将 pygame.Surface() blitting 到 pygame.OPENGL 显示 [英] blitting pygame.Surface() onto pygame.OPENGL display
问题描述
如何将 pygame.Surface() 对象 blit 到 pygame.OPENGL 显示器上并翻转显示器?
How can I blit a pygame.Surface() object onto a pygame.OPENGL display and flip the display?
import pygame
pygame.init()
RES = (640, 480)
display = pygame.display.set_mode(RES, pygame.FULLSCREEN | pygame.OPENGL)
bg_img = pygame.Surface(RES)
bg_img.fill((255, 255, 255))
display.blit(bg_img, (0, 0))
pygame.quit()
sys.exit()
给我
Traceback (most recent call last):
File "C:/Game Dev/TESTS/Clock Comparison/opengl_test.py", line 12, in <module>
display.blit(bg_img, (0, 0))
error: Cannot blit to OPENGL Surfaces (OPENGLBLIT is ok)
推荐答案
你不能.为了避免错误,显示表面需要使用 pygame.OPENGLBLIT
标志而不是 pygame.OPENGL
标志,但是在运行代码之后这个:
You cannot.
To avoid the error, the display surface needs to use the pygame.OPENGLBLIT
flag instead of the pygame.OPENGL
flag, however after running code like this:
import pygame
import sys
pygame.init()
RES = (640, 480)
display = pygame.display.set_mode(RES, pygame.OPENGLBLIT)
bg_img = pygame.Surface(RES).
bg_img.fill((255, 255, 255))
display.blit(bg_img, (0, 0))
pygame.display.flip()
input()
pygame.quit()
sys.exit()
显示窗口保持空白.
pygame 文档将此标志列为:
The pygame documentation lists this flag as:
创建一个 OpenGL 渲染上下文/并将其用于 blitting.过时了.
create an OpenGL rendering context / and use it for blitting. Obsolete.
您需要找到一种方法来代替 pyOpenGL
本身的任何尝试.
You will need to find a way to do whatever you were trying in pyOpenGL
itself instead.
