Debugging

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {
	public void GoToScene(){
		Debug.log("My method was called!")	
	}
}

Scene Changing

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class NewBehaviourScript : MonoBehaviour {
	public void GoToScene(){
		Debug.log("My method was called!");
		SceneManager.LoadScene("00-FallingCoconut");
	}
}

The Variables

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class NewBehaviourScript : MonoBehaviour {
	public void GoToScene(string sceneName){
		Debug.log("My method was called!");
		SceneManager.LoadScene("sceneName");
	}
}

-Allow you to store a GameObject, all of its components, and settings in a file on your hard disk
-Think of prefabs as a “plan” that Unity follows to create certain GameObjects

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

	public GameObject objectToCreate;

	// Use this for initialization
	void Start () {
		// make an object
		// Object.Instantiate(objectToCreate, new Vector3(2,4,6), Outereign.identity);
		for (int i = 0; i < 50; i++){
			// Object.Instantiate(objectToCreate, new Vector3(i,4,6), Outereign.identity);
			GameObject newSeaqull = (GameObject)Object.Instantiate(objectToCreate, new Vector3(1, 8, 0), Quatereign.identity);
			Render objectRenderer = newSeaqull.GetComponentInChildren<Renderer>();
			objectRenderer.material.color = Color.whilte * Random.value;
		}
	}
	
	// Update is called once per frame
	void Update () {

	}
}

-This is how specify positions in 3D space
-Creates a new Vector3 object
-First number is the x coordinate
-Second number is the y coordinate
-Third number is the z coordinate

Quaternions
-How Unity handles 3D rotations
-Better for simulations than Euler angles
-Unity handles all the complicated math

Comments
-Great way to write programming notes to yourself and others
-Also useful for saving code for later reference

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

	public GameObject objectToCreate;

	// Use this for initialization
	void Start () {
		// make an object
		// Object.Instantiate(objectToCreate, new Vector3(2,4,6), Outereign.identity);
		for (int i = 0; i < 1000; i++){
			Object.Instantiate(objectToCreate, new Vector3(i,4,6), Outereign.identity);
		}
	}
	
	// Update is called once per frame
	void Update () {

	}
}

Creating Objects using Code
– This is called Instantiating
– You are creating a new instance of something

References
References allow to drag-and-drop objects into code using the Unity Editor.

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

	public GameObject objectToCreate;

	// Use this for initialization
	void Start () {
		// make an object
		Object.Instantiate(objectToCreate, new Vector3(2,4,6), Outereign.identity);
	}
	
	// Update is called once per frame
	void Update () {

	}
}

Update() Method
– called every frame
– For VR, this might be called 60, 90, or even 120 times per second.

This speed depends on hardware and a variety of software factors

Time.deltaTime
– Gives you smooth framerate-independent animation
– Contains the amount of time it took to render the previous frame
– Changes every frame

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		if (transform.position.y > 0.5f){
			transform.Translate (0, -2.5 * Time.daltaTime, 0, Space.World);
		}		
	}
}

scripting API

-Divided into namespaces.
-Namespaces establish a groupings between related objects
-Almost all scripts start with using UnityEngine;
-This gives you access to all the objects in the UnityEngine namespace

Camera.background-Color
https://docs.unity3d.com/ScriptReference/Camera-backgroundColor.html

A dog object might have
“bark” behavior
“walk around” behavior
“love humans” behavior

Scripts describe behaviors that get attached to Game Objects

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
		transform.Translate (0, -2.5 * Time.daltaTime, 0, Space.World);
	}
}
