废话多说
以下是一个基于Python和ModernGL的简化版3D沙盒游戏框架。由于代码长度限制，这里提供一个核心实现（约500行），您可以通过添加更多功能和内容来扩展它：
```python
import pygame
import moderngl
import numpy as np
import glm
import random
import time
import sys
from pygame.locals import *
from PIL import Image
# 常量设置
SCREEN_SIZE = (1280, 720)

WORLD_SIZE = 4
GRAVITY = 0.05
JUMP_FORCE = 1.5

2: {"name": "dirt", "texture": (1, 0)},
3: {"name": "stone", "texture": (2, 0)},
}

def generate_chunk(self, cx, cz):

for x in range(CHUNK_SIZE):

for y in range(height):
if y == height-1:
chunk_data[x,y,z] = 1
elif y >= height-4:
chunk_data[x,y,z] = 2
else:

self.chunks[(cx, cz)] = chunk_data
