i need help to make my own class (solved)

[noals]

hi,

first of all, for those who noticed, few times i posted and then deleted my post, its just that i found the answers to my questions so if there is no answer yet, i just delete, sorry if it annoyed some, dunno, just telling.

anyway, i try to make my own class and since im not familiar with the whole process, im kinda stuck already.
here is my code :

ImyRagdollSceneNode.h

and how i try to use it :

Code: Select all

 
    //ragdoll test
    scene::ImyRagdollSceneNode*myRagdoll = new scene::ImyRagdollSceneNode(
        core::vector3df (0.0f,0.0f,0.0f),       //ragdoll position
        core::vector3df (0.0f,0.0f,0.0f),       //ragdoll rotation
        0,                                      //ragdoll state, animation
        0,                                      //ragdoll ID
        smgr,               //pointer
        0,                  //parent node
        -1);                    //ID

but vc++ underlign the second "scene" and tell me:

object of abstract class type "irr::scene::ImyRagdollSceneNode" is not allowed

on an irc channel someone told me that it could be a missing virtual void stuff()=0; but i dont really understand.
did i forgot something before trying to make any calculs and stuff ?
can someone help me fixing it ?

The specific error you're getting is due to the fact that Irrlicht defines several member functions of the ISceneNode class that are "pure virtual" functions. This means that the compiler has been told to expect these functions to be defined in any sub class of ISceneNode, but they haven't actually been defined as of yet. That error is the compiler telling you "your class has functions that should be defined but aren't, so I can't instantiate it."

The functions I had to implement in my custom scene node were:

Code: Select all

 
void OnRegisterSceneNode(); //You have this already
void render(); //And this
u32 getMaterialCount();
SMaterial& getMaterial(u32 i);
aabbox3df& getBoundingBox();
 

I hope that helps!

i just needed to add the bounding box.
i have problems of redefinition now because of my .cpp but i know how to fix it.

thx for help.

[noals]

well i though i was able to solve it but the problem is a little different than what i had in mind.

        }

from .h

                ISceneNode* parent = 0,         //parent node
                s32 id = -1                     //ID
            );

i guess my smgr isnt initialized well or something, any idea ?

[noals]

well i will use another class from irrlicht 1.7.3 as exemple i think.
actualy i was able to make a class like that working years ago (my first class ever and im trying my second lol) but it was also with an old version of irrlich so i guess its maybe the source of my problem since i use my old class as exemple.

i will try again from the start.

1>ImyRagdollSceneNode.cpp(18): error C2572: 'irr::scene::ImyRagdollSceneNode::ImyRagdollSceneNode' : redefinition of default parameter : parameter 7

default parameter belong to the header file not to the source file

[noals]

default parameter belong to the header file not to the source file

thx a lot, it compiled.

i just had to change that :

Code: Select all

            ISceneNode* parent = 0,     //parent node
            s32 id = -1                         //ID

to that :

Code: Select all

            ISceneNode* parent,     //parent node
            s32 id                        //ID

im glad it was this simple, i dont have to do it all again and can continu my stuff, thx again.
