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