[Unity&C#]输入任意按键返回对应的字符串

本文参考 参考资料1，探究

按钮按下，调用函 数StartAssignment

public void StartAssignment(string keyName){if(!waitingForKey)StartCoroutine(AssignKey(keyName));}

StarCoroutine 是开启一个协程，参考 参考资料2、3

进入协程函数

/*AssignKey takes a keyName as a parameter. The * keyName is checked in a switch statement. Each * case assigns the command that keyName represents * to the new key that the user presses, which is grabbed * in the OnGUI() function, above. */public IEnumerator AssignKey(string keyName){waitingForKey = true;yield return WaitForKey(); //Executes endlessly until user presses a keyswitch(keyName){case "forward":GameManager.GM.forward = newKey; //Set forward to new keycodebuttonText.text = GameManager.GM.forward.ToString(); //Set button text to new keyPlayerPrefs.SetString("forwardKey", GameManager.GM.forward.ToString()); //save new key to PlayerPrefsbreak;case "backward":GameManager.GM.backward = newKey; //set backward to new keycodebuttonText.text = GameManager.GM.backward.ToString(); //set button text to new keyPlayerPrefs.SetString("backwardKey", GameManager.GM.backward.ToString()); //save new key to PlayerPrefsbreak;case "left":GameManager.GM.left = newKey; //set left to new keycodebuttonText.text = GameManager.GM.left.ToString(); //set button text to new keyPlayerPrefs.SetString("leftKey", GameManager.GM.left.ToString()); //save new key to playerprefsbreak;case "right":GameManager.GM.right = newKey; //set right to new keycodebuttonText.text = GameManager.GM.right.ToString(); //set button text to new keyPlayerPrefs.SetString("rightKey", GameManager.GM.right.ToString()); //save new key to playerprefsbreak;case "jump":GameManager.GM.jump = newKey; //set jump to new keycodebuttonText.text = GameManager.GM.jump.ToString(); //set button text to new keyPlayerPrefs.SetString("jumpKey", GameManager.GM.jump.ToString()); //save new key to playerprefsbreak;}yield return null;}

等待 按下任意键

协程函数

//Used for controlling the flow of our below CoroutineIEnumerator WaitForKey(){while(!keyEvent.isKey)yield return null;}

参考参考资料5
PlayerPrefs.SetString

Sets the value of the preference identified by key.
