Camera

Each room has a camera, set up in the room Inspector. In the code, it is in scene().camera.

Properties

Property	Type	What it is
x, y	float	Top left corner of the area shown, in world coordinates.
zoom	float	How much the world is magnified (1 = no zoom). The interface and onRenderGui are not magnified, and mouseX()/mouseY() are already in world coordinates.
bounded	bool	true = while following a target, the camera doesn’t leave the room. Moved by hand, it isn’t limited.
smoothing	float	From 0 to 10. 0 sticks to the target; 10 is very smooth.
deadzoneW, deadzoneH	float	Size of the central rectangle in which the target moves without moving the camera.

Functions

Function	What it does	Example
void follow(Handle<Entity> target)	Starts following an instance. The camera centers on it already on the first frame.	scene().camera.follow(handle());
void stopFollowing()	Stops following; the camera stays where it is.	scene().camera.stopFollowing();
void shake(float strength, float seconds)	Shakes the screen for seconds seconds, up to strength pixels to each side, weakening until it stops.	scene().camera.shake(3, 0.2f);

Example

void onSpawn() override {
    scene().camera.follow(handle());  // follow this instance
    scene().camera.smoothing = 4;
    scene().camera.bounded = true;
}

handle() returns a safe reference to this instance: see Handles.
