Examples

The following paragraphs contain Path Creator used in a practical example. Create a path creator behaviour at runtime and add custom path nodes.

using UnityEngine;
using MDPackage.Geometry;

public class SampleScript : MonoBehaviour
{
private MDG_PathCreator pathCreator;
private Vector3 currentNodePos;

private void Start()
{
// Create a new path creator on startup
pathCreator = gameObject.AddComponent<MDG_PathCreator>();
pathCreator.transform.position = Vector3.zero;
}

private void Update()
{
// Create path nodes on the specific direction
// use WASD to add path nodes
if (Input.GetKeyDown(KeyCode.W))
AddNode(Vector3.forward);
if (Input.GetKeyDown(KeyCode.D))
AddNode(Vector3.right);
if (Input.GetKeyDown(KeyCode.S))
AddNode(Vector3.back);
if (Input.GetKeyDown(KeyCode.A))
AddNode(Vector3.left);

// Local method
void AddNode(Vector3 pos)
{
currentNodePos += pos;
pathCreator.Path_AddNode(currentNodePos);
}
}
}
