triggered()

Detailed Description

Actions can be boolean, such as a button press, or analog, such as a joystick axis.

Use the pressed property or the triggered signal to react to a boolean action. An analog action will set the value property.

Note: For convenience, an analog property will also set the pressed property and emit the triggered signal, while a boolean property will set value to 1.0 when pressed.

The following shows how to react to either the right hand grip being pressed or to a right hand pinch gesture from hand tracking:

XrInputAction {
    hand: XrInputAction.RightHand
    actionId: [XrInputAction.SqueezePressed, XrInputAction.SqueezeValue, XrInputAction.IndexFingerPinch]
    onTriggered: console.log("Do action here.")
}

The reason for specifying both SqueezePressed and SqueezeValue is that some controllers have an analog grip button, and some controllers just have an on/off grip switch.

actionName : string

The name of the input action.

Use this property to specify the name of the custom input action you want to react to. This property does not have an effect if actionId is set.

hand : enumeration

The Hand that this input action will apply to.

Specifies the hand ro react to.

It can be one of:

Constant	Value
`XrInputAction.LeftHand`
`XrInputAction.RightHand`
`XrInputAction.Unknown`

pressed : bool

Indicates whether the input action is currently pressed.

Use this property to check if the input action (for example, a button) is currently pressed.

value : real

The analog value of the input action.

For analog inputs, such as a thumbstick position, this property holds the value of the input (usually in the range [0, 1]).

Signal Documentation

triggered()

This signal is emitted when a boolean action is activated. This happens at the same time as the pressed property is set to true.

Note: The corresponding handler is onTriggered.
