Defining and using state objects
State objects are declared in FX files in the following format. StateObjectType is one of the states listed above and MemberName is the name of any member that will have a non-default value.
StateObjectType ObjectName {
MemberName = value;
...
MemberName = value;
};
For example, to set up a blend state object with AlphaToCoverageEnable and BlendEnable[0] set to FALSE the following code would be used.
BlendState NoBlend {
AlphaToCoverageEnable = FALSE;
BlendEnable[0] = FALSE;
};
The state object is applied to a technique pass using one of the SetStateGroup functions described in Effect Technique Syntax (Direct3D 11). For example, to apply the BlendState object described above the following code would be used.
SetBlendState( NoBlend, float4( 0.0f, 0.0f, 0.0f, 0.0f ), 0xFFFFFFFF );
