◆ ValidateNativeTexturePointers()

void TiltFive.SplitStereoTextures.ValidateNativeTexturePointers ( )

Determines whether the left/right texture handles are still valid, and resets them if needed

This should be executed in OnPreRender(), otherwise IsCreated() always returns true

Definition at line 104 of file SplitStereoTextures.cs.

         {
             /* Render textures have a state (created or not created), and that state can be invalidated.
             There are a few ways this can happen, including the game switching to/from fullscreen,
             or the system screensaver being displayed. When this happens, the native texture pointers we
             pass to the native plugin are also invalidated, and garbage data gets displayed by the glasses.
  
             To fix this, we can check whether the state has been invalidated and reacquire a valid native texture pointer.
             RenderTexture's IsCreated() function reports false if the render texture has been invalidated.
             We must detect this change in OnPreRender(), because IsCreated() reports true within Update().
             If we detect that the render textures have been invalidated, we null out the cached pointers and reacquire.
             */
  
             // Check whether the render textures' states have been invalidated,
             // and reset the cached texture handles if so.
             if (!LeftTexture_GLS.IsCreated() || !RightTexture_GLS.IsCreated())
             {
                 LeftTexHandle = System.IntPtr.Zero;
                 RightTexHandle = System.IntPtr.Zero;
             }
