It looks like your message is incomplete. Could you please clarify what you would like me to calculate? For example, do you want a calculation related to the Fortnite-like project (e.g., physics, damage, movement speed), or is it a general calculation? Please provide more details so I can help you!

To move and look around in the Fortnite-like scene:

1. Click anywhere on the canvas (the 3D scene) to enable pointer lock.

   • This will hide your mouse cursor and allow you to look around with your mouse.

2. Use the keyboard to move:

   • W: Move forward
   • A: Move left
   • S: Move backward
   • D: Move right
   • Space: Jump
   • Shift: Sprint

3. Move your mouse to look around (after pointer lock is enabled).

4. Click to shoot.

5. Press the UI buttons for emotes or to build a wall.

If you ever lose pointer lock (for example, by pressing Esc), just click the scene again to regain control.

If you still can't move:

• Make sure you click the 3D scene area first to enable pointer lock.
• Movement and mouse look only work when pointer lock is active.

Let me know if you want to add more features or need further help!
