Instantiate

// Create a GameObject
Instantiate(GameObject prefab);
Instantiate(GameObject prefab, Transform parent);
Instantiate(GameObject prefab, Vector3 position, Quaternion rotation);
Instantiate(bullet);
Instantiate(bullet, bulletSpawn.transform);
Instantiate(bullet, Vector3.zero, Quaternion.identity);
Instantiate(bullet, new Vector3(0, 0, 10), bullet.transform.rotation);

Find GameObjects

GameObject.Find("NAME IN HIERARCHY");

GameObject.FindWithTag("TAG");
GameObject.FindGameObjectWithTag("TAG");
GameObject.FindGameObjectsWithTag("TAG");

GameObject.FindObjectOfType<Rigidbody>();
GameObject.FindObjectsOfType<Rigidbody>();

Navigate Hierarchy

// Get first child GameObject
parent­Gam­eOb­jec­t.t­ran­sfo­rm.G­et­Child(0);

// Add Component to GameObject
gameObject.A­dd­Com­pon­ent­<Rigidbody>();

// Get Component from GameObject
gameObject.G­et­Com­pon­ent­<Rigidbody>();

Destroy

Destroy(gameObject);

// Do not destroy the target Object when loading a new Scene
DontDestroyOnLoad(gameObject);

Accessing Components

// Current GameObject
Rigidbody rb = GetComponent<Rigidbody>();
Rigidbody[] rb = GetComponents<Rigidbody>();

// Children
Rigidbody rb = GetComponentInChildren<Rigidbody>();
Rigidbody[] rb = GetComponentsInChildren<Rigidbody>();

// Parent
Rigidbody rb = GetComponentInParent<Rigidbody>();
Rigidbody[] rb = GetComponentsInParent<Rigidbody>();

Rigidbody

Collisions

Both the Rigidbody and the targeted GameObject needs to have a Collider attached. If they have the Physics will interact and the OnCollisionEnter() event will trigger.

Actions

rb.AddForce(Vector3.up * 10, ForceMode.Impulse);

Adds a jump/force to the Rigidbody in a Y-axis direction.
