Godot UI线程，Task异步和消息弹窗通知
前言
最近我在研究Godot的全局消息，然后发现Godot 也是有UI线程限制的，只能在主线程的子线程里面修改UI。
线程安全
全局消息IOC注入
我之前写过Godot 的IOC注入，这些都是CSDN时期的博客。但是后面CSDN的广告实在是太多了，我就转到博客园里面来了。
Godot.NET C# 工程化开发(1):通用Nuget 导入+ 模板文件导出，包含随机数生成，日志管理，数据库连接等功能
注意，我后面的都是基于我那个IOC框架来写的。
消息窗口搭建
如何修改Label样式可以看我上一篇文章
最简单的消息提示
using Godot;
using Godot_UI_Test.Utils;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Reflection.Emit;
using System.Text;
using System.Threading.Tasks;
namespace Godot_UI_Test.SceneModels
{
public class MessageSceneModel : ISceneModel
{
private PrintHelper printHelper;
private Godot.Label title;
private Godot.Label content;
private VBoxContainer container;
private ColorRect colorRect;
public MessageSceneModel(PrintHelper printHelper) {
this.printHelper = printHelper;
printHelper.SetTitle(nameof(MessageSceneModel));
}
public override void Process(double delta)
{
//throw new NotImplementedException();
}
public override void Ready()
{
printHelper.Debug("加载完成");
colorRect = Scene.GetNode<ColorRect>("ColorRect");
container = colorRect.GetNode<VBoxContainer>("VBoxContainer");
title = container.GetNode<Godot.Label>("Title");
content = container.GetNode<Godot.Label>("Content");
//同步容器大小
container.Size = colorRect.Size;
printHelper.Debug(JsonConvert.SerializeObject(title.Size));
//默认设置为不可见
Scene.Visible = false;
//throw new NotImplementedException();
}
/// <summary>
/// 弹窗延迟退出
/// </summary>
/// <param name="message"></param>
/// <returns></returns>
public async Task ShowInfo(string message)
{
Scene.Visible = true;
printHelper.Debug("Info打印信息");
printHelper.Debug(message);
await Task.Delay(3000);
Scene.Visible = false;
}
}
}
简单使用
虽然有点丑，但是能用
仿Element UI
ElementUI 效果
简单的Label样式
简单的画一下，我就不给具体的参数了，大家点一下就知道了
如何快速加载多个相同节点
如果我们把这个作为场景，又没有那么的复杂。如果用代码生成，写起来很麻烦，也不直观。最好的方法就是复制节点添加。
using Godot;
using Godot_UI_Test.Utils;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Reflection.Emit;
using System.Text;
using System.Threading.Tasks;
namespace Godot_UI_Test.SceneModels
{
public class MessageSceneModel : ISceneModel
{
private PrintHelper printHelper;
private VBoxContainer vBoxContainer;
private AssetsHelper assetsHelper;
private Godot.Label label;
public MessageSceneModel(PrintHelper printHelper, AssetsHelper assetsHelper)
{
this.printHelper = printHelper;
printHelper.SetTitle(nameof(MessageSceneModel));
this.assetsHelper = assetsHelper;
}
public override void Process(double delta)
{
//throw new NotImplementedException();
}
public override void Ready()
{
printHelper.Debug("加载完成");
vBoxContainer = Scene.GetNode<VBoxContainer>("VBoxContainer");
label = Scene.GetNode<Godot.Label>("Label");
//将vBoxContainer居中，GodotProjectSetting是自己设置的
vBoxContainer.Position = new Vector2(GodotProjectSetting.Width/4, 10);
//添加label的靠别，不能直接添加label，因为label已经拥有了父节点
var newLabel = label.Duplicate() as Godot.Label;
//显示Label
newLabel.Visible =true;
vBoxContainer.AddChild(newLabel.Duplicate());
vBoxContainer.AddChild(newLabel.Duplicate());
vBoxContainer.AddChild(newLabel.Duplicate());
//CreateText("te321");
//CreateText("te321 3213 321 3434 4 2 41321 st1 te321 3213 321 3434 4 2 41321 st1 te321 3213 321 3434 4 2 41321 st1");
printHelper.Debug(JsonConvert.SerializeObject(vBoxContainer.Position));
printHelper.Debug(JsonConvert.SerializeObject(vBoxContainer.GetWindow().Position));
//Scene.Visible = false;
//throw new NotImplementedException();
}
private void CreateText(string text)
{
var res = new Godot.Label();
res.AddThemeStyleboxOverride("normal", assetsHelper.MessageItemStyle);
res.AutowrapMode = TextServer.AutowrapMode.WordSmart;
res.HorizontalAlignment = HorizontalAlignment.Center;
res.Text = text;
res.CustomMinimumSize = new Vector2(200, 0);
label = res;
vBoxContainer.AddChild(res);
}
/// <summary>
/// 延迟打印
/// </summary>
/// <param name="message"></param>
/// <returns></returns>
public async Task ShowInfo(string message)
{
printHelper.Debug("Info打印信息");
}
}
}
修改一下，IOC按钮事件注册
using Godot;
using Godot_UI_Test.Utils;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Reflection.Emit;
using System.Text;
using System.Threading.Tasks;
namespace Godot_UI_Test.SceneModels
{
public class MessageSceneModel : ISceneModel
{
private PrintHelper printHelper;
private VBoxContainer vBoxContainer;
private AssetsHelper assetsHelper;
private Godot.Label label;
public MessageSceneModel(PrintHelper printHelper, AssetsHelper assetsHelper)
{
this.printHelper = printHelper;
printHelper.SetTitle(nameof(MessageSceneModel));
this.assetsHelper = assetsHelper;
}
public override void Process(double delta)
{
//throw new NotImplementedException();
}
public override void Ready()
{
printHelper.Debug("加载完成");
vBoxContainer = Scene.GetNode<VBoxContainer>("VBoxContainer");
label = Scene.GetNode<Godot.Label>("Label");
//将vBoxContainer居中，GodotProjectSetting是自己设置的
vBoxContainer.Position = new Vector2(GodotProjectSetting.Width/4, 10);
//CreateText("te321 3213 321 3434 4 2 41321 st1 te321 3213 321 3434 4 2 41321 st1 te321 3213 321 3434 4 2 41321 st1");
printHelper.Debug(JsonConvert.SerializeObject(vBoxContainer.Position));
printHelper.Debug(JsonConvert.SerializeObject(vBoxContainer.GetWindow().Position));
//Scene.Visible = false;
//throw new NotImplementedException();
}
/// <summary>
/// 挂载Label
/// </summary>
/// <param name="text"></param>
private Godot.Label CreateText(string text)
{
var newLabel = label.Duplicate() as Godot.Label;
newLabel.Text = text;
newLabel.Visible=true;
vBoxContainer.AddChild(newLabel);
return newLabel;
}
/// <summary>
/// 延迟打印
/// </summary>
/// <param name="message"></param>
/// <returns></returns>
public async Task ShowInfo(string message)
{
printHelper.Debug("Info打印信息");
var newLabel = CreateText(message);
await Task.Delay(3 * 1000);
newLabel.Free();
}
}
}
总结
我只是很潦草的实现了消息弹窗这个功能，还没加动画效果。不过这个确实让我学到了很多，尤其是节点挂载这个事情。
