pyglet中的平滑运动

因此，在将Tkinter用于我们的游戏之后，我们决定移至Pyglet。但是我遇到的问题之一是运动，在Tkinter中，我能够制作出平滑的运动系统，但是在pyglet中，我所能做的就是让角色以抖动的方式运动。

import pyglet
from pyglet.window import key, Window
from pyglet import clock
from threading import Timer

X = 5 #Speed of the player
w = 0 #Controls +y movement
a = 0 #Controls -x movement
s = 0 #Controls -y movement
d = 0 #Controls +x movement

window = Window(width = 500, height = 500) #Defines window

MainChar = pyglet.image.load("Mainchar.png") #Loads the Mainchar.png
Player = pyglet.sprite.Sprite(MainChar, x = 0, y = 0) #Makes MainChar into a sprite

@window.event
def on_key_press(symbol, modifiers): #Looks for a keypress
    print("keypress")
    if symbol == key.W:
        global w
        global a
        global s
        global d
        w = True
    elif symbol == key.A:
        a = True
    elif symbol == key.S:
        s = True
    elif symbol == key.D:
        d = True

@window.event
def on_key_release(symbol, modifiers):
    print("keyup")
    if symbol == key.W:
        w = False
    elif symbol == key.A:
        a = False
    elif symbol == key.S:
        s = False
    elif symbol == key.D:
        d = False
@window.event
def moveT():
    print("cycle")
    def moveD():
        if w == True:
            Player.y += 0.1
        elif a == True:
            Player.x -= 5
        elif s == True:
            Player.y -= 5
        elif d == True:
            Player.x += 5
        moveT()
    moveTimer = Timer(0.01, moveD)
    moveTimer.start()

@window.event
def on_draw():
    window.clear()
    Player.draw()

moveT()
pyglet.app.run()

我将w，a，s和d作为布尔值的原因是这样，因此我可以在按住键而不是按键的情况下移动字符。

任何帮助将是美好的，在此先感谢！

问题是您使用pythons threading。这不会触发pyglet窗口重绘。
您必须使用pyglet.clock和计划每次时钟打勾时要调用的函数。这也导致pyglet窗口也被更新，并且on_draw()事件被触发。例如：

@window.event
def moveT(dt):

    if w == True:
        Player.y += 0.1
    elif s == True:
        Player.y -= 5

    if a == True:
        Player.x -= 5
    elif d == True:
        Player.x += 5

pyglet.clock.schedule_interval(moveT, 1 / 60)

进一步w，a，s并且d都需要申报global的on_key_release，太。

import pyglet
from pyglet.window import key, Window
from pyglet import clock

X = 5 #Speed of the player
w, a, s, d = False, False, False, False 

window = Window(width = 500, height = 500) #Defines window

MainChar = pyglet.image.load("Mainchar.png")
Player = pyglet.sprite.Sprite(MainChar, x = 0, y = 0)

@window.event
def on_key_press(symbol, modifiers): #Looks for a keypress
    global w, a, s, d
    if symbol == key.W:
        w = True
    elif symbol == key.A:
        a = True
    elif symbol == key.S:
        s = True
    elif symbol == key.D:
        d = True

@window.event
def on_key_release(symbol, modifiers):
    global w, a, s, d
    if symbol == key.W:
        w = False
    elif symbol == key.A:
        a = False
    elif symbol == key.S:
        s = False
    elif symbol == key.D:
        d = False

@window.event
def moveT(dt):

    if w == True:
        Player.y += 0.1
    elif s == True:
        Player.y -= 5

    if a == True:
        Player.x -= 5
    elif d == True:
        Player.x += 5

@window.event
def on_draw():
    window.clear()
    Player.draw()

pyglet.clock.schedule_interval(moveT, 1 / 60)
pyglet.app.run()
