从Sprite表Java读取图像 [英] Reading images from a sprite sheet Java

问题描述

我想在游戏中使用精灵表，经过研究，我发现了这段代码.

I want to use sprite sheets in my game and with the research I have done found this piece of code.

    BufferedImage bigImg = ImageIO.read(new File("sheet.png")); 
// The above line throws an checked IOException which must be caught. 

final int width = 10; 
final int height = 10; 
final int rows = 5; 
final int cols = 5; 
BufferedImage[] sprites = new BufferedImage[rows * cols]; 

for (int i = 0; i < rows; i++) 
{ 
    for (int j = 0; j < cols; j++) 
    { 
        sprites[(i * cols) + j] = bigImg.getSubimage( 
            i * width, 
            j * height, 
            width, 
            height 
        ); 
    } 
} 

我了解此片段如何将精灵表转换为数组，但是我如何访问该数组.只是sprites[i];吗?

I understand how this snippet will turn the sprite sheet into an array, but how do I access this array. Is it just sprites[i]; ?

还可以使用

int spritename = glgentextures;
{
sprites[i];
}

提前谢谢.

推荐答案

要访问sheet.png中的特定图像，可以使用sprite [rowNum * cols + colNum].

To access a certain image in sheet.png you can use sprite[rowNum*cols + colNum].
