Visualize a trajectory of a drone flight?


I am currently working on a real life drone project. As an example of a drone flight I am doing a visualization in Unity. What I want to do is to have a trajectory defined in an array (my guess is using Vector3), read the coordinates from the array and send the drone object to fly a certain path and follow the points from the trajectory array.

I am very new to the Unity environment and would be happy if you could give me some tips on how and where to start.


you can probably use a camera cutszene script from the workshop and jsut use the drone model instead of the camera

There are a few ways to do this. Here’s one way, using a coroutine.
They can be seen as separate threads (although they are not, in most cases they behave like one).

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TestScript : MonoBehaviour {

	public List<Vector3> positions;     //Your positions, set ininspector;
	public float speed;                 //Set in inspector to change speed.

	public Transform drone; //The object you want to move

	void Start () {

	private IEnumerator MoveAlongPath(){

		int index = 0;
		Vector3 currentGoal = positions[index];
		drone.transform.position = currentGoal; //Set drone to start position.

        while (index < positions.Count)
			currentGoal = positions[index];
			while(drone.transform.position != currentGoal){
				drone.transform.position = Vector3.MoveTowards(drone.transform.position, currentGoal, Time.deltaTime * speed);
				drone.LookAt(currentGoal); //make drone face towards goal.
				yield return null; //Wait for next frame.

And here’s a image showing how this would be used in the inspector:

Thank you so much, that is exactly what I need!
