如何更改按钮文字的颜色？

debugcn 发表于 Dev

棕褐色

我想单击一个按钮并更改其文本的颜色和消息属性。

我得到了更改其颜色的按钮，但是我需要更改其文本的颜色之一。

private void TurnGreen(Button button)
{
    ColorBlock colors = button.colors;
    colors.normalColor = Color.green;
    button.colors = colors;
}

上面的代码更改了我喜欢的按钮颜色，但是我宁愿更改按钮的文本。但是请注意，我的按钮有两个text-childs。我要更改的文本的名称为“矿石”。

很久没有做Unity了，所以我的知识有点生锈。确保using System.Linq;已在脚本中设置。

        // Considering that "button" is the one on which you clicked.
        // By definition, we have 2 Text children (for single Text, we 
        // could use button.GetComponentInChildren<Text>().color directly, as it returns single element.
        var oreText = button.GetComponentsInChildren<Text>().FirstOrDefault(o => o.name == "Ore"); // Unity allows same naming...
        // I had 2 Text components initially returned: Ore and Wood. 
        // Got the Ore text component with FirstOrDefault. Now check it really exists and set color.            
        if (oreText != null) // Long way to compare. For illustration.
        {
            oreText.color = Color.green;
        }
        // Also, if "Ore" button really exists, you can directly set it from "Single" method:
        // button.GetComponentsInChildren<Text>().Single(o => o.name == "Ore").color = Color.green;
