Showcase Unity3D Movement script that works with RigidBody.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class SubsribeToSodiium:) : MonoBehaviour
7. {
8. // Create a Tag on your in-game terrain called OnTerrain
9.     public float MoveSpeed,  HorizontalSpeed, gravityForce, JumpForce;
10.     public bool OnTerrain;
11.     public Rigidbody RB;
12.  
13. void OnTriggerEnter (collider other)
14. {
15. if (other.tag == "OnTerrain")
16. {
17. OnTerrain = true;
18. }
19. void OnTriggerExit (collider other)
20. {
21. OnTerrain = false;
22. }
23. }
24.     {
25.         //Character Movement
26.               RB.velocity = new Vector3(Input.GetAxis("Horizontal") * MoveSpeed, RB.velocity.y, -MoveSpeed);
27.  
28.         //Jumping & Physics
29.         Physics.gravity = (new Vector3(0, gravityForce, 0));
30.         if (Input.GetKey(KeyCode.Space) && OnTerrain == true)
31.         {
32.             RB.AddForce(new Vector3(0, JumpForce, 0), ForceMode.Impulse);
33.         }
34. }
