1) ApplyAnimation(playerid,"PED","SEAT_IDLE",4,0,0,0, 1,0,1); not sure but 'by searching i found that'
2 ) make an variable once the player used the animation example

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    //check if the variable of the animation == 1 
    if (PRESSED(KEY_JUMP))
    {
           //do something here!
    }
    return 1;
}
