conye – Unity2

Some reminders for myself:

• Start function => void Start()
• update function called repeatedly => void Update()
• Debug.Log
• Do while loops do{} while() checks exit condition at end
• For each loop is written “foreach(type item in arr)”
• string is lowercase
• if a var is declared public, other scripts can edit it, and it shows up in the inspector!
• Hierarchy is:  start/update set var > inspector set var > class set var
• Private is the default access modifier
• Access another class => 
• 
• 
• Awake called before start
• Fixed update for physics -> called regularly
• Update times vary
• Get time with Time.deltaTime
• 
• Vector3.Cross(VectorA, VectorB)
• If I want to get a component of the thing my script is attached to. Type Mything = getComponent<Type>();
• We can use “enabled” property to toggle components on and off
• Can also use “active” to toggle GameObjects on and off

• 
• mult by time.deltaTime moves it in meters per second instead of meters per frame
• Vector3.forward, Vector3.up is a shortcut
• Input.getKey(KeyCode.UpArrow), there’s also getButton => these return true or false based on if they’re pressed or not.
• getAxis: => [-1, 1]
• can detect mouseclicks on gui or colliders => OnMouseDown()
• rigidBody(addForce())
• Destroy to destroy game objects, use it for other objects/ components that the script isn’t actually attached to, can include timed delay
• getComponent is expensive
• subclass example => 
• Use instantiate to duplicate prefabs
• helpful link for ref => https://unity3d.com/learn/tutorials/topics/scripting/instantiate?playlist=17117
• Invoke and InvokeRepeating(func, delay, subsequentDelays)
