Game Camlock Feature

Create a camlock feature for a game that automatically focuses on the nearest NPC or mob to the player's cursor. The camlock should be toggleable through a mobile-friendly, draggable GUI. 

The camlock must:
- Automatically engage the nearest NPC/mob under the player's cursor.
- Include a toggle in the GUI to enable or disable camlock.
- Provide visual feedback indicating if camlock is active or inactive.

The GUI must:
- Be optimized for mobile devices with touch input.
- Be draggable anywhere on the screen for user convenience.
- Maintain usability across various screen sizes and resolutions.

Optimize the implementation for performance to avoid lag. Provide code snippets or pseudocode demonstrating the camlocking mechanism and GUI interaction logic. Also include a detailed description of the GUI layout, mobile interaction considerations, and any mockups or design asset suggestions needed for implementation.

# Steps
1. Detect nearest NPC or mob to player's cursor.
2. Implement camlock engagement and disengagement logic.
3. Design a draggable toggle button for the camlock GUI.
4. Ensure the GUI works responsively on mobile devices with touch events.
5. Provide clear visual indicators for camlock state.
6. Optimize for cross-device compatibility and performance.

# Output Format
- Code snippets or pseudocode illustrating the camlock detection, toggle, and GUI dragging functionality.
- Description of the GUI structure and mobile interaction design.
- Any visual mockups or conceptual descriptions for GUI appearance.

Ensure the output is clear, practical, and suitable for direct implementation or further development.
