Control node position and orientation with keys and mouse. 更多...
import 语句: | import QtQuick3D.Helpers |

This helper allows the user to control a node using W, A, S, D, the arrow keys, and the mouse. Usually the controlled node is a Camera, specified in the controlledObject 特性。
Adding a WasdController can be highly useful both in applications that wish to provide a standard way of navigating the scene, and also as a temporary measure during development and troubleshooting, as it allows inspecting the scene at run time via familiar keyboard and mouse navigation.
The key bindings are as follows:
W
or
up
- go forward
S
or
down
- go backward
A
or
left
- strafe left
D
or
right
- strafe right
R
or
page up
- move up
F
or
page down
- move down
shift
together with other keys - move faster, depending on
shiftSpeed
The following snippet shows how a WasdController object can be added. By default both key and mouse based navigation is active, so in most cases there is no further configuration needed:
View3D { anchors.fill: parent camera: camera PerspectiveCamera { id: camera position: Qt.vector3d(0, 0, 600) } ... } WasdController { controlledObject: camera }
