我在尝试声明标识符时遇到了问题。主要部分是textureBackground.loadFromFile(“graphics / background.png”);其中textureBackground是带下划线的那个
我尝试添加括号,更改大写,小写,检查文件位置等。
int main()
{
//Create a video mode object
VideoMode vm(1920, 1080);
// Create and open a window for game
RenderWindow window(vm, "Scarful!!!", Style::Fullscreen);
while (window.isOpen())
// Texture for graphic on cpu
Texture textureBackground;
// Load graphic into texture
textureBackground.loadFromFile("graphics/background.png");
// Make Sprite
Sprite spriteBackground;
// Attach texture to sprite
spriteBackground.setTexture(textureBackground);
// Set spritebackground to cover screen
spriteBackground.setPosition(0, 0);
{
/* Handle player input */
if (Keyboard::isKeyPressed(Keyboard::Escape))
{
window.close();
}
//Update Scene
//Draw Scene
window.clear();
//Draw Game Scene
window.draw(spriteBackground);
//Show everything we drew
window.display();
}
return 0;
}
这里,
while (window.isOpen())
// Texture for graphic on cpu
Texture textureBackground;
// Load graphic into texture
textureBackground.loadFromFile("graphics/background.png");
你正试图这样做:
while (window.isOpen()) {
// Variable goes out of scope outside of the loop...
Texture textureBackground;
}
textureBackground.loadFromFile("graphics/background.png");
// ^^^^^^^^^^^^^^^^^ is not available anymore...
由于textureBackground
超出范围,你不能再修改它...我建议你想...
// Texture for graphic on cpu
Texture textureBackground;
// Load graphic into texture
textureBackground.loadFromFile("graphics/background.png");
// Make Sprite
Sprite spriteBackground;
// Attach texture to sprite
spriteBackground.setTexture(textureBackground);
// Set spritebackground to cover screen
spriteBackground.setPosition(0, 0);
while (window.isOpen()) {
// Other code goes here...
}
