code not running even without errors

[Azdaghost]

I'm using trinket to run my code but for some reason there is no errors but it's still not running

There is a sytax error on line 28 that prevents the code from running.

1	for event in pygame.event.get();

There is nothing named ground in the program, so this crashes the program first time Obstacle.frame is called:

1	f self.rect.colliderect(ground.rect):

You have to call this function each time you check which keys are pressed. Not just once.

1	keys = pygame.key.get_pressed()

You are still using non-standard indexing. It makes it painful to look at your code in an editor that knows how python is supposed to be formatted. Please change you indent from 2 spaces to 4 spaces.

Obstacle and Player should be pygame sprites. The code will be shorter and the program will run better.

i'm using a trinket editor because I can't download .exe files on a Chromebook (school property)
I don't know how to make it 4 spaces :(
