I would have two questions to propose. In the project I am working on, I have created a class that deals with all the entities (enemies) that are created. This is the class (if you need anything else, tell me):

class entity():

 def __init__(self, main):
 self.main = main
 self.main.update_list.append(self.update)
 self.main.draw_list.append(self.on_draw)

 self.entity_spawn = 
 self.ent_made = False

 def create_entity(self, pos_x, pos_y, obj):
 data = libraries.pokémon_data(obj)
 entity = OrderedDict()
 image = self.__resource(obj, "img")
 entity["name"] = obj
 entity["tile"] = 0
 entity["image"] = OrderedDict()
 entity["texture"] = OrderedDict()
 entity["sprite"] = OrderedDict()
 for obj, item in data["img"]["battle"].items():
 entity["tile"] = item["tile"]
 entity["image"][obj] = OrderedDict()
 entity["texture"][obj] = OrderedDict()
 entity["sprite"][obj] = OrderedDict()
 id = 0
 for idy in range(len(item["y"])):
 y = item["tile"] * item["y"][idy]
 list_frame_img = 
 list_frame_texture = 
 for idx in range(len(item["x"])):
 x = item["tile"] * item["x"][idx]
 frame = image.get_region(x=x, y=y, width=item["tile"], height=item["tile"])
 list_frame_img.append(frame)
 texture = frame.get_texture()
 gl.glTexParameteri(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MAG_FILTER, gl.GL_NEAREST)
 if self.main.dimension != self.main.min:
 tile = self.__tiles(48)
 else:
 tile = 48
 texture.width = tile
 texture.height = tile
 texture.anchor_x = texture.width // 2
 texture.anchor_y = texture.height // 2
 list_frame_texture.append(texture)
 if len(list_frame_img) > 1:
 entity["image"][obj][id] = pyglet.image.Animation.from_image_sequence(list_frame_img, 0.5, True)
 else:
 entity["image"][obj][id] = list_frame_img[0]
 if len(list_frame_texture) > 1:
 entity["texture"][obj][id] = pyglet.image.Animation.from_image_sequence(list_frame_texture, 0.5, True)
 else:
 entity["texture"][obj][id] = list_frame_texture[0]
 entity["sprite"][obj][id] = pyglet.sprite.Sprite(entity["texture"][obj][id])
 entity["sprite"][obj][id].x = pos_x
 entity["sprite"][obj][id].y = pos_y
 id += 1
 return entity

 def __tiles(self, obj):
 list = [self.main.min, self.main.max]
 res = 
 for i in range(len(list)):
 x = list[i][0]
 y = list[i][1]
 ds = (x - y) / (y / 100)
 dk = (obj / 100) * ds
 tile = obj + int(dk)
 res.append(tile)
 if (res[0] % res[1]) == 0:
 return res[0]
 else:
 return max(res[0], res[1])

 def __resource(self, obj, type):
 res = type + obj
 if res in resources[type]:
 return resources[type][type+obj][1]
 else:
 self.__error(res)
 return resources[type][type+"0000"][1]

 def __error(self, obj):
 date = datetime.datetime.now()
 self.main.error_engine.append([date.strftime("%d-%m-%Y %H:%M:%S"), obj + " missing"])

 def on_draw(self):
 for entity in self.entity_spawn:
 entity["sprite"]["idle"][0].draw()

 def update(self):
 if self.ent_made:
 if len(self.entity_spawn) < 10:
 x = random.randint(50, self.main.dimension[0] - 50)
 y = random.randint(50, self.main.dimension[1] - 50)
 entity = self.create_entity(x, y, "0001")
 self.entity_spawn.append(entity)

First question: When, with the main class, I change the status of self.ent_made (from False to True), the FPS from 60 drops drastically to 4. I assume that the entity creation function eats too much RAM, so how can I improve it to avoid this drastic drop in FPS?

Second question: how can I generate the entities, so that they are not superimposed on each other?

Here is a demonstration of what happens. The FPS are at 40 simply because I was recording, otherwise I am at 60. Moreover, for the second question, it happens above all when the created entities are many. With 10 (limit put only to test at the time) it is difficult to happen:
