1 TileMap概念

Tilemapis used to create2Dgame world map,Common side view、俯视、斜45angle of view2DIt can be used to draw game maps.

主要思想

Draw each type of terrain in the game world as a separate block,例如RubyAdventureThe project resources provide different terrains that can be used to generateTile的精灵：

用正方形、菱形或者六边形One of the three as the shape of each piece separates the whole piece,Again like tiles/Assembled like tiles.on how to divide,后续会进行介绍.

优点

Improve the reusability of art resources,And using such a tool can greatly simplify the workload of mapping.

created hierarchy

一般在一个2D游戏项目中,TilemapCreation will be divided into three levels

• background——地图背景
• bound——边界
• foreground——前景,Mainly terrain

2 Unity中的TileMap

Unity中TileMapis used as a game object,for storage and handlingTile Assets,It's more like a system,将Tilestransfer to other related components.

Unity中的TileMap由五个部分组成：

2.1 auto parentGrid 网格

创建一个Tilemap：

GameObject -> 2D Object ->Tilemap选择类型

When we follow this path to create one瓦片地图时,UnityA parent object of the current tilemap object is automatically created（默认名称叫Grid）,这个GridIt is equivalent to a collection of connected grids,Each grid will store oneTile,Grid的Cell Sizeand other properties can change the size of the grid.

2.2 Sprite精灵

在【Unity入门计划】基本概念(6)-精灵渲染器 Sprite RendererIntroduce what a sprite is,它其实就是一个2D的Texture容器.

2.3 Tile 瓦片

A tile contains a sprite and two components.创建方法：

Project窗口 -> Create -> 2D -> Tiles选择类型

新建的TileNeed to give it a sprite,That is to give it a texture.SelectYou can select the sprite.You can also change its collider type,默认是Sprite精灵.

2.4 Tile Palette 调色板

The tile map can be drawn quickly,There are two ways to create it：

第一,从Project面板创建

Project窗口 -> Create -> 2D -> Tile Palette选择类型

第二,创建了Tilemap后,从Scene打开PaletteWindow panel creation

Both require selection of the file path for storage.

2.5 Brush 笔刷

Tools in the palette for drawing tile maps.

3 Tilemap Renderer Tile map renderer

它是Tile MapA part of a GameObject,What the sprite renderer is for sprites,It is also used to control the currentTile在Tilemap上的渲染,有以下属性.

3.1 Sort Order The tile arrangement order

这个很简单,is to prescribe eachTile在整个Tilemapthe order of the above.The contextual relationship is reflected through the layer order.

3.2 Mode 渲染模式

渲染模式有两种

 Chunk 分块渲染

Use tiled mode for batch rendering,This is also the default rendering method,选择ChunkThe post renderer groups tiles by location,Batch render the sprites on the tile together,The best rendering performance can be obtained in tilemaps.

 Individual Render separately 

Render each tile individually and take into account position and sort order.

3.3 Detect Chunk Culling Bounds How to detect boundaries

有两个值,Auto和Manual,自动和手动.The default is automatic monitoring.At this point the renderer will automatically check the sprite used.当选择ManualWhen you need to enter a value for the proposed boundary extension.

3.4 Mask Interaction 遮罩

This is similar to the sprite renderer,就不赘述,Once you use it, you will know what it does.

3.5 Material 材质

Defines the material used to render sprite textures.

The rest is the layer relationship,不赘述.

4 The creation process of the tile map

4.1 创建Sprite&Tile

First you need a tile that you want to be a tile map elementTile,Also need sprites as textures,So usually one is passed in2DPictures as sprites.

例如RubyAdventureOne is given in the official tutorialPNG纹理素材,Import and willType改为Sprite 

下面是创建Tile,按照2.3The creation ideas in Create oneRule Tilebase tile,命名为BrickTile,And assign the sprite you just created to him.

4.2 创建Tilemap&Tile Palette

GameObject -> 2D Object ->Tilemap创建RectangularType of tilemap,Also the parent is created automaticallyGrid.

点开Palette Window,新建一个Palette命名为GamePalette,并将之前创建的Tile拖进去.

4.3 The tile map can be started

4.4 问题处理：Grid有缝隙

如下,The tile does not fill the entiretyGrid

更改TilemapThe pixel size of the sprite,更改成64即可.

修改后的结果：

This is how the tilemap is initially created,But for general projects,Provided will be a collection of multiple tiles,02section will introduce aboutTile的其他方面的内容.
