SDL_RenderCopy（）不適用於數組

-4

我在互聯網上搜索過，在這裏，我發現只有1井後SDL_RenderCopy with an array of Rectangles。有（據我所知）沒有答案，但我的問題是一樣的。有什麼辦法可以做到這一點？SDL_RenderCopy（）不適用於數組

SDL_RenderCopy(renderer, texture, &rects[index], &sprPos);

下面是調試說：

Error 1 error C2664: 'int SDL_RenderCopy(SDL_Renderer *,SDL_Texture *,const SDL_Rect *,const SDL_Rect *)' : cannot convert argument 3 from 'SDL_Rect **' to 'const SDL_Rect *' c:\users\kushnirenko\documents\visual studio 2013\projects\sdl_project\sdl_project\main.cpp 96 1 SDL_Project

_問題尋求調試幫助（「爲什麼不是這個代碼工作嗎？」）必須包括所需的行爲，特定的問題或錯誤以及在問題中重現它的最短代碼本身。沒有明確問題陳述的問題對其他讀者無益。請參閱：如何創建最小，完整和可驗證的示例.'_ –

您的答案甚至不直觀。 OP，你是否從參數3中刪除了＆符號？除非預期有雙指針，否則使用＆符號不是主要的;無論如何，數組通過引用傳遞。 – Poriferous

我解決這個問題。有一種將數組設置爲SDL_RenderCopy的方法。這裏是：

// Sprites atlas regions 
    SDL_Rect left = { sprite * 32, 32, 32, 32 }; 
    SDL_Rect right = { sprite * 32, 64, 32, 32 }; 
    SDL_Rect up = { sprite * 32, 96, 32, 32 }; 
    SDL_Rect down = { sprite * 32, 0, 32, 32 }; 

    SDL_Rect leftIdle = { 32, 32, 32, 32 }; 
    SDL_Rect rightIdle = { 32, 64, 32, 32 }; 
    SDL_Rect upIdle = { 32, 96, 32, 32 }; 
    SDL_Rect downIdle = { 32, 0, 32, 32 }; 
    // End of sprite atlas 

    sprPos = { x, y, 32, 32 }; 

    spritesCoords[0] = left; 
    spritesCoords[1] = right; 
    spritesCoords[2] = up; 
    spritesCoords[3] = down; 

    spritesCoords[4] = leftIdle; 
    spritesCoords[5] = rightIdle; 
    spritesCoords[6] = upIdle; 
    spritesCoords[7] = downIdle; 

    sprFrame = spritesCoords[spriteIndex]; // This is solutuion. 

    SDL_RenderClear(renderer); 
    SDL_RenderCopy(renderer, texture, &sprFrame, &sprPos); 
    SDL_RenderPresent(renderer);
