2 then
        return false
    endif
    
    return true
endfunction

function RF_R2I takes real subject returns integer
    local real check = subject - .5
    local integer test = R2I(subject)
    
    if test >= check then
        return test
    endif
    
    return test + 1
endfunction

// Too bad we can't return two reals
function RF_Destination takes unit subject, real wait returns location
    local real facing = GetUnitFacing(subject)
    local real speed = GetUnitMoveSpeed(subject)
    local real distance = wait * speed
    local location current = GetUnitLoc(subject)
    local location returned = PolarProjectionBJ(current,distance,facing)

    // Leakz
    call RemoveLocation(current)
    set current = null
    
    return returned
endfunction

//Forced by WE - Not relevant
function InitTrig_RFunctions takes nothing returns nothing
endfunction

RF_IsEven - If an integer is even it will return true, else return false. 0 is considered odd (false).

RF_R2I - Converts a real to integer, however unlike the regular conversion, it won't be rounded down, but rounded to the closet integer (e.g. 3.1 = 3, 3.7 = 4). X.5 = X.

RF_Destination - Assuming the unit will keep walking in the same direction this will return the location it will reach after "wait" number of seconds.

Very little so far, but I hope soon enough more functions will be added, anyway, have fun with it.

>>X.5 = X
arent .5 being rounded will become 1?

 

[Rheias]

What?

1.5 = 1 if you use my function. In the same manner:

2.5 = 2, 3.5 = 3, 4.5 =4 ... n.5 = n

 

[AceHart]

return (number / 2) * 2 == number

return R2I(number + 0.5)

Unverified...

Hmmm... Care do explain what you want to say in that post?

> Unverified

Are you quite sure this is a legitimate word?

 

[AceHart]

That there's most likely an easy way to shorten those functions to one-liners.

Yes.

> That there's most likely an easy way to shorten those functions to one-liners.

Bah - those are too simple for my mind which likes to do things more complicated than they should.

> Yes.

Then it is not included in my dictionary.

 

[~GaLs~]

my meaning is...

0.0, 0.1, 0.2, 0.3, 0.4 should be 0 when being rounded
0.5, 0.6, 0.7, 0.8, 0.9 should be 1 when being rounded...

 

[phyrex1an]

Off topic.

Then it is not included in my dictionary.

See verify.

> 0.5, 0.6, 0.7, 0.8, 0.9 should be 1 when being rounded...

Then change the function, although AceHart pretty much ruined what I did here.

> See verify.

Bah, I tried verifie, thanks phyrex1an, you learn something new every day.

 

[Master]

Well nothin's ruined...it's quite good, Rheias +rep.

You are incompetable.

Look in dictionary -> incompetability

This can be accomplished very simply using the mod function.

if (<Number> Mod 2) Equal to 0, Then
  return true
else
  return false

That just seems a little simpler.
As for the other stuff, looks pretty good.

 

[AceHart]

> That just seems a little simpler.

Once there, you notice that, basically, you're returning the result of the test, so you return the test directly and forget the "if".
At which point you can do the mod yourself, and end up with post #4.

 

[Rheias]

My function (IsEven) is basically a (very) fancy way of doing AceHart's job. As for your function, it may be a bit shorter (note that my function is long in order to make it clear) but I'm not sure it is efficient as mine (no function calls in mine, in yours there is one,which is quite slow).

Anyway, this is supposed just to be kind of a bank for functions, I hope the next ones would be more useful.

RF_IsEven - If an integer is even it will return true, else return false. 0 is considered odd (false).

I'ld use

if subject - (subject / 2) * 2 == 0 then

.

EDIT: didn't read aceharts post, sorry.

EDIT2: You can aswell write these functions in your map header. Then you aren't forced by WE to make a trigger init function. On second thought - in which way does WE force you to copy the WHOLE page, and not to skip the last two ( three ) lines?
