Enhancing Your Godot 4 Game: Implementing a Point-and-Click System

In this tutorial, we will delve into creating a point-and-click system inside Godot 4. Although I covered this previously, recent changes by the Godot developers necessitate a revamped approach. So, let's explore how to develop a functional point-and-click mechanism.

Setting Up the Scene

To initiate the process, we need to establish the foundation of our point-to-move system within the scene:

  1. Creating the Navigation Setup:

    • Begin by adding a Navigation Region 3D node to leverage Godot's built-in navigation system.
    • Generate a navigation mesh by adding a Mesh Instance 3D node with a Box Mesh to facilitate movement.

  2. Implementing Collisions:

    • Enhance the mesh by including a Static Body 3D node with a Collision Shape 3D, ensuring collision detection for objects.

  3. Configuring the Camera:

    • Attach a Camera 3D node to enable visibility within the scene and adjust its position accordingly.

Implementing the Click-to-Move Functionality

Handling Input Events

  • Utilize the input function to detect mouse clicks for initiating movement.
  • Set up the left mouse button action using the Input Map settings for seamless interaction.

Establishing Raycasting

  • Conduct raycasting from the camera to the ground for accurate positioning.
  • Define the ray length and calculate the ray's trajectory based on the mouse position and camera setup.

Interpreting Results and Setting Target Locations

  • Process the raycast results to obtain the target position for movement.
  • Direct the navigation agent to the target location using set_target_location.

Implementing Character Movement

  • Develop a function, move_to_point, to handle character movement towards the target location.
  • Calculate the direction and velocity to facilitate smooth navigation towards the designated point.

Refining Movement and Orientation

Ensuring Proper Navigation

  • Adjust path_desired_distance and target_desired_distance parameters to fine-tune navigation accuracy.

Managing Character Orientation

  • Create a move_towards_direction function to make the character face the target direction accurately.
  • Implement proper orientation adjustments based on the calculated direction vector.

Conclusion

Mastering the art of implementing a point-and-click system in Godot 4 enriches your game development prowess. By comprehensively understanding the intricacies of navigation, raycasting, and character movement, you can elevate user experience and gameplay dynamics. Stay tuned for more exciting tutorials and updates on game development techniques.

Remember, practice makes perfect, and experimentation is key to honing your skills in game development!
