IDirect3DDevice7::BeginStateBlock

The IDirect3DDevice7::BeginStateBlock method signals Direct3D to begin recording a device state block.

HRESULT BeginStateBlock();

Parameters

None.

Return Values

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be one of the following values:

Remarks

This method was introduced with the IDirect3DDevice7 interface.

Applications can ensure that all recorded states are valid by calling the IDirect3DDevice7::ValidateDevice method prior to calling this method.

The following methods can be recorded in a state block (that is, after calling IDirect3DDevice7::BeginStateBlock and before IDirect3DDevice7::EndStateBlock):

• IDirect3DDevice7::LightEnable
• IDirect3DDevice7::SetClipPlane
• IDirect3DDevice7::SetLight
• IDirect3DDevice7::SetMaterial
• IDirect3DDevice7::SetRenderState
• IDirect3DDevice7::SetTexture
• IDirect3DDevice7::SetTextureStageState
• IDirect3DDevice7::SetTransform
• IDirect3DDevice7::SetViewport

The ordering of state changes in a state block is not guaranteed. If the same state is specified multiple times in a state block, only the last value is used.
