[SnipeZz_Qc]

Hy guys im trying to make a drug script but I can't get work the duration of the drug.

here is the script:

private ["_item","_config","_timeOut","_timeMax"];
_item =    _this;
_config = configFile >> "CfgMagazines" >> __item;
_hasdrug1kg = _this in magazines player;
_text = getText (_config >> "displayName");
_timeOut = 0;
_timeMax = 30;
dayz_lastCheckBit = time;
drug1k = 1;
disableSerialization;
 
    player removeMagazine _item;
    player playActionNow "PutDown";
    sleep 1;
    //_nul = [objNull, player, rSAY, "playerSnoring"] call RE;
    while {drug1k == 1} do {
        switch true do {
            case (_timeOut < _timeMax) : {
                "chromAberration" ppEffectEnable true;
                "chromAberration" ppEffectAdjust [_force / 24, _force / 24, false];
                "chromAberration" ppEffectCommit (0.3 + random 0.1);
                waituntil {ppEffectCommitted "chromAberration"};
                sleep 0.6;
        }; 
            default {
                sleep 3;
                "colorInversion" ppEffectEnable false;
                "wetDistortion" ppEffectEnable false;
                "colorCorrections" ppEffectAdjust [1, 1, 0, [0.5,0.5,0.5,0], [0.5,0.5,0.5,0], [0.5,0.5,0.5,0]];
                "colorCorrections" ppEffectCommit 10;
                waitUntil {ppEffectCommitted "colorCorrections"};
                "colorCorrections" ppEffectEnable false;
                "chromAberration" ppEffectEnable false;
                    };
        };
            sleep 1;
            _timeOut = _timeOut + 1;
};
        cutText ["", "PLAIN DOWN"];
