Ursina 字典中的实体问题 Python

Question

我需要制作一个包含许多单独实体的网格，我正在使用字典自动创建它们，而不是使用 1521 行代码来创建每个单独的实体。

我正在使用 on_click function 来运行 function，“动作”，当实体被点击时，动作 function 需要知道点击了什么实体，所以我为 function 传递了一个参数，告诉它实体的键在存储所有实体的字典中单击。

我的问题是它只给我字典中最后一个键的键，(38,38)

我将如何解决这个问题？

这是我的代码：

def action(button):
    print(button)  # finds what button was clicked


cell_dict = {}
cell_names = []


def create_dicts():
    # Create the keys for each entity. The keys are the entity's coordinates on the board.
    row_num = 0
    for row in board:
        column_num = 0
        for cell in row:
            cell_names.append((row_num, column_num))
            column_num += 1
        row_num += 1

    # Creates entities for each key in the list and adds them to the dictionary.
    for v in range(len(cell_names)):
        cell_dict[cell_names[v]] = Entity(model='quad', color=color.red, scale=0.125, collider='box', on_click=lambda: action(cell_names[v]))

Answer 1

尝试将 lambda 更改为 function：

def action(button):
    print(button)  # finds what button was clicked


cell_dict = {}
cell_names = []


def create_dicts():
    # Create the keys for each entity. The keys are the entity's coordinates on the board.
    row_num = 0
    for row in board:
        column_num = 0
        for cell in row:
            cell_names.append((row_num, column_num))
            column_num += 1
        row_num += 1

    # Creates entities for each key in the list and adds them to the dictionary.
    for v in range(len(cell_names)):
        cell_dict[cell_names[v]] = Entity(
            model="quad",
            color=color.red,
            scale=0.125,
            collider="box",
            on_click=lambda name=cell_names[v]: action(name),  # <-- create a parameter here
        )
