pygame實現(xiàn)方塊動畫實例講解

更新時間：2021年12月03日 08:35:22 作者：我的天才女友

在本篇文章里小編給大家整理的是一篇關(guān)于pygame實現(xiàn)方塊動畫實例講解內(nèi)容，以后需要的朋友們可以學(xué)習(xí)參考下。

導(dǎo)入組件

首先導(dǎo)入需要的組件，pygame游戲組件，time是時間組件

import pygame, time, sys
from pygame.locals import *

繪制窗口

這里定義了一個480*600的屏幕，設(shè)置了窗口標(biāo)題，并設(shè)置了屏幕的填充顏色為白色

# 屏幕的寬高
WIDTH = 480
HEIGHT = 600

# 顏色的常量
WHITE = (255, 255, 255)

surface = pygame.display.set_mode((WIDTH, HEIGHT), 0, 30)
pygame.display.set_caption("矩形動畫")

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
    surface.fill(WHITE)


    pygame.display.update()

在這里插入圖片描述

繪制矩形

RED = (255, 0, 0)

# 定義矩形字典變量
rect = {'rect': pygame.Rect(200, 200, 60, 46), 'color': RED}

---
    surface.fill(WHITE)

    pygame.draw.rect(surface,  rect['color'], rect['rect'])
---

讓矩形動起來

從運動來看只有中心向四方移動的四種可能。定義四個方向的常量。
在這里插入圖片描述

# 方向常量
UPLEFT = 'upleft'
UPRIGHT = 'upright'
DOWNLEFT = 'downleft'
DOWNRIGHT = 'downright'

然后定義矩形的移動速度

# 矩形移動的速度
MOVESPEED = 2

給矩形設(shè)置一個初始的移動方向

# 定義矩形字典變量
rect = {'rect': pygame.Rect(200, 200, 60, 46), 'color': RED, 'direction': UPLEFT}

根據(jù)矩形的移動方向改變對應(yīng)的起始位置。根據(jù)矩形不同的位置改變矩形的起始位置。

    # 如果是上左，則x y 都減少
    if rect['direction'] == UPLEFT:
        rect['rect'].left -= MOVESPEED
        rect['rect'].top -= MOVESPEED

    # 如果是上右，則x 增加 y 減少
    if rect['direction'] == UPRIGHT:
        rect['rect'].left += MOVESPEED
        rect['rect'].top -= MOVESPEED

    # 如果是下左，則x 減少 y 增加
    if rect['direction'] == DOWNLEFT:
        rect['rect'].left -= MOVESPEED
        rect['rect'].top += MOVESPEED

    # 如果是下右，則x y 都增加
    if rect['direction'] == DOWNRIGHT:
        rect['rect'].left += MOVESPEED
        rect['rect'].top += MOVESPEED

不斷的改變矩形的位置，要注意防止移出窗口，當(dāng)觸及到邊緣，沿來的方向?qū)⒕匦胃淖兎较蚣纯伞?/p>

    # 如果上溢出窗口
    if rect['rect'].top <= 0:
        if rect['direction'] == UPLEFT:
            rect['direction'] = DOWNLEFT
        if rect['direction'] == UPRIGHT:
            rect['direction'] = DOWNRIGHT

    # 如果下溢出窗口
    if rect['rect'].bottom >= HEIGHT:
        if rect['direction'] == DOWNRIGHT:
            rect['direction'] = UPRIGHT
        if rect['direction'] == DOWNLEFT:
            rect['direction'] = UPLEFT

    # 如果右溢出窗口
    if rect['rect'].right >= WIDTH:
        if rect['direction'] == DOWNRIGHT:
            rect['direction'] = DOWNLEFT
        if rect['direction'] == UPRIGHT:
            rect['direction'] = UPLEFT

    # 如果右溢出窗口
    if rect['rect'].left <= 0:
        if rect['direction'] == DOWNLEFT:
            rect['direction'] = DOWNRIGHT
        if rect['direction'] == UPLEFT:
            rect['direction'] = UPRIGHT

這樣就實現(xiàn)了功能。每次循環(huán)讓時間暫停一會即可。

    # 如果右溢出窗口
    if rect['rect'].left <= 0:
        if rect['direction'] == DOWNLEFT:
            rect['direction'] = DOWNRIGHT
        if rect['direction'] == UPLEFT:
            rect['direction'] = UPRIGHT

    pygame.draw.rect(surface,  rect['color'], rect['rect'])

    pygame.display.update()
    time.sleep(0.02)
