Python Turtle模块如何批量自动生成独立RawTurtle对象

• 需求：传入数量参数a，批量生成属性统一的RawTurtle游戏实体，每个实体有独立标识支持单独调用，同时支持统一遍历操作

初始试错代码 #

def spawnEntity(a):
    for x in range(0, a):
        global entity
        spawnpt = (rand.randrange(-(cWidth/2), cWidth/2), rand.randrange(-(cHeight/2), cHeight/2))
        entName = (f'entity{x}')
        def entGenerate(a):
            print(a)
            (f'{a}') = turtle.RawTurtle(screen)
            (f'{a}').shape("square")
            (f'{a}').speed("fastest")
            (f'{a}').penup()
            (f'{a}').pencolor("gray")
            (f'{a}').fillcolor("gray")
            (f'{a}').setpos(spawnpt)
            print(a)
        entGenerate(entName)
        entList = []
        entList.append(entName)

proportion = (16, 9)
cWidth = (proportion[0] * 80)
cHeight = (proportion[1] * 80)

root = Tk()
root.title("Shooter Game")

canvas = Canvas(master=root, width=cWidth, height=cHeight)
canvas.grid(row=1, column=1)
screen = turtle.TurtleScreen(canvas)
    
spawnEntity(4)
    
root.mainloop()

可运行的最终实现 #

def spawnEntity(a):
    global ent, entity
    ent = (a)
    entity = {num: turtle.RawTurtle(screen) for num in range(ent)}
    for i in range(ent):
        spawnpt = (rand.randrange(-(cWidth/2.5), cWidth/2.5), rand.randrange(-(cHeight/2.5), cHeight/2.5))
        entity[i].shape("square")
        entity[i].speed("fastest")
        entity[i].penup()
        entity[i].pencolor("gray")
        entity[i].fillcolor("gray")
        entity[i].setpos(spawnpt)

• 单独调用某实体：通过序号字典键取值，例如操作第2个实体移动可写entity[2].forward(50)
• 批量操作所有实体：遍历字典值实现统一逻辑，例如

for turtle_obj in entity.values():
    turtle_obj.setx(0)
