当我的角色的碰撞框与某个 NPC 的碰撞框发生碰撞时，我在屏幕上显示文本框时遇到问题。
第一部分代码是我创建的模块文件的一部分，我在其中创建了供游戏使用的 Assets 。这是我创建要在主文件中使用的文本框对象的地方。
import pygame, sys
from pygame.locals import *
class stuff:
def __init__(self, Surface):
self.surface = Surface
self.readyfornextbox = False
self.textboxlist = []
def textbox(self, textinput, textcolor,location): #extra is basically asking whether or not the programmer wants t oclose
self.readyfornextbox = True #Checks if player is going to be clicking for next text box to appear on screen
self.font = pygame.font.Font(None, 24)
text = self.font.render(textinput, 1, (255, 0, 0))
self.textboxlist.append([text,location])
def ready(self, ready):
if self.textboxlist:
self.textboxlist.remove(self.textboxlist[0])
if(not self.textboxlist):
self.readyfornextbox=False
def draw_textbox(self):
if(self.readyfornextbox==True):
pygame.draw.rect(self.surface, (0, 255,0), self.textboxlist[0][1])
self.surface.blit(self.textboxlist[0][0], ((self.textboxlist[0][1].x + 25), (self.textboxlist[0][1].y + 25)))
下一段代码来自游戏本身的主文件。当玩家的碰撞盒与 NPC 的碰撞盒发生碰撞的条件满足时，我会调用此方法将文本框绘制到屏幕上。我在主游戏循环之外调用它。
if PC_ColBox.colliderect(OM_ColBox):
blah.textbox("Hello there, young man", (255, 0, 0), bottom)
由于某种原因，文本框没有显示在屏幕上。我之前曾使用相同的条件语句毫无问题地在玩家和 NPC 之间创建边界，以阻止玩家与 NPC 重叠。所以我不认为条件是问题所在。此外，当文本框在没有条件语句的情况下单独调用时，它显示得很好。
提前感谢您的帮助。
编辑 根据两个用户的要求，我将在下面粘贴整个主文件的代码。非常感谢你们尝试提供帮助:)

编辑 2 根据 Junuxx 的建议，我将在主循环内调用文本框的条件放在 PC 与 NPC 碰撞时移开之前。如下所示。不幸的是，即使这样安排，文本框仍然没有显示。
if PC_ColBox.colliderect(OM_ColBox):
blah.textbox("Hello there, young man", (255, 0, 0), bottom)
if RIGHT == True:
PC_ColBox.x += Change
if PC_ColBox.colliderect(OM_ColBox):
PC_ColBox.x -= Change
if LEFT == True:
PC_ColBox.x -= Change
if PC_ColBox.colliderect(OM_ColBox):
PC_ColBox.x += Change
最佳答案
你真的打电话pygame.display.update()吗？位图文本框之后？这是需要在屏幕上显示任何更改的!
编辑: 在查看更多代码后，看来您应该将碰撞检测移到主循环内。现在，您只需在进入主循环之前开始检查一次碰撞。
当然，考虑到他们的起始位置，两个角色在开始移动之前不可能发生碰撞。
如果将其移到 if RIGHT == True 条件之前，应该可以工作。
if PC_ColBox.colliderect(OM_ColBox):
blah.textbox("Hello there, young man", (255, 0, 0), bottom)
if RIGHT == True:
PC_ColBox.x += Change
if PC_ColBox.colliderect(OM_ColBox):
PC_ColBox.x -= Change
