C# Class Nez.FollowCamera

basic follow camera. LockOn mode uses no deadzone and just centers the camera on the target. CameraWindow mode wraps a deadzone around the target allowing it to move within the deadzone without moving the camera.

Property Details

camera public_oe property

public Camera,Nez camera
return Camera

deadzone public_oe property

when in CameraWindow mode the width/height is used as a bounding box to allow movement within it without moving the camera. when in LockOn mode only the deadzone x/y values are used. This is set to sensible defaults when you call follow but you are free to override it to get a custom deadzone directly or via the helper setCenteredDeadzone.
public RectangleF deadzone
return RectangleF

focusOffset public_oe property

offset from the screen center that the camera will focus on
public Vector2 focusOffset
return Vector2

followLerp public_oe property

how fast the camera closes the distance to the target position
public float followLerp
return float

mapLockEnabled public_oe property

If true, the camera position will not got out of the map rectangle (0,0, mapwidth, mapheight)
public bool mapLockEnabled
return bool

mapSize public_oe property

Contains the width and height of the current map.
public Vector2 mapSize
return Vector2
