При стрельбе из пули стреляет в мишень

/ 04 марта 2020

Я программирую небольшую игру, которая является шутером для школьного проекта. Если вы запустите игру, вы заметите, что цели уже двигаются с заиканием, но затем, когда вы начинаете стрелять, это становится неиграбельным. Это только что предлагает pygame с частотой кадров или это можно исправить в коде? 




pygame.init()
window = pygame.display.set_mode((800, 575))
pygame.display.set_caption("TARGET PRACTICE")
