unity rigidbody addforce code example

Example 1: Rigidbody.addforce

using UnityEngine;public class ExampleClass : MonoBehaviour
{
    public float thrust = 1.0f;
    public Rigidbody rb;    void Start()
    {
        rb = GetComponent<Rigidbody>();
        rb.AddForce(0, 0, thrust, ForceMode.Impulse);
    }
}

Example 2: how to make rb.addforce 2d

public Rigidbody rb; //make reference in Unity Inspector

public float SpeedX = 0.1f;
public float SpeedY = 0.5f;

rb.AddForce(new Vector2(SpeedX, SpeedY));

Example 3: unity rigidbody addforce

rb = GetComponent<Rigidbody>();
rb.AddForce(new Vector3(1.5f,1.5f,1.5f));

Example 4: rigidbody addforce

using UnityEngine;public class Example : MonoBehaviour
{
    Rigidbody m_Rigidbody;
    public float m_Thrust = 20f;    void Start()
    {
        //Fetch the Rigidbody from the GameObject with this script attached
        m_Rigidbody = GetComponent<Rigidbody>();
    }    void FixedUpdate()
    {
        if (Input.GetButton("Jump"))
        {
            //Apply a force to this Rigidbody in direction of this GameObjects up axis
            m_Rigidbody.AddForce(transform.up * m_Thrust);
        }
    }
}
