C Specification

The XrActionStateBoolean structure is defined as:

typedef struct XrActionStateBoolean {
    XrStructureType       type;
    void* XR_MAY_ALIAS    next;
    XrBool32              currentState;
    XrBool32              changedSinceLastSync;
    XrTime                lastChangeTime;
    XrBool32              isActive;
} XrActionStateBoolean;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to an extension-specific structure.

  • currentState is the current state of the action.

  • changedSinceLastSync is XR_TRUE if the value of currentState is different than it was before the most recent call to xrSyncActionData. This parameter can be combined with currentState to detect rising and falling edges since the previous call to xrSyncActionData. E.g. if both changedSinceLastSync and currentState are true then a rising edge (XR_FALSE to XR_TRUE) has taken place.

  • lastChangeTime is the XrTime in nanoseconds since this action’s value last changed.

  • isActive is XR_TRUE if and only if there exists an input source that is contributing to the current state of this action.

Description

See XrActionCreateInfo for a description of subaction paths, and the restrictions on their use.

Valid Usage (Implicit)

  • type must be XR_TYPE_ACTION_STATE_BOOLEAN

  • next must be NULL
