Inherits:: Item
Detailed Description▲
This helper provides a way to rotate a camera around an origin. To function OrbitCameraController accepts a Node as the origin, and a Camera object which should be a child of the originNode to control. By only adjusting the z position of the child camera relative to the parent origin it has the effect of moving the camera nearer or farther from the target origin. By applying a rotation to the origin node, the child camera will be orbited around the origin node.
The OrbitCameraController item itself is a 2D item that accepts input events so whatever it's size and position will be where input events are accepted. To zoom either use the scroll wheel of the mouse or perform a pinch gesture. To rotate click or touch and drag the area. To pan, hold control and drag the area. Panning will change the position of the origin node. It is also possible to perform a panning gesture by performing a two finger drag.
