什么是相对于图像序列的精灵表的利弊？ [英] What are the pros and cons of a sprite sheet compared to an image sequence?

问题描述

我来自一个2D动画的背景，所以当我过我们的动画序列我preFER使用图像序列。对我来说，这使得有很大的意义，因为你可以轻松地从合成/编辑软件导出图像序列轻易地定义方面。

I come from a 2D animation background and so when ever I us an animated sequence I prefer to use a sequence of images. To me this makes a lot of sense because you can easily export the image sequence from your compositing/editing software and easily define the aspect.

我是新游戏开发和好奇的使用精灵表的。有什么优点和缺点。是文件大小的问题吗？ - 对我来说，似乎说了一堆小图片将是相同的一台庞大的之一。此外，定义精灵的各个领域似乎时间很麻烦。

I am new to game development and am curious about the use of a sprite sheet. What are the advantages and disadvantages. Is file size an issue? - to me it would seem that a bunch of small images would be the same as one massive one. Also, defining each individual area of the sprites seems time cumbersome.

基本上，我不明白你为什么会使用一个精灵表 - 请赐教

Basically, I dont get why you would use a sprite sheet - please enlighten me.

感谢

推荐答案

性能是精灵表更好，因为你必须包含在一个单一的纹理所有数据。比方说你有1000个精灵从精灵表玩同样的动画。绘制过程会去像。

Performance is better for sprite sheets because you have all your data contained in a single texture. Lets say you have 1000 sprites playing the same animation from a sprite sheet. The process for drawing would go something like.

Set the sprite sheet texture.
Adjust UV's to show single frame of animation.
Draw sprite 0
Adjust UV's
Draw sprite 1
.
.
.
Adjust UV's
Draw sprite 998
Adjust UV's
Draw sprite 999

使用纹理序列可能导致的最坏的情况：

Using a texture sequence could result in a worst case of:

Set the animation texture.
Draw sprite 0
Set the new animation texture.
Draw sprite 1
.
.
.
Set the new animation texture.
Draw sprite 998
Set the new animation texture.
Draw sprite 999

尔加！绘制之前每一个角色，你就必须设置渲染状态下使用不同的纹理，这是的慢得多的不是调整一对夫妇紫外线的的。

Gah! Before drawing every sprite you would have to set the render state to use a different texture and this is much slower than adjusting a couple of UV's.
