Character moving with keyboard inputs without actually moving on screen

So i have a problem where my character is drawn at the first frame and i am able to move and collect "ammo" with it but my character is invisible and i have no idea why it is happening. Also tried to change something from Vector to rect but it does not works.

import pygame
from sys import exit
from pygame.math import Vector2
import random

pygame.init()
win = pygame.display.set_mode((800,600))
pygame.display.set_caption("Rectshooter")
clock = pygame.time.Clock()
game_active = True


class Player :
    width = height = 50

    def __init__(self,color=(255,0,0)):
        self.body = Vector2(500,200)
        self.color = color
        self.direction = Vector2(0,0)
        self.player_rect = pygame.Rect(self.body.x,self.body.y,self.width,self.height)



    def draw(self):
        #pygame.draw.rect(win,self.color,(self.body.x,self.body.y,self.width,self.height))
        pygame.draw.rect(win, self.color, self.player_rect)

    def move(self):
        self.body += self.direction

class Player2 :
    width = height = 50

    def __init__(self,color=(255,0,0)):
        self.body = Vector2(300,200)
        self.color = color
        self.direction = Vector2(0,0)




    def draw(self):
        pygame.draw.rect(win,self.color,(self.body.x,self.body.y,self.width,self.height))

    def move(self):
        self.body += self.direction

class Ammo:
    width = height = 30

    def __init__(self,x1,x2):
        self.x = random.randint(x1,x2)
        self.y = random.randint(50,550)
        self.pos = Vector2(self.x,self.y)
        self.ammo_rect = pygame.Rect(self.x,self.y,self.width,self.height)

    def draw_ammo(self):
        pygame.draw.ellipse(win,(255,100,00),self.ammo_rect)









player1 = Player()
player2 = Player2()
speed = 15 #player speed
ammo1 = Ammo(50,300)
ammo2 = Ammo(450,750)
print(ammo2.pos.x)
print(player1.body.x)

There is another problem with colliding, i wrote a long if statement for it and it works fine,but i want to make it with simple "player1.player_rect.colliderect(ammo2.ammo_rect)" if statement,but this only triggers when the ammo(random spawn) spwans at the location of the player,i mean the original location of the player that spawns at the first frame not the current location. I am so confused,and i need a little help with it.
