Reload/Reset Texture2D in XNA Windowsphone

I'm manipulating a Texture2D with Texture2D.Setdata and change its color.

But i want to reset the Texture2D after a Time again, currently im having the whole Texture Datas in Memory, but now i have OutOfMemoryExceptions in my App.

I Tried this:

Color[] bla = new Color[thetexture.Width * thetexture.Height];
this.Content.Load<Texture2D>(".\\textures\\mytexture").GetData(bla);
thetexture.SetData(bla);

But it doesn't change anything, the texture just stays colored.

How can I reset the texture, so that it looks like freshly loaded, but with a small Memoryuse?

Solution

  • ContentManager caches objects. Your call to Load is returning what is presumably the same object as your thetexture (the one you already modified).

    You need to load a separate instance of your texture with the original data. You need a separate ContentManager for that. Possibly one that has been customised to never cache objects.

    Alternately, create a new Texture2D object and copy the original data into that before modifying it, leaving the original untouched.
