So i'm fairly new to Pygame and python in general and so i'm trying to make my first game from purely my own code, not fallowing a tutorial or anything and I'm encountering an issue that I just can't find the solution to, I'm using a placeholder ducky png as the 'obstacle' for the player to jump over and all the sprite needs to do is spawn just out of screen an travel from the right to the left side, which I actually have working. but when ever a new sprite is spawned in while another is on the screen is just disappears (I'll try and include a clip of the game running as an example). help please
