Question

当我的角色的碰撞盒与某个NPC的碰撞盒碰撞时，我在向屏幕显示文本框时遇到问题。

这段代码的第一部分是我创建的模块文件的一部分，我创建的资源供游戏使用。这是我创建我的文本框对象以在主文件中使用的地方。

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)))

下一部分代码来自游戏本身的主文件。这是我在调用播放器的碰撞盒碰撞NPC碰撞盒的条件时将文本框绘制到屏幕的地方。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，文本框未显示在屏幕上。我之前使用相同的条件语句没有问题，在玩家和NPC之间创建一个边界，阻止玩家重叠到NPC上。所以我认为条件不是问题所在。此外，当文本框自身被调用而没有条件语句时，它显示就好了。

提前感谢您的帮助。

修改根据两个用户的要求，我将粘贴下面的整个主要代码文件。非常感谢你们帮助我们寻求帮助：）

编辑2 正如Junuxx所建议的那样，我把主要循环中的文本框调用条件放在条件之前，如果它与NPC发生冲突，我会让PC离开。如下所示。遗憾的是，即使有这样的安排，文本框仍然没有出现。

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

Answer 1

在blot文本框后，你真的打电话给pygame.display.update()吗？这需要显示屏幕的任何更改！

修改看到更多代码后，您似乎应该在主循环中移动碰撞检测。现在你只检查一次碰撞，就在开始之前进入主循环。

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。

如果您在if RIGHT == True条件之前将其移至右侧，则应该有效。

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

当角色与NPC发生碰撞时显示文本框时出现问题
