Module 4: Camera Manipulations and Multiple Views¶

Basic Camera Controls¶

Run Behavior¶

Text Only
N: Move camera by (x, y) values (from X/Y slider bars)
M: Move camera to (x, y) values (to Dye's location)
H: Zoom with respect to center (zoom factor slider)
J: Zoom with respect to Dye (zoom factor slider)

Scene Setup¶

Text Only
MainCamera:
    - Has CameraSupport

UI-Canvas:
    - X/Y/Zoom sliders (connected to UserControlLogic)

TheWorld:
    - Has UserControlLogic
    - Background: Z=1 (larger than hero and egg)
    - Hero and Egg components

Core Components¶

UserControlLogic - Central object for receiving/parsing user input - Connects to UI sliders and game objects - Transmits input to cause changes

Camera Support - CameraSupport: includes ClampToWorldBound() - CameraSupport_Manipulate: handles camera operations - MoveBy - MoveTo - Zoom (towards center) - ZoomTowards (point) - PushCameraByPos()

Lerp Implementation¶

Run Behavior¶

Text Only
Z: Trigger Lerp effect
    - Increases to double size
    - Gradually lerps back
    - Can compound if triggered repeatedly

TimedLerp Class¶

Text Only
- Performs lerp over fixed duration
- Rate measured in seconds
- Rate and Duration controlled via UI sliders

HeroControl Integration¶

Text Only
- BeginLerp() initiates lerp
- LerpIsActive() monitors lerp status
- SetLerpParms() optional for known values

Camera Manipulation¶

Enhanced Features¶

Text Only
- Position Lerp
- Size Lerp
- Automatic Update() checking
- Damping effects on movement

Shake Implementation¶

Text Only
- X key triggers camera shake
- Uses DampedHarmonic function
- Configurable cycles and duration
- Returns to original position after shake

Viewport and Hero Cam¶

Small Camera Setup¶

Text Only
- Projection: Orthographic
- Depth: > 0 (Main Camera at -1)
- Configurable viewport settings

CameraSupport Functions¶

Text Only
- SetViewportMinPos(x, y)
- SetViewportSize(w, h)
- Viewport manipulation controls

Scene Management¶

Scene Transition¶

Text Only
- L key loads new scene
- Maintains lerp and shake information
- Uses UnityEngine.SceneManagement

Persistence¶

Text Only
- GameState class implements Singleton Pattern
- DontDestroyOnLoad() functionality
- Level-specific organization in folders

Project Organization¶

Text Only
- Level-Specific folders
- Utility folder for camera components
- Separated level behaviors
- Centralized game management
