如何设置形状

Question

import turtle
s1 = turtle.Screen()
b = turtle.Turtle()
b.shape("turtle")
b.color("blue")
b.speed(9)
s1.bgpic("grass.gif")


########## turtles
t1 = turtle.Turtle()
t1.shape('circle')
t1.pu()
t1.goto(100,200)

t2 = turtle.Turtle()
t2.shape('circle')
t2.pu()
t2.goto(-100,-200)

t3 = turtle.Turtle()
t3.shape('circle')
t3.pu()
t3.goto(200,-200)

t4 = turtle.Turtle()
t4.shape('circle')
t4.pu()
t4.goto(0,200)

t5 = turtle.Turtle()
t5.shape('circle')
t5.pu()
t5.goto(400,300)

用于将乌龟改为下载的gif图像的python turtle命令是什么？我需要将t1-t5更改为gif图像而不是圆圈。

Answer 1

我使用以下代码将图像导入程序：

output: {
  ....
  library: 'server',
  libraryTarget: 'commonjs2'
}

target: 'node'

要将乌龟变成.gif图像，可以将图像添加到形状中。

import turtle

wn = turtle.Screen()
wn.bgcolor('white')

your_image = r"C:\Users\your_name\Pictures\your_image.gif"

wn.addshape(your_image)

Answer 2

对我来说，我想使用 PNG ，而不是 GIF 。最后，我找到了答案，并记录了 GIF 和 PNG 解决方案，以期帮助他人。

t = turtle.Turtle()

# you can change the shape with this command, but you need to tell it what the 'your_shape_name' is.
t.shape('your_shape_name')

如何设置形状

首先，您需要register_shape之前的turtle.Screen()，

等等！在开始之前，请先查看源代码，如下所示：

# Lib/turtle.py

class TurtleScreen(TurtleScreenBase):
    
    ...

    def register_shape(self, name, shape=None):
                
        if shape is None:
            # image
            if name.lower().endswith(".gif"):
                shape = Shape("image", 
                    self._image(name)  # return ``TK.PhotoImage(file=filename)`
                )
            else:
                raise TurtleGraphicsError("Bad arguments for register_shape.\n"
                                          + "Use  help(register_shape)" )
        elif isinstance(shape, tuple):
            shape = Shape("polygon", shape)
        ## else shape assumed to be Shape-instance
        self._shapes[name] = shape
        
    ...

    addshape = register_shape  # <---- so they are the same

确定，然后开始

screen = turtle.Screen()
t = turtle.Turtle()  # a Turtle instance
# t.shape('your_shape_name')  # you can change the shape with this command, but you need tell it what is 'your_shape_name'

if '1. source is png (or anything that is compatible with `tk.PhotoImage`)':    
    your_shape=turtle.Shape('image', tk.PhotoImage(file='your.png')))  # name must is 'image'   
    screen.register_shape(name='your_cool_shape_name', shape=your_shape)
    t.shape('your_cool_shape_name')
    # t.goto(1, 2)
    
if '2 source is gif':
    from pathlib import Path
    your_gif = str(Path('.../your.gif'))
    screen.register_shape(your_gif)
    t.shape(your_gif)
