Question

我一直试图弄清楚这一点，但没有成功。我想要做的是在脚本在旧文本下添加新文本时保留旧文本。

public GameObject Text_Object;
private Text textComponent;
void Start () 
{
    //gets the text UI Object in canvas component
    textComponent = Text_Object.GetComponent<Text>();
    textComponent.text = "Hello";
    Text2();
}

void Text2()
{
    textComponent.text = "Hey";
}

基本上你可以看到第一个文本被替换为第二个文本。我正在尝试做的是保留旧文本，而如果我按T它会在旧文本下方打印新文本，并在它们点击D时添加命令，它会清除文本新旧文本。 Image of what I am talking about

已更新

public GameObject Text_Object;
private Text textComponent;

void AppendText(string text)
{
    string current = textComponent.text;
    if(string.IsNullOrEmpty(current) || current.Trim().Length == 0)
    {
        current = text;
    }
    else
    {
        current += string.Format("\r\n{1}", text);
    }
    textComponent.text = current;
}
// Use this for initialization
void Start () {
    textComponent = Text_Object.GetComponent<Text>();
    textComponent.text ="Hello1";
    Welcome ();
}

// Update is called once per frame
void Update () {
    if (Input.GetKey (KeyCode.D)) {
        textComponent.text = string.Empty;
    }
}

void Welcome (){
    textComponent.text = "Hello";
    textComponent.text = "Hello2";

}

欢迎来到SO。你的问题对我来说似乎有点不清楚，但如果我说得对，你想要这样的事情：

   <Page>
        <Page.Resources>
                <Style TargetType="{x:Type Button}" x:Key="NonFocusButton">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type Button}">
                            <Border Name="Border" 
                        Background="Blue"
                        BorderBrush="Blue">
                            </Border>
                            <ControlTemplate.Triggers>
                                <Trigger Property="Button.IsPressed" Value="True">
                                    <Setter TargetName="Border" Property="BorderBrush" Value="Blue" />
                                </Trigger>
                                <Trigger Property="IsMouseOver" Value="true">
                                    <Setter TargetName="Border" 
                              Property="Background" Value="Blue" />
                                </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>

        <Button x:Name"myButton" Style="{StaticResource NonFocusButton}" /> //Assign style here
        </Page.Resources>
    </Page>

希望有所帮助

您可以创建方法AppendText，然后格式化输入参数并将其附加到当前文本：

void AppendText(string text)
{
    string current = textComponent.text;
    if(string.IsNullOrWhiteSpace(current))
    {
        current = text;
    }
    else
    {
        current += string.Format("\r\n{1}", text);
    }
    textComponent.text = current;
}

现在你所要做的就是调用AppendText方法：

AppendText("hello");
AppendText("world");
AppendText("!");

结果应如下所示：

hello
world
!

编辑：

（如果出现错误消息System.string does not contain a definition for IsNullOrWhiteSpace）

而不是：

if (string.IsNullOrWhiteSpace(current))

使用：

if(string.IsNullOrEmpty(current) || current.Trim().Length == 0)

（清除文字）

您可以创建一个方法，然后将其固定到UnityEvent：

public void ClearText()
{
    textComponent.text = string.Empty;
}

如何保留旧行文字？
