我正在使用 PySDL2,并且正在编写一个在 Windows 上加载图像的小脚本,但是当我使用此函数“SDL_QueryTexture”时,我收到此错误消息“ctypes.ArgumentError: argument 4:: expected LP_c_int instance instead of int”。这是我的代码:
"""Simple example for using sdl2 directly."""
import os
import sys
import ctypes
from sdl2 import *
def run():
SDL_Init(SDL_INIT_VIDEO)
window = SDL_CreateWindow(b"Hello World",
SDL_WINDOWPOS_CENTERED,
SDL_WINDOWPOS_CENTERED,
459, 536, SDL_WINDOW_SHOWN)
render = SDL_CreateRenderer(window, -1, 0)
fname = os.path.join(os.path.dirname(os.path.abspath(__file__)),
"resources", "self-control.bmp")
imageSurface = SDL_LoadBMP(fname.encode("utf-8"))
imageTexture = SDL_CreateTextureFromSurface(render, imageSurface)
SDL_FreeSurface(imageSurface)
sourceRectangle = SDL_Rect()
destinationRectangle = SDL_Rect()
SDL_QueryTexture(imageTexture, None, None, sourceRectangle.w, sourceRectangle.h)
destinationRectangle.x = sourceRectangle.x = 0
destinationRectangle.y = sourceRectangle.y = 0
destinationRectangle.w = sourceRectangle.w
destinationRectangle.h = sourceRectangle.h
SDL_RenderCopy(render, imageTexture, sourceRectangle, destinationRectangle)
running = True
event = sdl2.SDL_Event()
while running:
while SDL_PollEvent(ctypes.byref(event)) != 0:
if event.type == sdl2.SDL_QUIT:
running = False
break
SDL_Delay(10)
SDL_DestroyWindow(window)
SDL_Quit()
return 0
if __name__ == "__main__":
sys.exit(run())
我知道与ctypes有关,希望有人可以帮助我。
