我想在ursina的下拉按鈕中更改字體或寬度，有什么幫助嗎？歡呼。
我的簡單下拉按鈕如下
from ursina import * # Import the ursina engine
from ursina.prefabs.dropdown_menu import DropdownMenu, DropdownMenuButton
app = Ursina() # Initialise your Ursina app
def val_but(txt):
print(txt)
DropdownMenu(text='File', buttons=(
DropdownMenuButton('New', on_click = val_but('New')),
DropdownMenuButton('Open'),
DropdownMenu('Reopen Project', buttons=(
DropdownMenuButton('Project 1'),
DropdownMenuButton('Project 2'),
)),
DropdownMenuButton('Save'),
DropdownMenu('Options', buttons=(
DropdownMenuButton('Option a'),
DropdownMenuButton('Option b'),
)),
DropdownMenuButton('Exit'),
), scale=(.2,.05), text_origin=(0,0), position=(-.58,.37))
app.run() # Run the app
我找到了如何更改比例、text_origin 和位置，如您在最后一行中看到的那樣，但仍在尋找更改下拉按鈕內部文本的字體和寬度
uj5u.com熱心網友回復：
我自己發現了一種更改字體的方法并希望分享它，我覺得有一種更有效的方法，但無論如何：
第一步：復制當前ursina目錄下的字體檔案。
第二步：使用text_entity.font屬性。
這是一個作業示例：
from ursina import * # Import the ursina engine
from ursina.prefabs.dropdown_menu import DropdownMenu, DropdownMenuButton
app = Ursina() # Initialise your Ursina app
def val_but(txt):
print(txt)
class DropdownMenuButton(Button):
def __init__(self, text='', **kwargs):
super().__init__(
scale=(.3,.025),
origin=(-.5, .5),
color=color.azure,
pressed_scale=1,
text=text,
**kwargs
)
print(str(self.text_entity.width))
self.text_entity.scale_y=1.4
self.text_entity.scale_x=.25
self.text_entity.font='AbyssinicaSIL-Regular.ttf'
print(str(self.text_entity.width))
self.on_click = self.test_but
def test_but(self):
print(self.text)
class DropdownMenu(DropdownMenuButton):
def __init__(self, text='', buttons=list(), **kwargs):
super().__init__(text=text)
self.position = window.top_left
self.buttons = buttons
for i, b in enumerate(self.buttons):
b.world_parent = self
b.original_scale = b.scale
b.x = 0
b.y = -i-1 *.98
b.enabled = False
if isinstance(b, DropdownMenu):
for e in b.buttons:
e.x = 1
e.y = 1
self.arrow_symbol = Text(world_parent=self, text='>', origin=(.5,.5), position=(.95, 0), color=color.gray)
for key, value in kwargs.items():
setattr(self, key, value)
def open(self):
for i, b in enumerate(self.buttons):
invoke(setattr, self.buttons[i], 'enabled', True, delay=(i*.02))
def close(self):
for i, b in enumerate(reversed(self.buttons)):
b.enabled = False
def on_mouse_enter(self):
super().on_mouse_enter()
self.open()
def input(self, key):
if key == 'left mouse down' and mouse.hovered_entity and mouse.hovered_entity.has_ancestor(self):
self.close()
def update(self):
if self.hovered or mouse.hovered_entity and mouse.hovered_entity.has_ancestor(self):
return
self.close()
window.title = 'My Game' # The window title
window.icon = 'tigre.ico'
window.borderless = False # Show a border
window.fullscreen = False # Do not go Fullscreen
# window.exit_button.visible = False # Do not show the in-game red X that loses the window
window.fps_counter.enabled = True # Show the FPS (Frames per second) counter
DropdownMenu(text='File', buttons=(
DropdownMenuButton('New'),
DropdownMenuButton('Open'),
DropdownMenu('Reopen Project', buttons=(
DropdownMenuButton('Project 1'),
DropdownMenuButton('Project 2'),
)),
DropdownMenuButton('Save'),
DropdownMenu('Options', buttons=(
DropdownMenuButton('Option a'),
DropdownMenuButton('Option b'),
)),
DropdownMenuButton('Exit'),
), scale=(.4,.05), text_origin=(0,0), position=(-.58,.37),
color=color.pink)
def input(key):
print(key)
app.run() # Run the app
感謝口袋妖怪的建議。
