A callback function that must be implemented by a user to enable/disable a light.
HRESULT LightEnable(
[in] DWORD Index,
[in] BOOL Enable
);
-
Index [in]
-
Type: DWORD
The zero-based index of the light. This is the same index in IDirect3DDevice9::SetLight.
-
Enable [in]
-
Type: BOOL
True to enable the light, false otherwise.
Type: HRESULT
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::LightEnable) will fail.
