以下是一个基本的贪吃蛇游戏示例,使用 Panda3D 游戏引擎进行渲染:
```python
from direct.showbase.ShowBase import ShowBase
from direct.task import Task
from direct.gui.OnscreenText import OnscreenText
from panda3d.core import TextNode
from panda3d.core import Point3, Vec3
from random import randint
class Snake(ShowBase):
def __init__(self):
ShowBase.__init__(self)
# 设置摄像机位置
self.camera.setPos(0, -30, 6)
# 定义游戏区域边界
self.boundaries = {
'x_min': -10,
'x_max': 10,
'y_min': -10,
'y_max': 10
}
# 定义贪吃蛇和食物的属性
self.snake = []
self.food = None
self.score = 0
# 设置游戏文字
self.font = loader.loadFont("fonts/Roboto-Bold.ttf")
self.title_text = OnscreenText(text="Snake Game",
pos=(0, 0.9),
scale=0.1,
fg=(1, 1, 1, 1),
align=TextNode.ACenter,
font=self.font)
self.score_text = OnscreenText(text="Score: {}".format(self.score),
pos=(-1.3, 0.9),
scale=0.1,
fg=(1, 1, 1, 1),
align=TextNode.ALeft,
font=self.font)
# 开始游戏
self.setup_game()
def setup_game(self):
# 初始化贪吃蛇
self.snake = [self.add_cube(0, 0, 0)]
self.direction = Vec3(0, 1, 0)
# 添加食物
self.add_food()
# 设置游戏循环
self.taskMgr.add(self.move_snake, "MoveSnake")
def add_cube(self, x, y, z):
# 定义方块的大小和颜色
size = 0.8
color = (randint(0, 255) / 255.0, randint(0, 255) / 255.0, randint(0, 255) / 255.0)
# 创建方块对象
cube = self.loader.loadModel("models/box")
cube.setScale(size, size, size)
cube.setColor(color[0], color[1], color[2], 1)
cube.setPos(Point3(x, y, z))
# 将方块添加到场景中
cube.reparentTo(self.render)
return cube
def add_food(self):
# 随机生成食物位置
x = randint(self.boundaries['x_min'], self.boundaries['x_max'])
y = randint(self.boundaries['y_min'], self.boundaries['y_max'])
z = 0
# 检查食物是否与贪吃蛇重叠
while self.check_overlap(x, y):
x = randint(self.boundaries['x_min'], self.boundaries['x_max'])
y = randint(self.boundaries['y_min'], self.boundaries['y_max'])
# 添加食物
self.food = self.add_cube(x, y, z)
def move_snake(self, task):
# 获取贪吃蛇头部位置
head_pos = self.snake[0].getPos()
# 计算下一步的位置
next_pos = head_pos + self.direction
# 检查是否撞墙
if next_pos.getX() < self.boundaries['x_min'] or next_pos.getX() > self.boundaries['x_max'] or next_pos.getY() < self.boundaries['y_min'] or next_pos.getY() > self.boundaries['y_max']:
self.game_over()
# 检查是否吃到食物
if self.check_overlap(next_pos.getX(), next_pos.getY()):
self.score += 1
self.score_text.setText("Score: {}".format(self.score))
self.add_food()
else:
# 移动贪吃蛇尾部
tail = self.snake.pop()
tail.setPos(head_pos)
self.snake = [tail] + self.snake
# 移动贪吃蛇头部
self.snake[0].setPos(next_pos)
return Task.cont
def check_overlap(self, x, y):
# 检查贪吃蛇是否与食物重叠
if self.food.getPos().getX() == x and self.food.getPos().getY() == y:
return True
# 检查贪吃蛇是否与自己重叠
for cube in self.snake:
if cube.getPos().getX() == x and cube.getPos().getY() == y:
return True
return False
def game_over(self):
# 游戏结束
self.title_text.setText("Game Over")
self.taskMgr.remove("MoveSnake")
if __name__ == "__main__":
game = Snake()
game.run()
```
在这个示例中,我们使用了 Panda3D 的基本功能,如场景图、模型加载、键盘输入处理和任务管理。我们还使用了 Python 的基本数据结构,如列表和字典。这个示例只是一个简单的贪吃蛇游戏,你可以根据自己的需要进行扩展和优化。
