Tilemap.SetTilesBlock

Parameters

Description

Fills bounds with array of tiles.

This is meant for a more performant way to set tiles as a batch, when compared to calling SetTile for every single tile. The bounds size must match the array size. For example bounds of 1x2x3 needs an array length of 6.

// Fill area on tilemap with checkerboard pattern of tileA and tileB
using UnityEngine;
using UnityEngine.Tilemaps;

public class ExampleClass : MonoBehaviour
{
    public TileBase tileA;
    public TileBase tileB;
    public BoundsInt area;

    void Start()
    {
        TileBase[] tileArray = new TileBase[area.size.x * area.size.y * area.size.z];
        for (int index = 0; index < tileArray.Length; index++)
        {
            tileArray[index] = index % 2 == 0 ? tileA : tileB;
        }
        Tilemap tilemap = GetComponent<Tilemap>();
        tilemap.SetTilesBlock(area, tileArray);
    }
}
