Location extends handle
Handles leak
Even if you clear them, using Reals for the position of the unit is more efficient

 

[Vinz]

Oh. Same pros and cons. What a life. Hassle.

 

[Malhorne]

Yep location are slower, and you have to remove them, ect...
Better use reals coordinates

 

[xAerox]

Straight set coordinates of a unit? "local real x = GetUnitX()" < Like this?

 

[Malhorne]

Yup

"Never use location"
how to get Z of the location without a location? XD

 

[Malhorne]

Ah yes ^^'
Sorry forgot that one \o/
Unless you don't want the Z coordinate never use them ^^

 

[T. D. W.]

function GetCoordinatesZ takes real x, real y returns real
    local location L = Location(x,y)
    local real z = GetLocationZ(L)
    call RemoveLocation(L)
    set L = null
    return z
endfunction

 

[Malhorne]

Yep that works.

 

[T. D. W.]

Omg, i wrote lovation instead of location xD
And i use this in KB3D

 

[chobibo]

Don't dynamically create the locations, just use a global location and move it when you need to get another unit's location:

native MoveLocation takes location whichLocation, real newX, real newY returns nothing

 

[T. D. W.]

It's just a function ^^'
It would've been different in a library or a map

 

[chobibo]

I know it is, but it would be costly to use that.

 

[T. D. W.]

globals
    Location L
endglobals

function GetCoordinatesZ takes real x, real y returns real
    local real z
    set L = Location(x,y)
    set z = GetLocationZ(L)
    call RemoveLocation(L)
    set L = null
    return z
endfunction

Like that for example?

 

[chobibo]

Not like that, you create the location on map init, then you use MoveLocation to move the position to that said location.

globals
    location L
    // constant location L=Location(0,0) // I forgot if this works?
endglobals

function GetCoordinatesZ takes real x, real y returns real
    call MoveLocation(L,x,y)
    return GetLocationZ(L)
endfunction


// Not needed if allocating locations on map init is possible
function MapInit takes nothing returns nothing
    set L=Location(0,0)
endfunction

 

[T. D. W.]

Or that, yes, but mine works too :3 xD
And i think you need to create the location, constant or not, you're moving a null location, so it's location L = location(0,0) constant may work, but i'm not sure

 

[chobibo]

Or that, yes, but mine works too :3 xD

I never said it didn't work, I said it could potentially ruin your game by lagging it because of the overhead when you allocate and deallocate the location...

And i think you need to create the location, constant or not, you're moving a null location, so it's location L = location(0,0)

constant may work, but i'm not sure

It's not a null location, 0,0 is a valid coordinate.

Tests > Opinion

I'm not moving a null location, where was the null location?

 

[T. D. W.]

Nevermind nevermind nevermind, i didn't see the OnInit thing xD

 

[Malhorne]

You can create it but constant location don't work I think.

Yes use chobibo's way is more efficient.

 

[chobibo]

It's not the most efficient though dude haha xD, inlining it would be far more better.

 

[Malhorne]

Just said it was more efficient
That's why I'm found of textmacros ^^ -> INLINE FTW XD

 

[chobibo]

Oh yeah, I've misread. Pardon me haha xD

 

[Malhorne]

No problem at all my chobibro !
