setScale and getScale crash my program (SOLVED: MY FAULT)

[FumarMata]

Hello everybody

It seems that a setScale is crashing my program. I want to change the scale.Y of an array of objects. Everything goes fine, but after a while, 10-15 seconds, the program crashes

If I comment the setScale command, the program doesn't crash

Code: Select all

core::vector3df scule;

...

while(device->run()) {
    for(int i=0;i<numamp; i++){
        for(int k=0;k<numalc; k++){
            scule.Y =hfinalarea[i][k];
            nodeW[i][k]->setScale(scule);
        }
    }
}

I'm stuck in this... could you help me? :?

Thanks!

I'd be willing to bet that the problem is not with setScale(). Are you absolutely sure that the scene node pointer stored at nodeW[k] is not an invalid pointer?

Hello Vitek

Yes, I'm completely sure, because the movie works during a few seconds, changing the scale of the nodes till it crashes

I have also changed numalc and numamp for absolute values to be sure that nodeW[k] is a valid pointer, but it made it crash too

Now I think that the problem is related to the mysql library / queries that I'm using...

Do you know a way to debug this (software, technique,...)? I'm using dev-c++

(still stuck )

Thanks

I forgot to say: also, if I try to getscale, instead of set the scale, it crashes too...

Which makes it pretty sure that you're invalidating your pointers somehow. Maybe some other code is overwriting the array? Or you drop() some elements?

Hello Hybrid

Which ways could I be invalidating my pointers? (I’m not dropping any element)
-overwritting the array
-some others?

This way I'll check this later. Could a pointer to a variable length string (the mysql query) be interfering with that?

Sorry for my imprecision... I'm really newbie on all this

Thanks!

Buf!

Finally I found the problem... I was not checking correctly the data that I was getting from the database, so at a certain point I was referencing to a node that didn't exist => CRASH!

Sorry for annoying you with this stuff :s

Thanks
