Float:Angle2D(Float:PointA[], Float:PointB[]) warning but I don't get it why... - Scrillex - 26.03.2013

pawn Code:

warning 208: function with tag result used before definition, forcing reparse

pawn Code:

Float:Angle2D(Float:PointA[], Float:PointB[])
{
    new bool:A_LS_B[2], Float:Dist[2], Float:Angle;

    for (new i = 0; i < 2; i++)
    {
        A_LS_B[i] = PointA[i] < PointB[i];
        Dist[i] = A_LS_B[i] ? PointB[i] - PointA[i] : PointA[i] - PointB[i];
    }

    Angle = atan2(Dist[1],Dist[0]);
    Angle = A_LS_B[0] ? 270.0 + Angle : 90.0 - Angle;
    Angle = A_LS_B[1] ? Angle : 180.0 - Angle;

    return Angle;
}

When you put a tag on a function (Float: in this case) the definition of the function must come before the function is called, IE put it at the very top or in an include.

I don't exactly know why this happens, I'm sure someone who knows the compiler can tell you why but, for now the above will fix the warning.

If im not wrong you cant use a new function with the starter a Float:

isnt it supposed to be like:

pawn Code:

stock Angle2D(Float:PointA[], Float:PointB[])

EDIT: nvm i was wrong :$

You can put tags on functions, but they must be defined before they are called. You can't have a function with a tag at the bottom of your code and call it in OnGameModeInit w/o this warning for example.

EDIT: Just saw your edit

Just it's strange why it's happening.. Now I puted on top ofthe script.. lets see if it will work just it's in yom buttons.. I don't want to mess include up!

i'm not sure but try this

pawn Code:

Float:Angle2D(Float:PointA[], Float:PointB[])
{
    new bool:A_LS_B[2], Float:Dist[2], Float:Angle;

    for (new i = 0; i < 2; i++)
    {
        A_LS_B[i] = PointA[i] < PointB[i];
        Dist[i] = A_LS_B[i] ? PointB[i] - PointA[i] : PointA[i] - PointB[i];
    }

    Angle = atan2(Dist[1],Dist[0]);
    if(Angle = A_LS_B[0]) ? 270.0 + Angle : 90.0 - Angle;
    if(Angle = A_LS_B[1]) ? Angle : 180.0 - Angle;

    return Angle;
}

Everything worked when I puted in top of the script

but it's just interesting why its like that!
