I am in troubles, I am trying to make doors opening in my game. I am using pygame, and pytmx, I have built a Level made with Rooms, and in each Room I have a Renderer using pytmx, what I want to achieve is for exemple on level 0 the player has to move to a door to open it and enter level 1, my goal is to launch and draw the animation when player hit the door.
I tried to make my Door object (his parent is pygame Sprite class) update, it has kind of worked but of course the object was modified and displayed, but the tiled map object also and was staying in the back of the map, so I tried to just not initialize my objects in the tile map but if so the door doesn't bit at all. Then I tried to modify the tile object image and to reload my rendering but still doesn't work, does anyone of you has any idea ?
Here is some parts of the code to let you have better understanding

So right now what I am trying to do is to use an animated tile object and launch the animation from tmx data, but I can't even understand how to launch the animation at the first rendering.
Thank you in advance for you answers.
So I found a solution, I am not trying to change and reload the object tiles, I simply made my game sprites in groups, modified my generating and rendering of tiles.

def update(self):
self.all_sprites.update()
def draw(self):
self.window.fill((0, 0, 0))
## DISPLAY MAP
self.level.draw_room(self.window, self.camera)
## DISPLAY SPRITES
for sprite in self.all_sprites:
self.window.blit(sprite.image, (sprite.rect.x - self.camera.offset.x, sprite.rect.y - self.camera.offset.y))
## REFRESH SCREEN
pygame.display.flip()
And here is the result (I am working on better hitbox for the player ^^) door opening when player getting close to it
