I am currently working on a combat system and I wanted to be able to have key combos to execute combat moves and such, and I am detecting key input type as well for example, if the key is tapped, or long pressed.

I use this line below to record the time a key is pressed, and time when the same key is released, so I can differentiate whether the key is just a quick tapped or long pressed.

The problem is when I wanted to make a key combination, and I stopped this function, whenever a new Key is pressed, the new key will be considered as a Long Pressed as well. My current codes only able to register input types after the key is released, and I wanted to be able to make a charging combo as well.

For example when I'm holding a Tab and I tap a new different key, both keys will be considered as a Long Pressedwhile the expected result supposed to be Long Pressed Tab key, and the new pressed key is a simple quick tap. If I'm understanding it correctly, you have a single timer but many buttons that could be pressed.

This may sound daunting and gross; but it's quite easy to manage with a map which is called a Dictionary in C or Python.

Then use the keys that you're checking for as the inputs to the map, with the timer being the piece of data being stored. Now you have a constant time! Simply start, stop, and access your timers in the map via the FKey being pressed and voila.

It is used to query virtual or raw controller state, such as buttons, thumbsticks, triggers, and capacitive touch data. It supports the Oculus Touch and Oculus Go controllers. For keyboard and mouse control, we recommend using the UnityEngine. Mobile input bindings are automatically added to InputManager. Controller poses are returned by the tracking system and are predicted simultaneously with the headset.

These poses are reported in the same coordinate frame as the headset, relative to the initial center eye pose, and can be used for rendering hands or objects in the 3D world.

They are also reset by OVRManager.

RecenterPosesimilar to the head and eye poses. Note : Oculus Touch controllers are differentiated with Primary and Secondary in OVRInput: Primary always refers to the left controller and Secondary always refers to the right controller. Whether the controller is visualized on the left or right side of the body is determined by left-handedness versus right-handedness, which is specified by users during controller pairing.

The Back button on Oculus Go only supports the functionality of GetUp as the Back button only reports a change in status during the frame that the button is released. This button does not report a change in status when pressed. For Oculus Go controllers, the user interface of your VR experience should follow these natural scrolling and swiping gestures:.

There are multiple variations of Get that provide access to different sets of controls. These sets of controls are exposed through enumerations defined by OVRInput as follows:. The first set of enumerations provides a virtualized input mapping that is intended to assist developers with creating control schemes that work across different types of controllers. The second set of enumerations provides raw unmodified access to the underlying state of the controllers. We recommend using the first set of enumerations, since the virtual mapping provides useful functionality, as demonstrated below.

When the user makes physical contact, the Touch for that control will report true. When the user pushes the index trigger down, the Button for that control will report true. In addition to specifying a control, Get also takes an optional controller parameter.

The list of supported controllers is defined by the OVRInput. Specifying a controller can be used if a particular control scheme is intended only for a certain controller type. If no controller parameter is provided to Getthe default is to use the Active controller, which corresponds to the controller that most recently reported user input.

For example, a user may use a pair of Oculus Touch controllers, set them down, and pick up an Xbox controller, in which case the Active controller will switch to the Xbox controller once the user provides input with it.In Unreal Engine 4 we wanted to make binding input events as easy as possible. To that end, we created Input Action and Axis Mappings. While it is certainly valid to bind keys directly to events, I hope I can convince you that using mappings will be the most flexible and convenient way to set up your input.

Action and Axis Mappings provide a mechanism to conveniently map keys and axes to input behaviors by inserting a layer of indirection between the input behavior and the keys that invoke it. Action Mappings are for key presses and releases, while Axis Mappings allow for inputs that have a continuous range.

Using input mappings gives you the ability to map multiple keys to the same behavior with a single binding. It also makes remapping which keys are mapped to the behavior easy, both at a project level if you change your mind about default settings, and for a user in a key binding UI.

In the Input section of Engine Project Settings you can see the list of existing mappings and create new ones.

Actions are pretty straightforward: give the action a name, add the keys you want mapped to the action, and specify which modifier keys need to be held when the key is pressed.

Axis mappings are also reasonably straightforward. Instead of specifying any modifier keys, however, you specify a Scale. This is particularly useful for creating an axis out of keyboard keys for example, W can represent pressing up on the gamepad stick while S represents pressing down.

In Blueprints you can place an Axis or Action Event node from the Input section of the context menu or palette of any Actor blueprint. It should also be noted that if you had both W and Up pressed then the value is 2, so you would likely want to clamp the value in the bound function.

However, in the case of Paired Actions actions that have both a pressed and a released function bound to them we consider the first key to be pressed to have captured the action. Have questions?

Privacy policy.The PlayerInput Object is responsible for converting input from the player into data that Actors like PlayerControllers or Pawns can understand and make use of.

It is part of an input processing flow that translates hardware input from players into game events and movement with PlayerInput mappings and InputComponents.

For an example of setting up Input, refer to the Setting Up Inputs documentation. Hardware input from a player is very straightforward.

It most commonly includes key presses, mouse clicks or mouse movement, and controller button presses or joystick movement. Specialized input devices that don't conform to standard axis or button indices, or that have unusual input ranges, can be configured manually by using the RawInput Plugin.

It is only spawned on the client. Two structs are defined within PlayerInput. Map a discrete button or key press to a "friendly name" that will later be bound to event-driven behavior. Map keyboard, controller, or mouse inputs to a "friendly name" that will later be bound to continuous game behavior, such as movement.

The inputs mapped in AxisMappings are continuously polled, even if they are just reporting that their input value. Input mappings are stored in configuration files, and can be edited in the Input section of Project Settings. Change the properties of hardware axis inputs:. Add or edit ActionMappings:. Add or edit AxisMappings:. InputComponents are most commonly present in Pawns and Controllers, although they can be set in other Actors and Level Scripts if desired.

If you want a particular Actor to always be the first one considered for input handling, you can re-enable its "Accepts input" and it will be moved to the top of the stack. This class is the current player's Pawn, so its InputComponent is checked last. Whatever this node is connected to is what will execute when W is pressed.

By default, games running on touch devices will have two virtual joysticks like a console controller. This points to a Touch Interface Setup asset. Note that you will need to check the Show Engine Content checkbox in the object picker View Options settings to see these. If you do not want any virtual joysticks, just clear the Default Touch Interface property. Additionally, you can force the touch interface for your game independent of the platform it is running by checking Always Show Touch Interface or by running the PC game with -faketouches.

When I put Code CSharp :. ShushustormSep 18, ZuntatosSep 18, Joined: Mar 25, Posts: Recently I was working on a very complex user control with lots of child controls on it and wanted to be able to override the handling of the keydown event in a single place the main user control.

I added the keydown event to my user control and noticed that it never got fired.

[SOLVED] Input.GetKey not working (Unity 5.2)

This seemed to be because the child controls were handling them instead and not passing them to the main control. On a form, you can set Form. KeyPreview to True which will allow the form to receive key events before they are passed to the control that has focus. Unfortunately, this is not available on user controls. Some searching on the Internet revealed that the ProcessKeyPreview event which when overridden in a user control will allow you to trap the keyboard messages before the child controls get them.

Unfortunately the ProcessKeyPreview is not very friendly and passes you the Windows messages.

This means you need to know the message number, handle repeating keys, handle control keys, etc. I did a bit of reflecting on the framework and found that it's actually pretty easy to turn the messages into standard keydown and keyup events which makes it much easier to code.

To use the code, simply paste it into your control. Note that the ProcessKeyPreview can return true or false to indicate whether the keypress has been handled. However, if you are not handling it you should defer to the base ProcessKeyPreview method. You can set this in the KeyEventArgs as per usualThank you for helping us improve the quality of Unity Documentation.
