# Fly Camera Addon for Godot 4
A camera addon for flying around scenes at runtime, which can be handy during the prototyping phase of a project, for example.
The camera is easy to use. You can just drop it in a scene, and run the game.
Optionally you can also tweek the camera node settings in the inspector (speed, mouse sensitivity, etc).
By default the camera uses `WASD` keys for movement, `Shift` to move faster, `Ctrl` to move slower,
and `Right Mouse Button` to activate/deactivate the camera's mouse controls.
Please refer to the documentation for more information.

extends CharacterBody3D
##
## A free flying camera, handy for prototyping.
## [br][br]
##
##
## This camera allows to quickly be able to fly around at runtime.
## Just put it in a scene and it should be good to go. You can optionally
## tweak its settings in the inspector.
## [br][br]
##
## The camera node itself is not an actual camera, but a [CharacterBody3D], so
## it has no visual preview in the inspector. You can still align it to the
## camera in the 3D View, by clicking [param Perspective > Align Transform With View].
## [br][br]
##
## You will also see a warning in the [param Scene] tree about the [CharacterBody3D]
## not having a shape. Normally a flying camera doesn't need any collisions,
## and you can ignore the warning. The camera still supports collisions, though,
## either by turning on [param Use Collisions] in the inspector, or by
## manually adding a [CollisionShape3D] node with a shape of your choice.
## [br][br]
##[color=white][b]Note:[/b][/color] the collisions are added at runtime, so
## turning on [param Use Collisions] will not suppress the warning.
## [br][br]
##
## The camera controls can be changed. By default it uses the [param WASD]
## keys for movement, [param Shift] to move faster, [param Ctrl] to move slower, and
## the [param Right Mouse Button] to activate/deactivate the mouse controls
## (capturing/uncapturing the mouse pointer).
## [br][br]
##
## This camera was intended for quick use, so the default controls are easy to
## change in the camera script by hand (in the [param _actions_to_key] dictionary).
## However, if you prefer, you can also set the following input actions in
## your project settings, and the camera will automatically use them instead:
## [codeblock]
##cam_forward
##cam_backward
##cam_left
##cam_right
##cam_faster
##cam_slower
##cam_activate
## [/codeblock]
## [color=white][b]Note:[/b][/color] the mouse button used to activate the
## camera can easily be changed in the inspector, so for that end you don't
## need to use [param cam_activate] input action.
## This action is provided in case you'd like to use a keyboard key instead.
##
##
## How to activate mouse controls.
enum ActivationMode {
ON_CLICK, ## Click to activate, click again to deactivate.
ON_HOLD, ## Hold mouse button to activate, release to deactivate.
}
## Where to revert the mouse pointer when releasing mouse controls.

CLICK_POSITION, ## The position where the mouse was initially clicked.
