Sure! Here's an example of a simple game utilizing the Three.js library to create a virtual shooting game with a gun. Please note that for simplicity, the game logic and controls are implemented using the mouse instead of smartphone touch controls. You can copy and paste the following code into a single HTML file and open it in a browser to play the game.
Please note that the code expects you to provide a path to your own gun texture image by replacing `'emozi_himawari.png'` with the actual path to your image. Additionally, this code uses the basic mouse movement to control the gun's position. If you want to adapt it for smartphone operations, you would need to modify the controls accordingly using touch events.
