在Unity中创建和渲染大量2d精灵的最快方法是什么? [英] What is the fastest method to create and render large number of 2d sprites in Unity?

问题描述

我正在创建一个无限的地形生成器，我需要在玩家四处移动时不断更新地形.

I am creating an infinite terrain generator and I need to constantly update the terrain as the player moves around.

一切都很好，但是我很难找到有关快速创建和渲染Sprite的最快方法的信息.

Everything is fine, but I am having trouble with finding information about the fastest method of creating and rendering sprites on the fly.

有关精灵的信息:

我正在使用1张精灵表，其中包含我的地形所需的所有帧.草，沙，水等全部集中在一个单个的.png文件中.所有帧都存储在一个数组中，我可以从中轻松抓取它们.

I am using 1 sprite sheet which has all the frames I need for my terrain. Grass, sand, water etc. all in 1 single .png file. All frames are stored in an array from which I can easily grab them.

当前需要正确显示我的精灵对象的步骤:

1. 创建新对象.
2. 设置其在2d空间中的位置.
3. 添加组件.
4. 根据需要缩放它们.

生成的精灵存储在名为chunk的GameObject数组中.这是我目前生成子画面的方式.

Generated sprites get stored in a GameObject array called chunk. This is the way I am currently generating sprites.

        chunk[i] = new GameObject();
        chunk[i].gameObject.transform.position = new Vector2(spriteCoordX, spriteCoordY);
        chunk[i].AddComponent<SpriteRenderer>();
        SpriteRenderer renderer = chunk[i].GetComponent<SpriteRenderer>();
        renderer.sprite = tiles[calculatedFrameId]; //Set correct sprite frame.
        chunk[i].gameObject.transform.localScale = new Vector2(6.75f , 6.75f);

我不知道，每次我想在代码中创建一个新的精灵时，添加组件并进行缩放似乎是多余的和不必要的，而且我确信有更好的方法来做到这一点.

I don't know, adding component and scaling every single time I want to create a new sprite in code seems redundant and unnecessary and I am sure there is a better way to do that.

总结:

我需要最好的(最快的)方式来生成大量精灵，设置其帧，位置和适当的比例.

I need the best (fastest) possible way to generate large number of sprites, set their frame, position and proper scale.
