Use Node structures to manage Pygame resources for rapid game creation and management.
Project description
PygameNode
使用 Node 结构管理Pygame资源, 以便快速制作/管理游戏.
还未开发完成
1. 快速开始
使用 pip install pygame_node 安装这个库.
接着导入库并写一个简单的示例
# 导入 pygame 和 pygame_node 库
import pygame
from pygame_node import *
# 定义作为屏幕大小的变量
SCREEN_WIDTH, SCREEN_HEIGHT = 1200, 700
# 创建一个场景
class MainScene(BaseScene):
def __init__(self):
# 初始化场景, 名称为Main
super().__init__("Main")
# pygame 初始化
pygame.init()
# 创建场景管理器, 把场景传入创建管理器里
main_scene = MainScene()
manager = SceneManager(main_scene)
# 创建屏幕对象和时钟对象
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT), pygame.HWSURFACE | pygame.DOUBLEBUF, vsync=True)
clock = pygame.time.Clock()
# 切换到 Main 场景
manager.switch("Main")
# 创建运行状态变量
running = True
while running:
# 获取事件
events = pygame.event.get()
for event in events:
# 程序退出
if event.type == pygame.QUIT:
running = False
break
# 场景处理事件
manager.events(events)
# 场景更新
manager.update(clock.tick(0) / 1000.0)
# 绘制场景
manager.draw(screen)
pygame.display.flip()
pygame.quit()
1.1 场景
可在场景对象里添加初始化函数
from pygame_node import *
from pygame.math import Vector3
class MainScene(BaseScene):
def __init__(self):
super().__init__("Main")
# 定义初始化函数
def init(self, params: 'BaseScene' = None):
super().init(params)
# 创建一个文本 "It's a Text Node." 的 TextNode
# 位置在Vector3(200, 200, 0)
text = TextNode("It's a Text Node.", position=Vector3(200, 200, 0), font=Font(size=72))
# 添加到场景中
self.addNode(text)
font 参数如果在 pygame.init()后定义了全局字体就可以不传
import pygame
from pygame_node import *
pygame.init()
Node.font = Font(size=72) # 定义全局字体默认字体
运行后文字和背景是一个色的, 所以要修改背景色或文字颜色后才能看到.
# 在MainScene中添加, 修改背景色为绿色
def draw(self, screen: Surface):
screen.fill((0x84, 0xC6, 0x69))
super().draw(screen)
文字颜色可以通过以下代码更改
# 修改文本颜色为白色
text.style.color = Color(255, 255, 255)
可以通过设置文字的 style 不同值达到不同效果
text.style.shadow.enable = True # 启用影子
text.style.shadow.color = Color(64, 128, 255) # 修改影子颜色
text.style.stroke.enable = True # 启用边缘
text.style.stroke.size = 0.5 # 修改边缘大小
文本样式不止这些, 详情.不同效果可以同时使用
