For a particle to be spawned you need to define a particle source (https://community.bistudio.com/wiki/ParticleTemplates) which you can do using this: Heat = "#particlesource" createVehicleLocal getpos player; So with this, you can put it amongst the rest of the code for the heat effect into a .sqf file which I named "HeatEffect.sqf": Heat = "#particlesource" createVehicleLocal getpos player; Heat setParticleCircle [0, [0, 0, 0]]; Heat setParticleRandom [0, [0.25, 0.25, 0], [0.175, 0.175, 0], 0, 0.25, [0, 0, 0, 0.1], 0, 0]; Heat setParticleParams [["\A3\data_f\ParticleEffects\Universal\Refract", 1, 0, 1], "", "Billboard", 1, 12.5, [0, 0, 0], [0, 0, 0.75], 0, 10.3, 7.8, 0.075, [1.2, 2, 4], [[0.1, 0.1, 0.1, 1], [0.25, 0.25, 0.25, 0.5], [0.5, 0.5, 0.5, 0]], [0.08], 1, 0, "", "", XXXOBJECTXXX]; Heat setDropInterval 0.05; interval = 0.05; CircleRadius = 0; CircleVelocity[] = {0,0,0}; particleShape ="\A3\data_f\ParticleEffects\Universal\Refract"; particleFSNtieth =1; particleFSIndex =0; particleFSFrameCount =1; particleFSLoop =0; angle =0; angleVar =0; animationName = ""; particleType = "Billboard"; timerPeriod = 1 ; lifeTime = 12.5; moveVelocity[] = {0, 0, 0.75}; rotationVelocity = 0; weight = 10.3; volume = 7.8; rubbing = 0.075; size[] = {1,1}; animationSpeed[] = {1}; lifeTimeVar = 0; positionVar[] = {0.25, 0.25, 0}; positionVarConst[] = {0, 0, 0}; moveVelocityVar[] = {0.175, 0.175, 0}; moveVelocityVarConst[] = {0, 0, 0}; rotationVelocityVar = 0; sizeVar = 0.25; colorVar[] = {0, 0, 0, 0}; randomDirectionPeriodVar = 0; randomDirectionIntensityVar = 0; sizeCoef = 1; colorCoef[]={0,0,0,0.1}; animationSpeedCoef = 1; destroyOnWaterSurface = 0; destroyOnWaterSurfaceOffset = 0; onSurface = true; keepOnSurface = false; surfaceOffset = 0; bounceOnSurface = 0.6; bounceOnSurfaceVar = 0.0; postEffects = ""; particleEffects = ""; Next you can use this script (imaginatively named "Cloak.sqf"), which you can call from an AddAction, to deal with the cloaking and to spawn the heat effect on the player. I also added in a timer. _Unit = _this select 0; timer = 60; _nil = [] execVM "HeatEffect.sqf"; _Unit hideObject true; SystemChat "Cloak Active"; _Unit setCaptive true; [timer] spawn { while {!(timer == -1)} do { Heat setpos (getpos _Unit); sleep 0.1; }; }; while {!(timer == -1)} do { SystemChat format ["%1 seconds left",timer]; timer = timer -1; sleep 1; }; _Unit hideObject false; deleteVehicle Heat; SystemChat "Cloak Deactivated"; _Unit setCaptive false; I then added an AddAction into the player's init field such that I could call the Cloaking script. this addaction ["Cloak", "Cloak.sqf", [], 6, false, true]; There's probably room for improvement with my code and excuse any errors because I'm new to scripting :p. Here's a video of it in action: Excuse the poor quality, had to compress the video or I would never have been able to upload it with my poor internet speed.

ContainerOpened doesn't seem to work for me either. So I settled for this instead, although I think you said you had tried this method. player addEventHandler ["InventoryOpened", { if (_this select 1 == _obj) then { _unit = _this select 0; _container = _this select 1; hint format ["%1 Opened %2",_unit,_container] }; }];
