ID3DXEffectStateManager::SetTextureStageState

A callback function that must be implemented by a user to set the texture stage state.

HRESULT SetTextureStageState(
  DWORD Stage,
  D3DTEXTURESTAGESTATETYPE Type,
  DWORD Value
);

Parameters

Stage

[in] The stage that the texture is assigned to. This is the index value in IDirect3DDevice9::SetTexture or IDirect3DDevice9::SetTextureStageState.

Type

[in] Defines the type of operation that a texture stage will perform. See D3DTEXTURESTAGESTATETYPE.

Value

[in] Can be either an operation (D3DTEXTUREOP) or an argument value (D3DTA), depending on what is chosen for Type.

Return Values

The user-implemented method should return S_OK. If the callback fails when setting the device state, either of the following will occur:

• The effect will fail during ID3DXEffect::BeginPass.
• The dynamic effect state call (such as IDirect3DDevice9::SetTextureStageState) will fail.
