Object and Component

• active an object
  • prefab is an object
• enable a component
  • any script under an object is a component
  • renderer is a component
• GameObject.Find不能找被隱藏的物件/setActive(false)

變數在不同區域(scope)的優先權

由上例，最後myInt為11

另外如果沒有在Start( )做初始化/指定數值，而且myInt又是宣告成public的情形下，那會以Inspector的數值為優先

結論：

A: 在宣告區

B: 在Start( )

C: 在Inspector (在runtime之前/在遊戲開始之前)

優先權 B > C > A

Awake( )與Start( )

說明

範例

Update( ) vs FixedUpdate( )

Update( )

• call every frame
• but interval time between frames is vary
• used for regular updates:
  • non-physics objects movement
  • simple timers
  • receive input

FixedUpdate( )

• call every physics step (called in regular timeline)
• called interval time are constant
• used for adjusting physics (RB) objects
