昨天，我问了一个有关我遇到的问题的问题：Create Entities Reduce FPS And Overlapping。通过以下逻辑，我设法解决了FPS下降的问题：
结果，实体创建功能已简化为：
def create_entity(self, pos_x, pos_y, obj):
if obj not in self.main.model.model_enemy:
entity = self.main.model.model_enemy["0000"]
else:
entity = self.main.model.model_enemy[obj]
entity["battle"]["position"] = (pos_x, pos_y)
entity["battle"]["sprite"][entity["battle"]["state"]][entity["battle"]["direction"]].x = pos_x
entity["battle"]["sprite"][entity["battle"]["state"]][entity["battle"]["direction"]].y = pos_y
return entity
该函数被调用，并为其提供参数：pos_x，pos_y（绘制实体的位置）和obj（为实体选择的模型）。 if语句检查请求的模板是否存在于self.main.model.model_enemy中（它包含所有模型）。如果不存在，则为其分配基本模型。下一部分是位置的简单设置。完成后，将返回创建的实体。
我遇到的问题是，如果我编辑以这种方式创建的任何实体的属性（创建时将每个实体放置在列表中），那么我将为所有实体进行编辑。
我认为这是发生的，因为当我将模型类型分配给实体（entity = self.main.model.model_enemy）时，实际上并没有创建该模型的副本。因此，要更改实体的属性，实际上是要更改模型的属性。结果，将修改使用该模型创建的所有实体。相反，我需要复制模型，以使其与模型保持独立。这样，我可以修改实体的属性，而无需修改模型本身。
我已经尝试使用：copy.deepcopy，但是它不起作用，因为它给我错误。你能给我什么建议？我遇到的问题是Python，这就是为什么没有Pyglet标签的原因。
我为您提供了一个基本模型，以便您可以了解它的组成方式（该模型仍然缺少将来必须添加的部分）：
