I am pretty new to pygame and this is my first basic game code. I am making a platformer game and I have everything rendered, tiles, background, sprite and sprite walking animations. Now I need the physics and I am having a pretty hard time understanding how to go about this. I know you can use rect but from what I see, most youtubers are telling me how to use rect with one sprite image, not multiple. Maybe I could try a different route, what do you guys suggest I do?
import pygame pygame.init() class Player(object): def __init__(self,x,y): self.velocity=4 self.x = x self.y = y self.jumping=False self.right=False self.left=False self.jumptotal=10 self.walkcount=0 self.player_hitbox=(self.x+1,self.y,60,60) def hitbox(self,window): self.player_hitbox = (self.x, self.y, 47, 83) pygame.draw.rect(window,(255,0,0),self.player_hitbox,2) running=True player=Player(20,600) def draw_game(): global player window.blit(background, (0, 0)) if player.walkcount + 1 > 45: player.walkcount = 0 if player.right: window.blit(walk_right[player.walkcount // 3], (player.x, player.y)) player.walkcount += 1 elif player.left: window.blit(walk_left[player.walkcount // 3], (player.x-50, player.y)) player.walkcount += 1 else: window.blit(idle, (player.x, player.y)) player.hitbox(window) for event in pygame.event.get(): if event.type==pygame.QUIT: running=False key_press=pygame.key.get_pressed() if key_press[pygame.K_LEFT] and player.x>player.velocity: player.x-=player.velocity player.right=False player.left=True elif key_press[pygame.K_RIGHT] and player.x<2300-player.x-player.velocity: player.x+=player.velocity player.right = True player.left = False else: player.right=False player.left=False player.walkcount=0 if key_press[pygame.K_UP]: player.jumping=True if player.jumping: if player.jumptotal>=-10: jumpside=1 if player.jumptotal<0: jumpside=-1 player.y-=(player.jumptotal**2)*0.3*jumpside player.jumptotal-=1 else: player.jumping=False player.jumptotal=10 pygame.display.update() pygame.quit() 
elifin your loop that updates your background, It should statistically be faster since it will skip all the other conditions if one is found to be true.
