How to set framerate in Pygame?

Asked 2021-Jun-14 at 04:31

So in response to my question (How to continuously move an image smoothly in Pygame?) I was told to set my framerate in order to do my animation. But no matter where I place it, clock.tick(60) does nothing. I do clock = pygame.time.Clock() BTW. So how do I do this? I have researched and found this (pygame clock.tick() vs framerate in game main loop) but I don't really understand this.

My main game function;

...

ANSWER

Answered 2021-Jun-14 at 04:28

Use pygame.time.Clock to control the frames per second and thus the game speed.

The method tick() of a pygame.time.Clock object, delays the game in that way, that every iteration of the loop consumes the same period of time. See pygame.time.Clock.tick():

This method should be called once per frame.

QUESTION

How to use groupcollide?

Asked 2021-Jun-08 at 16:07

So I've been wondering how to use the pygame groupcollide. And I'm utterly stumped right now. As I am using collide_rect and it is fine. But for groupcollide I can't seem to figure out how to call the properties of the item inside of that group. And I can't do collide rect because there's going to be a lot of bullets.

...

ANSWER

Answered 2021-Jun-08 at 16:07

You cannot use pygame.sprite.groupcollide() here, because the bullets collide with the player that shoots the bullets.
You have to use pygame.sprite.spritecollide(), with one player and the bullets of the opponent. Call it once for each player.

The position of the player is corrected by scroll. You also need to correct the position of the enemies. Remove blob_group.draw(screen) from the redrawGameWindow function, but draw the enemies in a loop:
