from panda3d.core import InputDevice
- class InputDevice
This is a structure representing a single input device. Input devices may have zero or more buttons, pointers, or axes associated with them, and optionally a motion tracker.
These devices are brought under a common interface because there is such a large range of devices out there that may support any number of these types of axes, we couldn’t even begin to cover them with type-specific subclasses.
Use the various has_() and get_num_() methods to determine information about the device capabilities. For instance, has_keyboard() will give an indication that you can receive keystroke events from this device, and
getNumButtons()will tell you that the device may send button events.
There is the DeviceType enumeration, however, which will (if known) contain identification of the general category of devices this fits in, such as keyboard, mouse, gamepad, or flight stick.
New in version 1.10.0.

This enum contains information that can be used to identify the type of input device.
enumerator unknown = 0
It is not known what type of device this is.
enumerator virtual_device = 1
This means that the device doesn’t correspond to a physical device, but rather to a dynamic source of input events.
enumerator keyboard = 2
A physical, alphabetical keyboard.
enumerator mouse = 3
enumerator touch = 4
enumerator gamepad = 5
A gamepad with action buttons, a D-pad, and thumbsticks.
enumerator flight_stick = 6
enumerator steering_wheel = 7
enumerator dance_pad = 8
enumerator hmd = 9
enumerator spatial_mouse = 10
3D mouse, such as produced by 3Dconnexion.
enumerator digitizer = 11
A graphics tablet with stylus/pen.
- enumerator unknown = 0
enumerator pointer = 0
The device provides absolute screen coordinates.
enumerator keyboard = 1
The device has an interface for providing text input.
enumerator tracker = 2
The device has a motion tracker, such as an HMD.
enumerator vibration = 3
The device can produce force feedback.
enumerator battery = 4
The device provides information about battery life.
- enumerator pointer = 0
- property _battery_data BatteryData
getter for InputDevice::BatteryData InputDevice::_battery_data;
getter for InputDevice::Buttons InputDevice::_buttons;
- property axes Sequence[AxisState]
Returns the axis state that is set at the given index, or throw an assert if the index was not found in the list.
- property battery BatteryData
Returns a rough indication of the battery level, ranging from 0 (completely empty battery) to the indicated max_level value.
Make device buttons and axes iterable
ButtonStatethat is set at the given index, or throw an assert if the index was not found in the list.
- property connected bool
This is false if we know that the device is not currently connected. May report false positives if we can’t know this with certainty.
Returns true if the device is still connected and able to receive data, false otherwise. May return false positives.
- property device_class DeviceClass
This contains an identification of the general type of device. If this could not be determined, it is set to DC_unknown.
Returns an identification of the general type of device. If this could not be determined, returns DeviceClass.unknown.
Disables the generation of mouse-movement events.
Enables the generation of mouse-movement events.
- findAxis(axis: Axis) AxisState
Returns the first AnalogAxis found with the given axis, or throw an assert if the axis was not found in the list.
- findButton(handle: ButtonHandle) ButtonState
Returns the first
ButtonStatefound with the given axis, or throw an assert if the button handle was not found in the list.
- getButtonEvents() ButtonEventList
Returns the list of recently-generated
ButtonEvents. The list is also cleared.
- getPointerEvents() PointerEventList
PointerEventListcontaining all the recent pointer events. Clears the list.
- hasButtonEvent() bool
Returns true if this device has a pending button event (a mouse button or keyboard button down/up), false otherwise. If this returns true, the particular event may be extracted via get_button_event().
- hasPointerEvent() bool
Returns true if this device has a pending pointer event (a mouse movement), or false otherwise. If this returns true, the particular event may be extracted via get_pointer_event().
- property manufacturer string
The device’s manufacturer, or the empty string if not known.
Returns a string containing the manufacturer of the device, if this information is known.
- mapAxis(index: int, axis: Axis)
Associates the indicated Axis with the axis of the indicated index number. Pass Axis::none to turn off any association.
It is not necessary to call this if you simply want to query the state of the various axes by index number.
- mapButton(index: int, handle: ButtonHandle)
Associates the indicated
ButtonHandlewith the button of the indicated index number. When the given button index changes state, a corresponding
ButtonEventwill be generated with the given
ButtonHandle.none()to turn off any association.
It is not necessary to call this if you simply want to query the state of the various buttons by index number; this is only necessary in order to generate
ButtonEventswhen the buttons change state.
- property name string
The human-readable name of this input device.
Returns a human-readable name for the device. Not necessarily unique.
Polls the input device for new activity, to ensure it contains the latest events. This will only have any effect for some types of input devices; others may be updated automatically, and this method will be a no-op.
- property product_id int
USB product ID of the device, or 0 if not known.
Returns a string containing the USB product ID of the device, if this information is known.
- property serial_number string
The device’s serial number, or the empty string if not known.
Returns a string containing the serial number of the device, if this information is known.
- setVibration(strong: float, weak: float)
Sets the strength of the vibration effect, if supported. The values are clamped to 0-1 range. The first value axes the low-frequency rumble motor, whereas the second axes the high-frequency motor, if present.
- property tracker TrackerData
Getters for the various types of device data.
TrackerDataassociated with the input device’s tracker. This only makes sense if
hasTracker()also returns true.
