Question

使用Raycast函数显示图像时，我无法使python工作，该如何解决？

我尝试移动一些变量并使用该函数，但是似乎无法正常工作。

import pygame
pygame.init()

Screen = "Title"
DB = 0
Width = 800
Height = 600

Frame = pygame.display.set_mode((Width,Height))
pygame.display.set_caption("GAME")
FPS = pygame.time.Clock()

def Raycast(RayXPos, RayYPos):
    RaycastThis = pygame.image.load(TTR)
    Frame.blit(RaycastThis, (RayXPos, RayYPos))
    Loop = True
    while Loop == True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                exit()
    pygame.display.update()

    FPS.tick(60)

    while Screen == "Title" and DB == 0:
        TTR = 'TitleScreenSmall.png'
        Raycast(0, 0)

我希望框架显示图像（与窗口大小相同），但它崩溃了，并且我无法运行程序

您的问题是无限循环：

<button id="button" type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="Add a recipe">Add a recipe</button>
<!-- end of button -->

<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">

          </div>

        </form>
      </div>
    </div>
  </div>
</div>

由于循环控制变量while Screen == "Title" and DB == 0: TTR = 'TitleScreenSmall.png' Raycast(0, 0)和Screen永不改变，因此您无法退出循环。您被困在这里，永远重复执行一项功能，几乎没有任何变化，并且无需观察任何变化。
