Camera is a special node that displays what is visible from its current location. Cameras register themselves in the nearest [Viewport] node (when ascending the tree). Only one camera can be active per viewport. If no viewport is available ascending the tree, the Camera will register in the global viewport. In other words, a Camera just provides [i]3D[/i] display capabilities to a [Viewport], and, without one, a scene registered in that [Viewport] (or higher viewports) can't be displayed.
If this is the current Camera, remove it from being current. If [code]enable_next[/code] is [code]true[/code], request to make the next Camera current, if any.
Returns [code]true[/code] if the given position is behind the Camera. Note that a position which returns [code]false[/code] may still be outside the Camera's field of view.
Makes this camera the current Camera for the [Viewport] (see class description). If the Camera Node is outside the scene tree, it will attempt to become current once it's added.
Returns a normal vector from the screen point location directed along the camera. Orthogonal cameras are normalized. Perspective cameras account for perspective, screen width/height, etc.
Returns the 3D point in worldspace that maps to the given 2D coordinate in the [Viewport] rectangle on a plane that is the given distance into the scene away from the camera.
Returns a normal vector in worldspace, that is the result of projecting a point on the [Viewport] rectangle by the camera projection. This is useful for casting rays in the form of (origin, normal) for object intersection or picking.
Returns a 3D position in worldspace, that is the result of projecting a point on the [Viewport] rectangle by the camera projection. This is useful for casting rays in the form of (origin, normal) for object intersection or picking.
Sets the camera projection to orthogonal mode, by specifying a width and the [i]near[/i] and [i]far[/i] clip planes in worldspace units. (As a hint, 2D games often use this projection, with values specified in pixels)
Sets the camera projection to perspective mode, by specifying a [i]FOV[/i] Y angle in degrees (FOV means Field of View), and the [i]near[/i] and [i]far[/i] clip planes in worldspace units.
If not [code]DOPPLER_TRACKING_DISABLED[/code] this Camera will simulate the Doppler effect for objects changed in particular [code]_process[/code] methods. Default value: [code]DOPPLER_TRACKING_DISABLED[/code].
The camera's field of view angle (in degrees). Only applicable in perspective mode. Since [member keep_aspect] locks one axis, [code]fov[/code] sets the other axis' field of view angle.
The camera's projection mode. In [code]PROJECTION_PERSPECTIVE[/code] mode, objects' z-distance from the camera's local space scales their perceived size.
The camera's size measured as 1/2 the width or height. Only applicable in orthogonal mode. Since [member keep_aspect] locks on axis, [code]size[/code] sets the other axis' size length.
Simulate Doppler effect by tracking positions of objects that are changed in [code]_process[/code]. Changes in the relative velocity of this Camera compared to those objects affect how Audio is perceived (changing the Audio's [code]pitch shift[/code]).
