Node keeps disappearing anytime a new game starts

Godot Version



i was making a flappy bird clone and i finished the base game and i wanted to add a score counter that uses numbered images. it works at first, but when i enter a game over? and i try to restart the game by clicking the screen, the texture rect node that is a child of my main node disappears ive seen it disappear when i look at the remote tab of my scene. this also causes alot of errors. so sorry if my formatting is bad, this is my first question posted here

Let me preface this by clearly stating that it’s probably not the best idea to remove and add a bunch of textures every rendered frame.

If this is true, then something either removes the node from the tree or frees it. Both of which does not happen anywhere in the code you shared.

Then it’s usually a good idea to read those… What errors do you get?

Attempt to call function ‘get_children’ in base ‘previously freed’ on a null instance.
this happens at the code

for number in container.get_children():

so uh… i don’t why i’m stupid, i found a weird icon on my score counter node and it turns out i added it to a group called rocks. :smiling_face_with_tear: my obstacle_pair scene actually has it’s own group called rocks so when i used queue free on the rocks group they all disappeared. so sorry and thanks for using your time to try and answer my question. i will close this now.
