I'm trying my best to make a dino game replica and I'm stuck at increasing the speed of the obstacles that comes towards the character. The speed of 5 just seems to be the magic number but when I change it to six the rock doesn't get detected and ultimately doesn't spawn the next rock.
I don't know why.
there are no errors except for when the rock doesn't get spawned and I get an index out of range:
Traceback (most recent call last):
File "C:\Users\austi\OneDrive\Desktop\scroller game\main.py", line 109, in <module>
main()

if game.collide():
File "C:\Users\austi\OneDrive\Desktop\scroller game\main.py", line 71, in collide
olh = self.obstacles[0].hitBox[0]
IndexError: list index out of range
here is what I got:

and I suspect the issue is in the spawn function in the Game class in main.py
I've been trying to work on this for a couple days now and I still cannot solve my issue.
