這裡我先用javaScript 呈現，C# 出了一些很嚴重的CanVas的問題。

OpenString 腳本(按鈕控制) :

#pragma strict

var locked : boolean = true;

var colorNumberSw : int = 0;

function OnGUI(){

if(GUI.Button(Rect(Screen.width/Screen.width, Screen.height/Screen.height, 100, 50),"Open canvas")){

locked = !locked;

}

if(GUI.Button(Rect(Screen.width/Screen.width, Screen.height/Screen.height + 60, 100, 50),"Red")){

colorNumberSw = 1;

}

if(GUI.Button(Rect(Screen.width/Screen.width, Screen.height/Screen.height + 120, 100, 50),"Green")){

colorNumberSw = 2;

}

if(GUI.Button(Rect(Screen.width/Screen.width, Screen.height/Screen.height + 180, 100, 50),"Yellow")){

colorNumberSw = 3;

}

if(GUI.Button(Rect(Screen.width/Screen.width, Screen.height/Screen.height + 240, 100, 50), "Return Game")){

Application.LoadLevel("CanVasTest");

Application.Quit();

Unity 滑鼠控制角色移動 - 射線及Animator 動畫控制方法

匯入模型後請把RIG 按鈕底下 Animation type 選擇 Humanoid 在按下Apply。

 

再Project 視窗按下右鍵建立 Animator Controller ，在點兩下就會進入Animator 
編輯視窗。

把模型動畫以動作邏輯順序方式拖曳進去Animator 編輯視窗。

再動畫編輯區塊按下右鍵選擇Make Transitionm，會出現

箭頭再指向另一個動畫編輯區塊。

※ 注意: 箭頭方向一定要注意動畫編輯區塊的正確位置。

  箭頭方向位置表示動畫撥放的動畫區塊。

之後再Parameters 視窗 點選上面的" + " 這個符號，

再選擇所需的程式控制的基本型別，選完型別後

請把型別視窗命名。

※注意: 在這裡我使用Boolean 型別 程式控制:  SetBool。

Float 型別 程式控制: SetFloat。                

Int 型別 程式控制: SetInteger。                 

Trigger 類型 程式控制: SetTrigger。           

               命名很重要 程式控制的地方及數值，特別注意。        

     

再點選箭頭後，旁編列會出現箭頭所需編輯視窗。

Condition 屬性視窗選擇，型別命名名稱，再調整所需數值。

※注意: Condition 屬性視窗的數值，由程式撰寫那邊控制設定。
