4.6 Adding Forces for Realistic Interactions

You can apply directional forces to create effects like pushing or pulling objects.

Example: Pushing an Object
Create a new script called PushObject and attach it to the player:

public float pushForce = 10f;

void OnCollisionEnter(Collision collision) {
    Rigidbody otherRb = collision.gameObject.GetComponent<Rigidbody>();
    if (otherRb != null) {
        Vector3 pushDirection = collision.contacts[0].normal * -1;
        otherRb.AddForce(pushDirection * pushForce, ForceMode.Impulse);
    }
}

Explanation:

• Checks if the collided object has a Rigidbody.
• Calculates the direction of the force based on the collision point.
• Applies an impulse to simulate a push.

Test It: Add a Rigidbody to another object, collide with it, and watch it move.
