Hey,
I am using TUniquePtr<uint8[]> PixelBuffer; to store pixel data of a texture as an array. Like iUltimateLP does it in his code.
The creation and drawing of the texture is working so far. (as shown in the picture below)
Now I am trying to create a copy of that array using a for loop. (I am using a for loop because I want to extract just parts of the texture later on. But just for demonstration I copy the array completly in this example.)
SIZE_T PartBufferSize = WorldTextureWidth * WorldTextureHeight * DYNAMIC_TEXTURE_BYTES_PER_PIXEL;
TUniquePtr<uint8[]> PartPixelBuffer = MakeUnique<uint8[]>(PartBufferSize);
for (int i = 0; i < WorldTextureHeight *WorldTextureWidth * DYNAMIC_TEXTURE_BYTES_PER_PIXEL; i++) {
PartPixelBuffer[i] = PixelBuffer[i];
}
The pixels after copying are mixed up and the picture is different every time I execute this code. (as shown on the picture below)
What am I doing wrong?
