Our Developments in This Scene

This project expands the 3-e complete building scene by adding a new bedroom and custom features:

1. Added a Bedroom

• 🛏️ Built a bedroom in the 3-e complete building scene using ProGrids for precise alignment.
• Included:
  • A bed, custom-built using Unity's ProBuilder tool.
  • A desk and chair, also designed with ProBuilder.
  • A lamp prefab from the Roman Furniture Pack for decoration and lighting.

2. Integrated Prefabs

• 🪑 Used prefabs from the Roman Furniture Pack to enhance the room's appearance and add functional elements.

3. Added a Corridor

• 🚪 Constructed a corridor to connect the new bedroom to the main building.

4. Improved Lighting

• 💡 Added Point Lights to illuminate the room effectively, including the lamp as a light source.

5. New Player Interactions

• 🏃‍♂️ Jumping Ability: The player can now jump using the spacebar. script reference:

  07-unity-3d-terrain-ai/Assets/Scripts/1-player/CharacterKeyboardMover.cs

  Lines 73 to 79 in 3ee98bd

  	// Handle jump
  	if (jumpAction.WasPressedThisFrame())
  	{
  	velocity.y = jumpSpeed; // Apply vertical jump velocity
  	velocity.x *= slowDownAtJump;
  	velocity.z *= slowDownAtJump;
  	}

• 👀 Interactive Objects: When the player is near another capsule GameObject, a message will appear when the E key is pressed. script reference:

  07-unity-3d-terrain-ai/Assets/Scripts/3-objects/popMessageAction.cs

  Lines 31 to 37 in b44bf5b

  	public void EnableDisableActionFunc(bool isActionEnabled)
  	{
  	text.enabled = isActionEnabled;
  	textBackground.gameObject.SetActive(isActionEnabled); // Hide by default
  	text.text = textContent;
  	}
  	}

• 💡 Light Control: The player can turn the bedroom light on and off by pressing the L key. If the player is too far from the light, it will automatically turn off after a certain radius. script reference:

  07-unity-3d-terrain-ai/Assets/Scripts/3-objects/LightAction.cs

  Lines 21 to 26 in b44bf5b

  	public void EnableDisableActionFunc(bool isActionEnabled)
  	{
  	lightSource.enabled = isActionEnabled;
  	Debug.Log("is light: " + lightSource.enabled.ToString());
  	}
  	}
