  1. Okay, I need to create a single-page HTML game using Babylon.js where the player controls a ship exploring islands to find treasure. Let me break this down step by step.
  2.  
  3. First, I'll set up the basic HTML structure. The user wants a single HTML page, so I'll include the Babylon.js CDN link. I'll need a canvas element for the 3D rendering. Also, some UI elements like a score and instructions would be good, so I'll add a div for that.
  4.  
  5. Next, the Babylon.js scene setup. I'll create a createScene function that initializes the engine, canvas, and camera. The camera should be positioned so the player can see the sea and islands. Maybe a fixed camera at a certain height and looking down.
  6.  
  7. Then, the ship. The ship needs to be a 3D model that the player can move. Since the user didn't specify models, I'll use simple shapes for now. Maybe a box for the ship. I'll add a mesh for the ship and position it at the starting point, like (0, 0.5, 0) to be above the sea level (assuming the sea is at y=0).
  8.  
  9. Movement controls. The player should use arrow keys or WASD. I'll handle the input events, like onkeydown. For movement, I'll adjust the ship's position based on the keys pressed. Maybe add some speed variables for x and y directions. Also, need to prevent the ship from moving through islands, so collision detection might be necessary. But since the map is small, maybe just check the ship's position against the islands' positions. Hmm, but that could be complex. Maybe for simplicity, just let the ship move freely, but in a real game, collision detection would be important.
  10.  
  11. Islands and treasure. The user wants 3 islands, one with treasure. I'll create three island meshes. Each island can be a simple cylinder or box. Position them at different coordinates. Let's say island1 at (10, 0, 0), island2 at (-5, 0, 5), and island3 at (5, 0, -3). Only one of them has the treasure. I'll randomly assign the treasure to one island. Then, create a treasure mesh (maybe a sphere) on that island. When the ship comes close to the treasure, trigger a win condition.
  12.  
  13. Treasure detection. How to check if the ship is near the treasure? Maybe calculate the distance between the ship's position and the treasure's position. If it's below a certain threshold, like 2 units, then the player wins. So in the game loop, after updating the ship's position, check the distance to the treasure. If close enough, display a win message and stop the game.
  14.  
  15. UI elements. The score can start at 0 and increase when the player finds the treasure. Or maybe the score is just a counter for points, but in this case, finding the treasure ends the game. So the UI will show the current score and instructions. I'll use a div with some CSS styling to position it at the top of the screen.
  16.  
  17. Putting it all together. The createGame function will initialize the scene, add the ship, islands, treasure, and set up event listeners for input. The render loop will update the ship's position and check for treasure proximity.
  18.  
  19. Testing. I'll need to make sure the ship moves correctly, the islands are placed, and the treasure is detected. Also, check that the UI updates properly when the game is won.
  20.  
  21. Potential issues: Camera position might need adjustment to view the ship and islands properly. The ship's movement speed might be too fast or slow. Collision detection is minimal here, but since the user didn't specify, maybe it's okay. The treasure detection distance needs to be set correctly so the player can get close enough.
  22.  
  23. I think that's the plan. Now, code it step by step, making sure each part works before moving on. Start with the scene setup, then add the ship, then islands, then treasure, then movement and detection.
  24.

  26. Here's a simple Babylon.js game where you control a ship to find treasure on one of three islands:

  183. - Game ends when treasure is found
  184. - Simple boundary detection to keep ship within play area
  185.  
  186. To play:
  187. 1. Use WASD to move the ship

  189. 3. Find the golden treasure sphere on one of the islands
  190. 4. When you find the treasure, your score will update and the game will end
  191.  
  192. The game uses basic 3D shapes for simplicity. You can enhance it by:
  193. - Adding more detailed models
  194. - Implementing proper collision detection
  195. - Adding animations
  196. - Including sound effects
  197. - Creating a more complex map
  198. - Adding multiple treasures or challenges
