我一直在试用 SDL 2,但遇到了 SDL_Rect does not name a type
错误...
代码:
#include <stdio.h>
#include <SDL.h>
using namespace std;
SDL_Window* gWindow = NULL;
SDL_Surface* gWSurface = NULL;
SDL_Surface* gFinalImage = NULL;
int screenW = 640;
int screenH = 480;
SDL_Rect stretchRect;
stretchRect.x = stretchRect.y = 0;
stretchRect.w = screenW;
stretchRect.h = screenH;
错误日志:
||=== Build: Debug in SDLEvents (compiler: GNU GCC Compiler) ===|

D:\My Works\SDL Stretching\TestingSDL.cpp|13|error: 'stretchRect' does not name a type|

我已经在线检查过这里的另一个问题,但到目前为止还没有解决问题...... 谢谢大家
最佳答案
如果我正确理解你显示的代码,你会尝试在全局范围内,在任何函数之外对矩形进行初始化。你这样做是不可能的,你不能在函数之外有赋值语句。
有两种解决方法:
在声明中初始化,如
SDL_Rect stretchRect = { values... };
在全局范围内声明变量,并在函数中初始化:
SDL_Rect stretchRect; ... int main() { stretchRect.x = stretchRect.y = 0; stretchRect.w = screenW; stretchRect.h = screenH; ...
关于c++ - SDL_rect 没有命名类型,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/24990793/
