Walking around a sphere in Lumberyard

Question

I am trying to create a simple game using Amazon Lumberyard and my goal is to have levels/stages where the player will be able to walk around a mini planet.

I have seen a lot of tutorials about this for Unity, but I find it hard to try to translate this into Lua.

My problem is trying to make the "Feet" of the character point towards the planet. Any help would be appreciated.

the script I got for unity is below,

Planet

public class PlanetScript : MonoBehaviour {

public float gravity = -12;

public void Attract(Transform playerTransform)
{
    Vector3 gravityUp = (playerTransform.position - transform.position).normalized;
    Vector3 localUp = playerTransform.up;

    playerTransform.GetComponent<Rigidbody>().AddForce(gravityUp * gravity);

    Quaternion targetRotation = Quaternion.FromToRotation(localUp, gravityUp) * playerTransform.rotation;
    playerTransform.rotation = Quaternion.Slerp(playerTransform.rotation, targetRotation, 50f * Time.deltaTime);
    }
}

and the player has

void FixedUpdate()
{
    if (attractorPlanet)
    {
        attractorPlanet.Attract(playerTransform);
    }
}

Answer 1

My Lua is pretty rusty but functionally there are several ways to do this. The easiest may be to set your characters rotation (Quaternion or Vector). If you create a new vector which is the result of playerPosition - planetPosition, you want to make this your players new Up Vector (I would normalize this vector).

You can either a) get the rotation of this vector and then set your players rotation vector. Or b) convert this vector to a quaternion and then setting your players rotation quaternion.

Quaternions are the best!
