为什么我的碰撞类型和 y 速度的更新速度不够快？

问题描述

我已经对它进行了编码，以便当我跳跃时我的播放器类的底部碰撞应该为真，并且当我与地板碰撞时它将被设置为真，并且我在更新开始时将碰撞类型重置为假功能。但是为什么底部碰撞类型不保持为真，有时会变为假。谢谢！

ObjectHandler 文件：

import pygame
from dev.nils.pythonGame.game.objects.tile import *
from dev.nils.pythonGame.game.objects.player import *
from dev.nils.pythonGame.framework.physicsObject import *
from dev.nils.pythonGame.game.objects.enemy import *


class Handler:
    def __init__(self,path: str,screen: pygame.Surface,screen_size:()):
        self.path = path
        self.objects = {
            "player":Player(0,16,32)
        }
        self.screen = screen
        self.tileList = self.getTileList()
        self.screen_size = screen_size

        self.enemyHandler = EnemyHandler()

    def update(self):
        for object in self.objects.values():
            self.enemyHandler.update(self.tileList,self.getCollisionList,self.objects["player"])
            object.update(self.tileList,self.screen_size)

def getTileList(self):
        tiles = []
        x = 0
        y = 0
        with open(self.path) as map:
            map = list(map)
            for row in map:
                x = 0
                for tile in row:
                    if tile != "0":
                        tiles.append([tile,PhysicsObject(x,16)])
                    x += 1
                y += 1
        return tiles

    def getCollisionList(self,tileList:[]):
        collisions = []
        for tile in tileList:
            if objectRect.colliderect(tile[1].rect):
                collisions.append(tile)
        return collisions

我想要它以便我可以使用collisionTypes字典来检查碰撞是否真的是真的，我认为它与physicsObject类中的collisions2D函数有关，我将yVel变量设置为0并将底部变量设置为碰撞类型列表为真
