Try this:

pawn Код:

if(GetPlayerState(playerid) == PLAYER_STATE_SPECTATING)
{
    if(newkeys == KEY_HANDBRAKE)//Right Mouse
    {
        ReverseSpectate(playerid);
    }
    if(newkeys == KEY_FIRE)//Left Mouse
    {
        NextSpectate(playerid);
    }
}

https://sampwiki.blast.hk/wiki/GetPlayerKeys explains that "KEY_AIM is undefined in SA-MP includes. You can either define it yourself or use KEY_HANDBRAKE."
