+# Background
+
+Is the visual scenery that appears behind the gameplay elements.
+
+---
+
+The background consists of 2 parts: **Landscape** and **Portrait**.
+
+- **Landscape** use for Desktop and Mobile landscape.
+- **Portrait** only use for Mobile portrait.
+
+| | Desktop | Mobile |
+|:-:|--------------|---------|
+|**Background Landscape**
|
|
|
+|**Background Portrait**
||
|
+
+### 1. Prepare the assets
+| | Assets | Description |
+|:-:|--------------|---------|
+|**Static**
||Static background is necessary for the game|
+|**Animation**
||Animation background may or may not be present, depending on the game design|
+
+### 2. Setup Background Landscape
+
+ We use sprite frame background for landscape from prepared assets.
+
+ 
+
+### 3. Setup Background Portrait
+
+ We use sprite frame background for mobile from prepared assets.
+
+ 
+
+### 4. Setup Background Animation
+
+If the game have design animation for background, we will do this step.
+
+**Setp 1:** Using hepler to generate animation from prepared assets
+
+ 
+ 
+
+**Setp 2:**. Stup for spine-animation
+ - `Is Loop`: is ✅ because this animation will play through the game.
+ - `Static Sprite Frame`: It will be displayed when the animation has not finished loading.
+
+ 
+ 
+
+**Setp 3:**. Add animation background with components below:
+
+ **Landscape:**
+ - Create `Empty Node` with name `anim-background-main-game`.
+ - Add `animation-play-on-enable` with animation name in **Animation Provider**.
+ - Add `background-scaler`, used to resize according to screen resolution.
+
+ 
+
+ **Portrait:**
+
+ - Create `Empty Node` with name `mobile-background-anim-portrait`.
+ - Add `mobile-portrait-background-ui-controller` to display only on **Mobile**.
+ - Add `orientation-ui-controller` to display on Portrait with the options below.
+
+ 
+
+ - Create `Empty Node` with name `anim-background-main-game`.
+ - Add `animation-play-on-enable` with animation name in **Animation Provider**.
+ - Add `portrait-anim-background-scaler`, used to resize according to screen resolution.
