Texture2D.Apply

パラメーター

説明

SetPixel 関数と SetPixels 関数による変更を適用します

If updateMipmaps is true, the mipmap levels are recalculated as well, using the base level as a source. Usually you want to use true in all cases except when you've modified the mip levels yourself using SetPixels. By default updateMipmaps is set to true.

If makeNoLongerReadable is true, Unity will free the memory used to store the CPU-addressable copy of the pixel data after uploading it to the GPU. isReadable becomes false. By default makeNoLongerReadable is set to false.

Apply is a potentially expensive operation, so you'll want to change as many pixels as possible between Apply calls.

Alternatively, if you don't need to access the pixels on the CPU, you could use Graphics.CopyTexture for fast GPU-side texture data copies. Note that calling Apply may undo the results of previous calls to Graphics.CopyTexture.

テクスチャはインポート設定で読み取り可能フラグが設定されている必要があります。

// Create a new texture and assign it to the renderer's material
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Start()
    {
        Texture2D texture = new Texture2D(128, 128);
        GetComponent<Renderer>().material.mainTexture = texture;

        for (int y = 0; y < texture.height; y++)
        {
            for (int x = 0; x < texture.width; x++)
            {
                Color color = ((x &amp; y) != 0 ? Color.white : Color.gray);
                texture.SetPixel(x, y, color);
            }
        }
        texture.Apply();
    }
}
