类似panda3d文本打印的课程
panda3d-purses3d的Python项目详细描述
购买3d
我们的目标是尽可能地控制panda3d，同时提供打印到的各种控制台，而不是尽可能地模拟ncurses。它目前还很简陋，但是有了一些解决方法，可以做任何ncurses可以做的事情，除了beep（）。
- 仅适用于包含U+2588“全块”Unicode字符的单行距字体（用于实心字符背景）。出于这个原因，hack.ttf在这个repo中，它是麻省理工学院授权的。
- 用于制作基于ascii/文本的游戏、gui、hud等。
- 要么结合panda3d的其他功能，要么认为这是将文本绘制到屏幕上的错误方法。
要查看功能的彩色显示，请运行
$ git clone http://github.com/momojohobo/panda3d-purses
$ cd panda3d-purses
$ pip install -r requirements.txt
$ python purses3d/__init__.py
它也可以在pypi上使用。
$ pip install panda3d-purses3d
待办事项：
- 从ncurses窃取更多方便的功能。
许可证
无论是麻省理工学院还是公共领域（cc0），你都可以选择。
使用方法：
# Import sys, panda3d and purses
import sys
from direct.showbase.ShowBase import ShowBase
from purses3d import Purses, Window
# Run panda3d
base = ShowBase()
base.accept("escape", sys.exit)
base.run()
# Initialize purses with a console size of 40x20 characters
# It will be automatically scaled to fill the entire screen
purses = Purses(40, 20)
# Make a window in the center, taking up half the screen
window = Window(x=10, y=5, columns=20, lines=10)
# Move that window's cursor to where we want to write
window.move(3, 0)
# Write something in that window
window.addstr("hello world")
# Or move and print in one go
window.addstr(3, 0, "hello world")
# Copy it to the main purses window
purses.copyfrom(window)
# Because Purses() is also a window, we can write something on it too
purses.addstr(0, 0, "purses!")
# Update the screen
purses.refresh()
颜色/属性
要添加颜色（以及其他需要的东西），我们需要panda3d的textpropertiesmanager
from panda3d.core import TextProperties, TextPropertiesManager
# Get panda3d's global property manager
manager = TextPropertiesManager.getGlobalPtr()
# Make some property, in this case something telling it to print the text red (in rgba)
red = TextProperties()
red.setTextColor((1,0,0,1))
# Add it to panda's global mananger
manager.addProperties("myRedColor", red)
# And use it to print the characters foreground (with a transparent background)
purses.addstr(0, 0, "purses!", ("myRedColor", None))
# ...or to print the characters background in that color
purses.addstr(0, 0, "purses!", (None, "myRedColor"))
purses.refresh()
# We can reposition this purses instance too so it doesn't take up the entire screen
purses.node.setScale(0.5)
purses.node.setPos(-0.3, 0, 0)
# Or parent it to the world as a 3d object COOOL!
purses.node.reparentTo(render)
您可以更改在panda3d textproperties类中找到的任何属性，尽管它们大多未经测试。尤其是改变文本大小可能会把事情搞砸。
文本输入
因为panda3d是一个实时系统，而curses不是，所以文本输入的处理方式有点不同。
# Get user input string at (10, 5) from main purses screen
string = purses.getstr(10, 5)
# You can also supply a different window to echo the string to
# Or give it fg and bg attributes
string = purses.getstr(10, 5, window=my_window, attr=("red", "blue"))
# If the string is closed (with enter), it is returned instead of None.
if string:
# If used types hello
if string == "hello":
# Print this answer
purses.addstr("why hello there buddy!")
迄今为止的功能
purses.move(x, y) # Place the cursor at position
purses.increment(n=1) # Increment the cursor location
purses.scrollup() # Scroll everything in window up
purses.scrolldown() # Scroll everything in window down
purses.fill(character) # Fills the entire window with a char (or empty if none is specified)
purses.delete(x, y) # Delete a single character
purses.addch(x, y, char, properties) # Add a single character
purses.addstr(x, y, string, properties) # Add a string
# Draw horizontal and vertical lines respectively
purses.linehori(start_x, start_y, length, character, properties)
purses.linevert(start_x, start_y, length, character, properties)
# Draw a border around the window, left, right, top, bottom and its corners.
# Each character should be complete with properties ("c", (None, None))
purses.border(ls, rs, ts, bs, tl, tr, bl, br)
purses.box(horizontal_sides, vertical_sides)
# These calls only work from the main Purses() window.
purses.refresh() # Refresh screen (place its state to the screen)
# Return the mouse coordinates in characters, only callable from Purses()
# If window is specified it will return its relative coordinates
purses.getmouse(window)
# Return a string as written by user
purses.getstr(x, y, window=None, attr=(None, None))
