[Threshold]

Oh my god... I don't know how I missed it... you were putting the 'forcesync' parameter in place of the 'timer' parameter.

Код:

ApplyAnimation(playerid, animlib[], animname[], Float:fDelta, loop, lockx, locky, freeze, time, forcesync)

pawn Код:

ApplyAnimation(playerid, "BD_FIRE", "wash_up", 4.0, 0, 0, 0, 0, 0, 1);

Meaning time = 1, which means the animation would stop playing after 1 millisecond...

Use this:

pawn Код:

CMD:lock(playerid, params[])
{
    if(!GetPVarInt(playerid, "LoggedIn")) return SendClientMessage(playerid, COLOR_RED, "[ERROR]: You need to be logged in to use this command.");
    for(new i = 0; i < MAX_HOUSES; i++)
    {
        if(!fexist(HousePath(i))) continue;
        if(IsPlayerInRangeOfPoint(playerid, 2, House[i][ExtPosX], House[i][ExtPosY], House[i][ExtPosZ]) || IsPlayerInRangeOfPoint(playerid, 2, House[i][IntPosX], House[i][IntPosY], House[i][IntPosZ]))
        {
            if(Player[playerid][HouseID] != House[i][hID]) return SendClientMessage(playerid, COLOR_GREY, "You don't own this house.");
            new string[60];
            ApplyAnimation(playerid, "BD_FIRE", "wash_up", 4.0, 0, 0, 0, 0, 0, 1);
            format(string, sizeof(string), (House[i][hLocked]) ? (" * %s unlocks the door to the house.") : (" * %s locks the door to the house."), GetName(playerid));
            SetPlayerChatBubble(playerid, string, COLOR_LIGHTPURPLE, 10, 7000);
            SendClientMessage(playerid, COLOR_LIGHTPURPLE, string);
            House[i][hLocked] = (House[i][hLocked]) ? (0) : (1);
            break;
        }
    }
    return 1;
}
