CheckCanDoThis

This C++ Function is found inside of CAdditionalVertexStreamManager.

It checks if --.

It can be found in Client/Client Core/Sources/CAdditionalVertexStreamManager.cpp in Visual Studio.

Required Arguments

• state: To be defined.

Returns

Returns a boolean value representing whether this can be done or not.

Code

bool CAdditionalVertexStreamManager::CheckCanDoThis ( const SCurrentStateInfo& state )
{
    if ( state.decl.numElements != 4 )
        return false;

    // Check vertex declaration requirements
    const D3DVERTEXELEMENT9* elements = state.decl.elements;
    if ( elements[0].Stream != 0 || elements[0].Type != D3DDECLTYPE_D3DCOLOR || elements[0].Usage != D3DDECLUSAGE_COLOR )
        return false;

    if ( elements[1].Stream != 1 || elements[1].Type != D3DDECLTYPE_FLOAT3 || elements[1].Usage != D3DDECLUSAGE_POSITION )
        return false;

    if ( elements[2].Stream != 1 || elements[2].Type != D3DDECLTYPE_FLOAT2 || elements[2].Usage != D3DDECLUSAGE_TEXCOORD )
        return false;

    if ( elements[3].Stream != 255 )
        return false;


    // Check vertex stream
    if ( !state.stream1.pStreamData )
        return false;

    if ( state.stream1.Stride != 20 )
        return false;

    if ( state.args.PrimitiveType != D3DPT_TRIANGLESTRIP && state.args.PrimitiveType != D3DPT_TRIANGLELIST )
        return false;

    return true;
