在Cocos2d中,改变按钮(`Button`)的边框样式通常涉及到自定义节点(`Widget`),你可以通过覆盖`draw()`函数来实现。以下是一个基本的例子,展示了如何创建一个自定义按钮,并改变其边框风格:
```python
from cocos.layer import Layer
from cocos.sprite import Sprite
from cocos.director import director
from cocos.actions import *
from cocos.ui.widget import Widget, TextButton
class CustomButton(Widget):
def __init__(self, text, border_width=2, border_color=(0, 0, 0), *args, **kwargs):
super().__init__(*args, **kwargs)
self.text = text
self.button_label = TextButton(text=text, font_size=48)
self.button_label.position = (self.width // 2, self.height // 2)
self.add(self.button_label)
# 自定义draw()函数,设置边框
def draw(self):
if hasattr(self, "button_label"):
border_color = list(map(int, border_color))
p = director.get_window_surface().get_pixel()
left_top = (int(self.button_label.x - border_width / 2), int(self.button_label.y - border_width / 2))
right_bottom = (int(self.button_label.x + self.button_label.width + border_width / 2), int(self.button_label.y + self.button_label.height + border_width / 2))
for x in range(left_top[0], right_bottom[0]):
for y in range(left_top[1], right_bottom[1]):
r, g, b, a = p(x, y)
if all([r == color, g == color, b == color]) and a != 0:
p(x, y) = border_color + (a,) # 给边框上色
# 使用自定义按钮
custom_button = CustomButton('Custom Button', border_width=5, border_color=(255, 0, 0))
custom_layer = Layer(custom_button)
director.run(custom_layer)
```
在这个例子中,我们创建了一个名为`CustomButton`的类,它继承了`Widget`并重写了`draw()`方法。当按钮需要显示时,我们将自定义的文本按钮添加到新的`Layer`中。
