Ryosuke Posted January 19, 2017 Posted January 19, 2017 (edited) Hi, I really need some help! To adjust the speed of sound with the RPM of the vehicle, can anyone help me? local sound = {} function updateEngineSound() local allVehicles = getElementsByType("vehicle") for index, veh in ipairs (allVehicles) do local model = getElementModel(veh) if model == 411 then if getVehicleEngineState(veh) then if isElement(sound[veh]) then local gear = getVehicleCurrentGear ( veh ) or 1 local velocityX, velocityY, velocityZ = getElementVelocity(veh) local actualspeed = ((velocityX^2 + velocityY^2 + velocityZ^2)^(0.5)) * ((11 - gear) /10) local mph = actualspeed * 70 * 111.847 local minSoundSpeed = 0.15 local soundSpeed = mph/(1000+1000/minSoundSpeed) + minSoundSpeed setSoundSpeed (sound[veh], soundSpeed) else local x, y, z = getElementPosition(veh) sound[veh] = playSound3D("sounds/engine.wav", x, y, z, true) attachElements(sound[veh], veh) end else if isElement(sound[veh]) then destroyElement(sound[veh]) end end end end end addEventHandler("onClientPreRender", root, updateEngineSound) Edited January 19, 2017 by Elvis wilian
