1.效果
2.源码
3.用法
注意:
pygame2.0已经支持输入法了,本文的方法仅供参考
为了解决pygame不能输入中文的问题,就写了一个中文输入框
1.效果 2.源码以下代码需要安装:
pip install Pinyin2Hanzi
然后就可以直接运行啦
注意:你电脑里如果没有microsoftyaheimicrosoftyaheiui字体的话,请自行找一个中文字体
import string

3.用法用法很简单
1.创建一个TextBox对象
TextBox参数说明:
w:输入框的宽
h:输入框的高
x:输入框左上角x坐标
y:输入框左上角y坐标
font:字体(可以不传)
callback:按下回车之后的回调函数,这个函数必须有一个参数用来接收文本框中的字符串
2.在键盘按下事件时调用TextBox对象的safe_key_down(event)方法,记住要把pygame的event传进去
3.记得调用TextBox的draw(surface)方法,显示输入框
