unity3d - Unity3d - 一次两个输入按钮 - 事件触发延迟

Question

我正在为两个玩家制作游戏。他们都有一个按钮，可以按下该按钮为电表充电，然后根据他们为电表充电的时间松开以执行操作。

我使用左移和右移作为两个播放器按钮。

问题是，如果它们同时充电，当其中一个释放按钮时，该Input.GetButtonUp事件直到半秒后才会触发。如果只有一名玩家在冲锋，则在他释放时立即触发该事件。

任何想法为什么以及如何解决它？它发生在两台不同的PC上。

using UnityEngine;
using System.Collections;

public class ObjectScript : MonoBehaviour {
    void Update () {            
        for (int i = 0; i < 2; i++) {
            if (isButtonDown(i))        // button first pressed
                buttonDown(i);
            if (isButtonUp(i))          // button released
                buttonUp(i);
            if (isButtonPressed(i))     // while button held pressed
                buttonIsPressed(i);
        }
    }

    // checks whether button has just been pressed down for given player
    private bool isButtonDown(int player) {
        return Input.GetButtonDown(getPlayerKeyName(player));
    }

    // checks whether button is held pressed down for given player
    private bool isButtonPressed(int player) {
        return Input.GetButton(getPlayerKeyName(player));
    }

    // checks whether has just been released for given player
    private bool isButtonUp(int player) {
        return Input.GetButtonUp(getPlayerKeyName(player));
    }

    // get the name of the key per player
    private string getPlayerKeyName(int player) {
        return "Player" + (player+1).ToString() + "Key";
    }

    // when button is first pressed
    private void buttonDown(int player) {
        Debug.Log("Button pressed: " + player.ToString());
    }


    // while button is pressed
    private void buttonIsPressed(int player) {
    }

    // when button is first released
    private void buttonUp(int player) {
        Debug.Log("Button released: " + player.ToString());
    }
}
