Hi there.
I'm trying to speed up a Drawing routine in my GameEngine which traverses accross an std::vector of "Sprites"
The issue I have is that the Draw function that the Sprites can execute requires a parameter, a windows HDC in order to work properly, but I've not found a way of allowing that in without an error.
The final parameter in parallel_do is the problem:
"
error C2064: term does not evaluate to a function taking 0 arguments
[cpp]void GameEngine::DrawSprites(HDC hDC)
{
// Create a new instance of DrawList
DrawList m_DrawList;
m_DrawList.m_hDC = hDC; // me trying to plug the HDC in...
// Draw the sprites in the sprite vector
vector
::iterator siSprite;
tbb::parallel_do(m_vSprites.begin(), m_vSprites.end(), m_DrawList());
// for (siSprite = m_vSprites.begin(); siSprite != m_vSprites.end(); siSprite++)
// (*siSprite)->Draw(hDC);
}[/cpp][sectionbody]Here's my "Body" object. It's Error free currently, though I can't pass it a variable from outside[/sectionbody][cpp]class DrawList
{
public:
HDC m_hDC; // My attempt at storing the HDC, and passing it into
// the class seperately in GameEngine::DrawSprites
DrawList() {};
void operator() (Sprite* siSprite) const { //siSprite comes from vector container
(siSprite)->Draw(m_hDC); //need to pass the HDC in order to work
}
};[/cpp]
[sectionbody]Of course, I might be barking up the wrong tree trying to use parallel_do. Correct me if I'm wrong..[/sectionbody][sectionbody]
