How to ad gravity on my character controller script?

Hi there,

I'm new to Unity 5 and ain't a programmer. I just found a tutorial on how to create a character controller and now I would like to implement gravity to my spaceship. Is there a simple line of code that could bring that result?

Thanks!!!
Character Controller script found on Youtube:

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(CharacterController))]

public class SpaceNavigation : MonoBehaviour

{
public float MoveSpeed;
public float RotationSpeed;
CharacterController cc;

// Use this for initialization
void Start ()

{
cc = GetComponent<CharacterController>();
}
// Update is called once per frame
void Update () {

Vector3 foward = Input.GetAxis("Vertical") * transform.TransformDirection(Vector3.forward) * MoveSpeed;
transform.Rotate(new Vector3(0,Input.GetAxis("Horizontal") * RotationSpeed * Time.deltaTime,0));
cc.Move(foward * Time.deltaTime);
cc.SimpleMove(Physics.gravity);
}
}
"

 

Have you tried making sure that your character has a rigidbody component attached and then clicking the gravity checkbox?

Also, when posting code please be aware that you can use the tags [.code][./code] (without the periods) before and after your code snippet. It makes it much easier to read the code. Anyway, I hope this helps! good luck!

 

Hi topherbwell, Thank you very much for the response!!!

Yes, but I don't see much difference. The spaceship keeps on floating in mid air when it doesn't collides with the ground until it eventually hits the ground (which takes about 20") I have also tried messing with the values Mass,Drag and ticked Gravity but oddly they don't seem to affect the ship's behavior.

 

I found this thread that may help. http://forum.unity3d.com/threads/gravity-not-working-on-rigidbody.48036/
Maybe try a few of the things listed here and see if any of them fix the issue. Hope something in there helps.

 

This question and answer should clear it up. It's related to the Character Controller itself (the Unity one), not the Rigidbody.

 

Guys thanks again for responding!!! I just found what the issue was!!! I used real scale measurements in Max for my imported objects in Unity (track and spaceship) and they where huge. It was impossible to spot the gravity physics that where going on. However, I still need to adjust the gravity of my ship when that is off the ground; with C# code

So the next question is how small should things be in a game world in relation to the real world in order to work properly?

 

It depends on the game, but if you're a grounded character trying to simulate real life, 1 unit = 1 metre is generally advised. If your game takes place in space though, that's going to be a ridiculous scale.
