Inheritance problem
Author
Hello, I have a base structure and two sub structures that inherit from it. Then I have a function that takes a BASEVERTEX parameter. When I pass in DIFFUSEVERTEX it converts just fine to a BASEVERTEX, but when I pass in UVVERTEX I get weird number that werent in the original UVVERTEX.
You get a wierd number for the u and v coordinates or a wierd number for the positioN?
The inheritance structure looks OK. At least, you're not doing anything obviously wrong. Post the function that takes BASEVERTEX and I'll see what I can do.

Here is the function
And this is where I call it
void CalculateBoundingBox(BASEVERTEX *vertices, long numOfVerts){ for(int i = 0; i < numOfVerts; i++) { //Calculate the X min and max if (vertices.Position.x < boundingBox.min.x) { boundingBox.min.x = vertices.Position.x; } if (vertices.Position.x > boundingBox.max.x) { boundingBox.max.x = vertices.Position.x; } //Calculate the Y min and max if (vertices.Position.y < boundingBox.min.y) { boundingBox.min.y = vertices.Position.y; } if (vertices.Position.y > boundingBox.max.y) { boundingBox.max.y= vertices.Position.y; } //Calculate the Z min and max if (vertices.Position.z < boundingBox.min.z) { boundingBox.min.z = vertices.Position.z; } if (vertices.Position.z > boundingBox.max.z) { boundingBox.max.z = vertices.Position.z; } }}And this is where I call it
//This constructor worksQuadrilateral(D3DDevice *pD3DDevice, DIFFUSEVERTEX vertex1 = DIFFUSEVERTEX( 0.0f, 0.0f, 0.0f, BLACK), DIFFUSEVERTEX vertex2 = DIFFUSEVERTEX(50.0f, 0.0f, 0.0f, BLACK), DIFFUSEVERTEX vertex3 = DIFFUSEVERTEX( 0.0f, 50.0f, 0.0f, BLACK), DIFFUSEVERTEX vertex4 = DIFFUSEVERTEX(50.0f, 50.0f, 0.0f, BLACK) ){ texture = NULL; diffuseVerts[0] = vertex1; diffuseVerts[1] = vertex2; diffuseVerts[2] = vertex3; diffuseVerts[3] = vertex4; CalculateBoundingBox(diffuseVerts, 4);}//This constructor get incorrect resultsQuadrilateral(D3DDevice *pD3DDevice, Texture *pTexture, UVVERTEX vertex1 = UVVERTEX( 0.0f, 0.0f, 0.0f, 0.0f, 0.0f), UVVERTEX vertex2 = UVVERTEX(50.0f, 0.0f, 0.0f, 1.0f, 0.0f), UVVERTEX vertex3 = UVVERTEX( 0.0f, 50.0f, 0.0f, 0.0f, 1.0f), UVVERTEX vertex4 = UVVERTEX(50.0f, 50.0f, 0.0f, 1.0f, 1.0f) ){ texture = pTexture; uvVerts[0] = vertex1; uvVerts[1] = vertex2; uvVerts[2] = vertex3; uvVerts[3] = vertex4; CalculateBoundingBox(uvVerts, 4); }
I can't see anything directly wrong with it.....what piece of UVVERTS is wrong after those constructor calls?

The numbers are screwed up such as Z for the second vert is 50, and X and Y for the 3rd and 4th vert are -1.58795 or something. I put a break point on the function call, and its fine before, but then when it gets to the function the data is a screwed up.

I can put the UVVERTEX for the function parameter and it works fine. I just dont want a function for every type of vertex.
