Device Simulator 支持用插件来扩展其功能,并在 Simulator 视图中更改控制面板的__ UI__(即用户界面,User Interface)让用户能够与您的应用程序进行交互。Unity 目前支持三种 UI 系统。更多信息
See in Glossary。
要创建 Device Simulator 插件,请扩展 DeviceSimulatorPlugin 类。
要将 UI 插入到 Device Simulator 视图中,插件必须:
title 属性以返回非空字符串。OnCreateUI 方法以返回包含 UI 的 VisualElement。如果插件不符合这些条件,Device Simulator 会实例化插件,但不会在 Simulator 视图中显示其 UI。
以下示例演示了如何创建覆盖游戏作品属性,并将 UI 添加到 Simulator 视图的插件。
public class TouchInfoPlugin : DeviceSimulatorPlugin
{
public override string title => "Touch Info";
private Label m_TouchCountLabel;
private Label m_LastTouchEvent;
private Button m_ResetCountButton;
[SerializeField]
private int m_TouchCount = 0;
public override void OnCreate()
{
deviceSimulator.touchScreenInput += touchEvent =>
{
m_TouchCount += 1;
UpdateTouchCounterText();
m_LastTouchEvent.text = $"Last touch event: {touchEvent.phase.ToString()}";
};
}
public override VisualElement OnCreateUI()
{
VisualElement root = new VisualElement();
m_LastTouchEvent = new Label("Last touch event: None");
m_TouchCountLabel = new Label();
UpdateTouchCounterText();
m_ResetCountButton = new Button {text = "Reset Count" };
m_ResetCountButton.clicked += () =>
{
m_TouchCount = 0;
UpdateTouchCounterText();
};
root.Add(m_LastTouchEvent);
root.Add(m_TouchCountLabel);
root.Add(m_ResetCountButton);
return root;
}
private void UpdateTouchCounterText()
{
if (m_TouchCount > 0)
m_TouchCountLabel.text = $"Touches recorded: {m_TouchCount}";
else
m_TouchCountLabel.text = "No taps recorded";
}
}
