Render to Texture again.

[Thareh]

Hi!

Seems like 'GetColorBuffer' isn't very good to use when rendering to a texture since it changes with the buffer even after you've used 'GetColorBuffer'. (Which also means that all the buffers I've used to render to texture probably doesn't get freed aswell)

I want a static function that saves the current state of the buffer, and doesn't change even if the buffer changes after the command.

Is there anything like this in LE?

I've tried all logical ways of doing this, such as:

LoadTexture( GetColorBuffer( Buffer ) )

LoadTexture( Buffer )

LoadTexture( SaveBuffer( Buffer ) )

etc.

 

Still can't get the TTexture to "unlink" from the buffer.

Dunno if i understood you correctly, but that is how i save the current backbuffer, when switching in pause mode:

TTexture TeLastRenderBeforePause = NULL;
TBuffer TempBuffer = CreateBuffer (GraphicsWidth (), GraphicsHeight (), BUFFER_COLOR0);
CopyBuffer (BackBuffer (), TempBuffer, BUFFER_COLOR0);
TexLastRenderBeforePause = GetColorBuffer (TempBuffer, 0);
FreeBuffer (TempBuffer);

The problem might be that I can't free a buffer since I'm using BlitzMax.

There's no FreeBuffer command, so I just nullify it and hope for the best.

But still, I want to be able to get a TTexture from a buffer, and then re-use the buffer without the TTexture changing.
