Creating Path Movement in Godot: A Step-by-Step Guide

In this tutorial, we will explore how to utilize nodes in Godot to make a character patrol or move along a predefined curve. This video guide will walk you through creating a path, drawing a curve, and leveraging a simple property of a node to facilitate character movement along the defined route.

Creating the Path

To start, hide the character and select the root node of the scene. Add a new Path3D node for 3D scenes (or the 2D equivalent), which will unveil new options in the toolbar. Click on the green icon to add points to your curve by clicking in the viewport. To ensure accuracy, switch to a top-down view by pressing '7' on your keypad. Create points in a top-down view to form the desired path, enabling you to manipulate the perspective effectively.

Enhancing the Path

To create smooth curves, select the leftmost tool, press shift, and click and drag on any point to drag out handles. These handles will help in smoothing out the path, akin to using Bezier curves in a vector drawing program.

Moving Objects Along the Path

After creating the path, the next step involves moving an object along it. This can be achieved by adding a child node called PathFollow3D to the path node. Adjusting the progress properties in the inspector will move the object along the path, with the option to place any entity as a child of the PathFollow3D node.

Scripting Movement

For dynamic movement control using code, a script can be created. By incrementing the PathFollow3D's progress value in the physics_process function, you can achieve continuous movement along the path. This method allows for flexibility in altering the position on the path through code.
