6 Resource Integration

The integration of resources is a crucial aspect in video game development, as it includes the incorporation and management of all the visual and auditory elements that make up the game. This section covers importing and managing assets, implementing sound effects and music, and creating and using animations.

6.1 Import and Asset Management

• 3D Models & Sprites

3D models:

• Importing 3D Models:
  • Example in Unity:
    1. Drag and drop the model file (for example, fbx, .obj) into the Assets folder.
    2. Select the model in the Project panel.
    3. Configure import properties, such as scaling and animation, in the Inspector.
• 3D Model Management:
  • Organize models into folders within Assets to keep your project structured.
  • Use prefabs to create reusable instances of models configured with additional components.

Sprites:

• Importing Sprites:
  • Example in Unity:
    1. Drag and drop the image file (for example, .png, .jpg) into the Assets folder.
    2. Select the image in the Project panel.
    3. Configure import properties, such as sprite type (Single or Multiple) and compression format, in the Inspector.
• Sprite Management:
  • Organize sprites into folders within Assets.
  • Use Sprite Atlas to group multiple sprites into a single texture, improving performance.

6.1.2 Textures and Materials

Textures:

• Importing Textures:
  • Like sprites, drag and drop texture files into the Assets folder.
  • Configure import properties, such as compression format and mipmap, in the Inspector.

Materials:

• Creation and Management of Materials:
  • Example in Unity:
    1. Create a new material in Assets > Create > Material.
    2. Assign a texture to the material by dragging the texture from the Project panel to  the Albedo  field in the Material Inspector.
    3. Adjust material properties such as color, shader, and physical properties (metallic, smoothness).

6.2 Implementing Sound Effects and Music

Audio Import:

• Example in Unity:
  1. Drag and drop audio files (for example, .wav, .mp3) into the Assets folder.
  2. Configure audio import properties, such as compression format and in-memory load, in the Inspector.

Audio Playback:

• Use of Audio Source:

Example in Unity:

Set the AudioSource in the Inspector, assigning the audio clip and adjusting properties such as volume, pitch, and loop.

6.3 Animations

6.3.1 Creating and Using Animations

Creating Animations:

• Example in Unity:
  1. Open the Animation window (Window > Animation > Animation).
  2. Select the object you want to add an animation to.
  3. Create a new animation clip and add keyframes for animable properties (position, rotation, scale, etc.).

Use of Animations:

• Animation Control:Set up the Animator in the Inspector, assigning the animation handles and setting the parameters (triggers, bools, floats).

Example in Unity:

6.3.2 Animation Systems and Blend Trees

Animation Systems:

• Animator Controller:
  • Create an Animator Controller in Unity.
  • Configure the animation states and transitions between them in the Animator window.

Blend Trees:

• Creation of Blend Trees:
  • Example in Unity:
    1. Open the Animator window.
    2. Create a new Blend Tree within the Animator Controller.
    3. Add parameters and animations to the Blend Tree to mix multiple animations based on parameter values.
    4. Set up the Blend Tree to mix walking and running animations based on the character’s speed.
• Using Blend Trees:
  • Example of Blend Tree Setup:
