GameInputForceFeedbackEnvelope (v2)

Defines an envelope that modifies a force-feedback effect.

Syntax

struct GameInputForceFeedbackEnvelope
{
    uint64_t attackDuration;
    uint64_t sustainDuration;
    uint64_t releaseDuration;
    float    attackGain;
    float    sustainGain;
    float    releaseGain;
    uint32_t playCount;
    uint64_t repeatDelay;
};

Members

attackDuration Type: uint64_t

Time in microseconds to reach the sustain level of a force-feedback effect envelope.

sustainDuration Type: uint64_t

Time in microseconds from the start of the sustain duration until the release component of a force-feedback effect envelope. If the effect is intended to run forever, use UINT64_MAX for the this value.

releaseDuration Type: uint64_t

Time in microseconds from the sustain duration to the release of a force-feedback effect envelope.

attackGain Type: float

Modifier on the attack of force-feedback effect envelope.

sustainGain Type: float

Modifier on the sustain gain of a force-feedback effect envelope.

releaseGain Type: float

Modifier on the release gain of a force-feedback effect envelope.

playCount Type: uint32_t

Number of iterations that the envelope will be applied to the force-feedback event.

repeatDelay Type: uint64_t

Interval of time between applications of the force-feedback envelope.

Remarks

GameInputForceFeedbackEnvelope is a member of the GameInputForceFeedbackConstantParams, GameInputForceFeedbackPeriodicParams, and GameInputForceFeedbackRampParams structures. Force-feedback envelopes are modifiers on force feedback effects that modify their output through the device. For more information, see Advanced GameInput topics.
