This script "plug and play", read setup section for detailed information. Since it's my first time making anything in any kind on game engine, if you have any suggestions here is my twitter. Feel free to use or contribute to the code any how you want, just add my attribution and the LICENSE file to your project that's it.
Present Features
- Movement with 'W','A','S','D'.
- Movement with cursor when at the edge of the screen, like some RTS games.
- Panning left and right with 'Q' and 'E'.
- Tilting up and down with 'R' and 'F'.
- Zoom in and out with scroll wheel.
- Point and look while pressing middle mouse and dragging.
- Majority of the variables are exported to make tweaking, on the go, easy.
Demo
The DEMO.mp4 video in the root folder shows the working of this script, there is also a Example.tscn in the Example folder, to try it out for your self before getting deep into it.
To-do/Upcoming features
- Add diagonal movement.
- Add follow camera.
- Add de-accelaration to tilting in tilt_node.
- Make zooming smooth
- Configurable Keys
- Jump to location
- Reset to normal orientation
- (Optional) Picture in picture
Setup
Simply add the Camera.tscn form the Example folder to your scene tree and it will work fine.
Note: If you want to change the default camera angle(looking down, left or right), do that changes to the camera node in Camera.tscn before adding it to any scene or project
This is how the Camera.tscn is setup, it's for reference to the contributors.
- 'move_node' and 'tilt_node' are Spatial nodes.
- 'camera' is a Camera node.

- acc - acceleration of the camera while moving over the scene.
- dec - de-acceleration of the camera while moving over the scene.
- MAX_SPEED - maximum speed the camera can attain while moving.
- ang_acc - acceleration of camera while panning left or right.
- ang_dec - de-acceleration of the camera while panning left or right.
- MAX_ANG_SPEED - maximum speed the camera can attain while panning left or right.
- MOUSE_SENSITIVITY - sensitivity of the mouse while pressing the middle mouse button and dragging the camera horizontally.
tilt_node
It is responsible for tilting the camera up or down.
- ang_acc - acceleration of camera while tilting up or down.
- MAX_ANG_SPEED - maximum speed the camera can attain while tilting up or down.
- low - how low the camera can go while tilting(in terms of radian).
- high - how high the camera can go while tilting(in terms of radian).
- MOUSE_SENSITIVITY - sensitivity of the mouse while pressing the middle mouse button and dragging the camera vertically.
