SetTimerEx("Highlight", 2000, true, "i", playerid);

new changed[MAX_PLAYERS] = 0;
forward Highlight(playerid);
public Highlight(playerid)
{
    if(changed[playerid] == 0)
    {
        SetPlayerColor(playerid, 0xFF0000FF);
        changed[playerid] = 1;
    }
    else
    {
        SetPlayerColor(playerid, 0xFF9900FF);
        changed[playerid] = 0;
    }
}

It should be SetTimerEx(); My bad.
