Help Creating a third person platformer like Lucky's Tale

I'm also a huge fan of 3rd person platformers in VR! The other obvious titles for you to play are the Moss games and Ven VR Adventure but Edge of Nowhere and Chronos (old PCVR games) are also well worth a look at.

At the end of the day, game engines are just tools and it's worth you trying both out to see what feels best to you.

Unreal comes with a lot 'out-of-the-box', and if blueprints are your thing you may be find it suits you best. Be warned that it's a complex beast which is arguably better suited to larger teams with multiple specialists with in-depth knowledge of the engine. It's harder to find support and tutorials and it tends to have fewer assets (especially good VR related ones) if you need a helping hand getting started. If you go down that route, https://www.youtube.com/@GDXR is well worth following for tutorials and his VR template.

Unity has fewer bells and whistles but a much larger community and more indie/solo VR developers (which means lots of tutorials, established frameworks, etc.). There are plenty of assets that you'll be able to lean on and I'd argue that it's probably the easiest to get started with even though you will need to get your hands dirty with C# at some point. I don't use visual scripting so have never tried Unity's version (or the third party ones) but there are some.

In general terms, creating a 3rd person perspective in VR, is relatively easy although there are some issues that Lucky's Tale hides due to its great design. The basics is that you would have a normal 3rd person character controller, moved from the player's joystick input. Add a follow script to the player XRRig with the character as the target, but only moving the player's positional transform. Don't force the rotation to look at the character (as you would in a normal non-VR game) as this should always be controlled by the player's actual head movement. You should offset the player so that they're positioned where you want it at a distance above the character. Here's a basic Unity C# script to give you a basic idea:

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

public class CameraFollowVR : MonoBehaviour
{
    private Transform myTransform;
    [SerializeField] private Transform target;
    [SerializeField] private Vector3 offset = new Vector3(0, 0, -5);

    [SerializeField] private float lerpSmooth = 10f;
	
	void Start()
	{
		myTransform = this.transform;
	}
	
	void LateUpdate()
	{
		if (target != null)
		{
			Vector3 destination = new Vector3(target.position.x+offset.x, myTransform.position.y, target.position.z+offset.z);
            myTransform.position = Vector3.Lerp (myTransform.position, destination, Time.deltaTime*lerpSmooth);
			
		}
	}
}

Keep in mind that moving the player in VR can make some people feel nauseous, so keep the character's movement smooth and not too fast. You want linear movement rather than acceleration as again, that can be a trigger for motion sickness. You might notice that offset.y isn't being used, the destination position vector remains at myTransform.position.y. That's because in this simple example I didn't want the camera to move up and down with the character as it jumps. If your level design has some elevation (i.e. you need the character to go up slopes but also jumps) you'll most likely want to code for that. For example, make the destination Vector3 track the character's y position, but only when the CharacterController is not jumping. This is what I mean by Lucky's Tale camera controller making this seem effortless. There's a great attention to detail that makes movement feel very comfortable. In VR development, the devil's in these kinds of  details but please don't let it put you off. Prototype and try it out in the headset, you'll be able to get very far very quickly and trying it out for yourself (and getting other people to try it too) will let you know what tweaks you need to make. Prototype and iterate. Try it in the headset regularly, not just the editor. You won't know if it works until you're actually in VR.

Have fun on your VR dev journey! And please don't hesitate to ask questions if you get stuck.
