int PackShorts(int short1, int short2)

Packs two short integers (-32768 to 32767) into one integer and returns the result. The short integers must be in the [-32768, 32767] range.

The packed values can be retrieved using UnpackShorts.

// Pack rounded 2D actor positioninto a single integer.
int packed = PackShorts(12345, -15000);
UnpackShort1(packed) -> 12345
UnpackShort2(packed) -> -15000

Passing a 2D actor position to a script:

function void SomeFunction(void)
{
    // Pack rounded 2D actor position into a single integer.
    int pos = PackShorts(GetActorX(0)>>16, GetActorY(0)>>16);
    ACS_ExecuteAlways(somescript, 0, stuff, stuff, pos);
}

script somescript (int stuff, int stuff, int pos)
{
    // Extract actor position
    int x = UnpackShort1(pos);
    int y = UnpackShort2(pos);
}
