pawn Код:

new wannajump[MAX_PLAYERS];

the command(i am assuming you are using ZCMD, i can change that later if you want)

pawn Код:

CMD:togglekeystate(playerid, params[])
{
    if(wannajump[playerid] == 0)
    {
        wannajump[playerid] = 1;
    }
    else if(wannajump[playerid] == 1)
    {
        wannajump[playerid] = 0;
    }
    return 1;
}

In the keystate

pawn Код:

if (PRESSED(KEY_JUMP))
    {
     if(wannajump[playerid] == 1) {
        new
            Float:x,
            Float:y,
            Float:z;
        GetPlayerPos(playerid, x, y, z);
        SetPlayerPos(playerid, x, y, z + 5.0);
    }
