[Help] Bounding boxes

[Nitr0]

Is it possible to create bounding boxes using a model rect of strides, numvertices and so forth?

In the games that use SetTransform, sure.

Getting an objects matrix from within DIP

Even if they don't, in a lot of games you can call "GetVertexShaderConstantF" and grab some values you might need, case and point, BFBC2:

PHP Code:

BOOL CBFBC2Engine::GetProjectionMatrix( D3DXMATRIX* Projection )
{
    if( Projection == NULL )
        return FALSE;

    if( CRender::Get() == NULL )
        return FALSE;

    if( CRender::Get()->DirectXDevice == NULL )
        return FALSE;

    if( FAILED( CRender::Get()->DirectXDevice->GetVertexShaderConstantF( 2, *Projection, 4 ) ) )
        return FALSE;

    return TRUE;
}

BOOL CBFBC2Engine::GetWorldMatrix( D3DXMATRIX* World )
{
    if( World == NULL )
        return FALSE;

    if( CRender::Get() == NULL )
        return FALSE;

    if( CRender::Get()->DirectXDevice == NULL )
        return FALSE;

    if( FAILED( CRender::Get()->DirectXDevice->GetVertexShaderConstantF( 1, *World, 4 ) ) )
        return FALSE;

    return TRUE;
}

Might be quite a noob mis-understanding but i have never worked with GetVertexShaderConstantF but how exactly do you go about getting the "Start Register", and "Register Count".

You can look up "ntKid" posts on here, WorldToScreen example, he wrote a function to dump the assembly of a shader and also another function to dump the constants.

Thanks, so it is possible.
