Graphics / Attaching image to a sprite

« on: February 06, 2011, 03:04:34 pm »

hmm, that were my solutions, too. but when executing the code line-by-line in visual studio, the GetImage-function is called properly and the right image is returned. but after calling the SetImage-method and befor the tempRes is deleted, the sprite contains no image. so as i concluded, the deleting of the tempRes can't cause this problem. or am i wrong?

@ nexus
yes your right, there is a lot of redundance in my code, i just have to simplify it... :roll:
the manager returns the base class, but it would be better to overload the GetRes-function

Graphics / Attaching image to a sprite

i'm sure that i just mad a very stupid mistake but i can't help myself
here's my code

Code: [Select]


void CDrawable::SetResource(std::string strID)
{
m_strResourceID = strID;

CResourceBMP* tempRes;
tempRes = static_cast<CResourceBMP* > (RESOURCEMANAGER->GetResource(m_strResourceID));
m_pSprite.SetImage(tempRes->GetImage());
delete tempRes;
tempRes = NULL;
}
//------------------------------------------------------
sf::Image CResourceBMP::GetImage()
{
return m_pImage;
}


The GetImage() method hands over a reference to its image, but m_pSprite just contains a NULL-pointer as image after calling SetImage() so that the programm just draws white rectangles or i get an acces violating.
the RESOURCEMANAGER stores the resources in a map, but its already completed when setting the resources to the objects. so it can't be an error cause of moving the image in memory because the vector/map expands.

i don't see the forrest because of all the trees, as you say here in Germany;)
