从.net发送反馈/效果到操纵杆
感谢这个答案https://stackoverflow.com/a/13734766/637142我能够知道按下按钮的时间或旋转方向盘的时间。 现在我的问题是如何将效果发送到设备？ 例如，当我正在玩游戏时，如果我发生碰撞，车轮会振动。 我怎么能让方向盘振动？
我相信我需要做的是Start()一个效果（ http://sharpdx.org/documentation/api/t-sharpdx-directinput-effect ）。 SharpDX.DirectInput.Joystick类似乎没有一个方法可以返回所有效果。 有一个名为GetEffects的方法，但该方法返回一组EffectInfo对象。 游戏如何向操纵杆发送命令？
源代码从此处复制粘贴。
要使用此源，您需要一个“ 强制效果文件 ”（ C：\ MyEffectFile.ffe ），以在操纵杆上“播放”它。
根据本书创建的“强制效果”文件，您需要使用DirectX SDK附带的“ 强制编辑器 ”。
（同一本书，或者说，你可以在代码中从头开始创建效果……在答案中，我发现另一段代码创建并起诉效果而不从文件中加载它:-)）

我刚刚在这里找到了另一段可能有用的代码。 此示例似乎从头开始创建效果，因此您不需要“效果文件”。
DeviceList xDeviceList = Manager.GetDevices(DeviceClass.GameControl, EnumDevicesFlags.AttachedOnly); DeviceInstance someDeviceInstance; foreach (DeviceInstance deviceInstance in xDeviceList) { someDeviceInstance = deviceInstance; break; } Device someDevice = new Device(someDeviceInstance.InstanceGuid); someDevice.SetCooperativeLevel(this.Handle, CooperativeLevelFlags.Exclusive | CooperativeLevelFlags.Background); int[] axis = new int[0]; foreach (DeviceObjectInstance doi in someDevice.Objects) { if((doi.Flags & (int)ObjectInstanceFlags.Actuator) != 0) { axis = new int[axis.Length + 1]; axis[axis.Length - 1] = doi.Offset; } } someDevice.Acquire(); Effect effect = new Effect(); effect.SetDirection(new int[axis.Length]); effect.SetAxes(new int[axis.Length]); effect.ConditionStruct = new Condition[axis.Length]; effect.Flags = EffectFlags.Cartesian | EffectFlags.ObjectOffsets; effect.Duration = int.MaxValue; effect.SamplePeriod = 0; effect.Gain = 10000; effect.TriggerButton = (int)Microsoft.DirectX.DirectInput.Button.NoTrigger; effect.TriggerRepeatInterval = 0; effect.UsesEnvelope = false; effect.EffectType = Microsoft.DirectX.DirectInput.EffectType.ConstantForce; effect.StartDelay = 0; effect.Constant = new Microsoft.DirectX.DirectInput.ConstantForce(); effect.Constant.Magnitude = -5000; EffectObject effectObject = null; foreach (EffectInformation ei in someDevice.GetEffects(EffectType.ConstantForce)) { effectObject = new EffectObject(ei.EffectGuid, effect, someDevice); } effectObject.SetParameters(effect, EffectParameterFlags.Start );
这里是另一个链接，然后可能是有用的力反馈样本
