If your character or screen is “turning sideways” in Terra (or any Roblox game), the fix depends on whether you mean camera/screen rotation or character movement/rotation. Here’s how to solve both, based on common Roblox issues discussed in forums and tutorials.

1. Fixing Screen/Camera Rotation (Mobile)

If your phone screen won’t rotate sideways while playing Terra on mobile:

Quick Fixes:

  • Turn off Rotation Lock
    • Swipe down from the top (Android) or swipe from the top-right (iPhone) to open quick settings.
    • Tap to disable Rotation Lock or enable Auto-Rotate.
  • Restart the Game
    • Close Roblox completely and reopen it.
  • Update Roblox
    • Check your app store for updates; outdated versions sometimes break rotation.
  • Reinstall Roblox
    • As a last resort, offload/uninstall and reinstall the app.

“If this option [auto-rotate] is not enabled, then you can just simply launch the game and then just tilt your phone a bit… it should turn sideways.”

2. Fixing Character Turning/Walking Sideways (PC or Mobile)

If your avatar is rotating unexpectedly or “walking sideways” instead of forward:

Enable Shift Lock (PC)

  • Press Esc → enable Shift Lock Switch.
  • Press Left Shift in-game to lock your camera.
  • Now your character moves in the direction you press (WASD) without spinning.

Disable AutoRotate (Developers or Custom Characters)

If you’re dealing with a custom avatar or creating a game:

  • Set Humanoid.AutoRotate = false in scripts to stop automatic turning.
  • For custom models, ensure the PrimaryPart (like HumanoidRootPart) faces the correct direction.

3. If You’re a Developer (Terra Game Creators)

If you’re building or scripting Terra and players report sideways turning:

  • Unbind movement actions using ContextActionService:UnbindAction() if needed.
  • Check your camera scripts and ensure they’re not forcing unwanted rotation.
  • Use Humanoid.AutoRotate = false to give players manual control.

TL;DR

  • Screen won’t rotate? → Disable rotation lock, update/restart Roblox.
  • Character spins/walks sideways? → Use Shift Lock (PC) or disable AutoRotate (scripting).
  • Developer? → Check camera scripts, movement bindings, and model orientation.
