Member Function Documentation

◆ HandleEvents()

bool AzFramework::PanCameraInput::HandleEvents ( const InputState &  state,
const ScreenVector &  cursorDelta,
float  scrollDelta 
)
overridevirtual

Respond to input events to transition a camera input to active, handle input while running, and restore to idle when input ends.

Implements AzFramework::CameraInput.

◆ StepCamera()

Camera AzFramework::PanCameraInput::StepCamera ( const Camera &  targetCamera,
const ScreenVector &  cursorDelta,
float  scrollDelta,
float  deltaTime 
)
overridevirtual

Use processed input events to update the state of the camera.

Note
targetCamera is the current target camera at the beginning of an update. The returned camera is the targetCamera + some delta to get to the next camera position and/or orientation.

Implements AzFramework::CameraInput.
