Question

我正在开发一个涉及在圆圈中绘制随机像素的项目。我想提高像素的绘制速度。如何更改每秒帧数。我查看了一些示例，但我的代码仍然不起作用。我使用的是Python 3.2.3和pygame 1.9这是我的代码：

from pygame import*
from random import*

screen = display.set_mode((1000,800))
tick = time.Clock()
rand_spraypaint_xs = [] 
rand_spraypaint_ys = []
col1 = (0,0,0)
canvasRect = Rect(100,100,500,500)
tool = 'spraypaint'
draw.rect(screen,(0,255,0),canvasRect,0)
running = True
while running:
    for e in event.get():
        if e.type == QUIT:
            running = False
    mx,my = mouse.get_pos()
    mb = mouse.get_pressed()
    x = randint(mx-30,mx+30)
    y = randint(my-30,my+30)
    dist =(((mx - x)**2 + (my - y)**2)**0.5)

    if dist <=30:
        rand_spraypaint_xs.append(x)
        rand_spraypaint_ys.append(y)
    if canvasRect.collidepoint(mx,my):
        if  tool == 'spraypaint':
            if mb[0]==1:
                screen.set_at((rand_spraypaint_xs[-1], rand_spraypaint_ys[-1]),col1)
                time.wait(1)
                tick.tick(10000)
    display.flip()
quit()

Answer 1

你可以尝试只检查10帧的事件。：

count = 0
while running:
    if count >= 10:
        for e in event.get():
            if e.type == QUIT:
                running = False
    else:
        count += 1

执行此操作的最佳方法是使用for循环。如果将for循环设置为for i in range(10)，它将每帧执行10次操作：

例如：

    from random import*

screen = display.set_mode((1000,800))
tick = time.Clock()
col1 = (0,0,0)
canvasRect = Rect(100,100,500,500)
draw.rect(screen,(0,255,0),canvasRect,0)
running = True
while running:
    for e in event.get():
        if e.type == QUIT:
            running = False
    mx,my = mouse.get_pos()
    mb = mouse.get_pressed()

    if mb[0]:
        for i in range(10): #8 can be changed to whatever value you want 
                            #to make it faster
            p = randint(0, 30), randint(0, 30)
            draw.circle(screen, (0, 0, 0), p, 1)

    tick.tick(100)
    display.flip()
quit()
