Re: [PD-dev] help-array crashing outlet_anything - Pd-dev

      SOLVED.(somewhat)
Instead of using the addToArray function I just used something like this:
Intstore *storepointer;
In my function I used this:
storepointer = new Intstore[anumber];
for (i=0; i<anumber; i++) {
storepointer[i].m_xmax = (whatever int);
storepointer[i].m_ymax = (whatever int);
}
So to send it out an outlet I do this:
t_atom*ap = new t_atom[2+anumber*2];
for(bn=0; bn<anumber; bn++){
    	SETFLOAT(ap+bn*2, x->storepointer[bn].xmax());
    	SETFLOAT(ap+bn*2+1, x->storepointer[bn].ymax());
}
outlet_anything(x->outlet1, 2+anumber*2, ap);
...and it works now. Simple and without too much hassle.
I still dont understand why it worked before but only with quicktime movies!  Makes no cense at all?

Ok I tried with a static array like "Class array[amount] " and it did not crash, it worked perfect. Now I 
have to figure out what I am doing to cause a crash (with heavy cpu load I persume, still a bit 
confused?) using a dynamic array? It would be nice to have a dynamic array so as not to eat up so 
much ram.

It doesn't thats whats confusing me.  Pixel data is the same on both exept it takes more cpu to 
process. I think it has to do with cpu load but I am not sure.  I think I am going to just try a simple 
"Class array[amount] " intead of "Class *pointer = new Class[amount]" see if that would be easier

the cpu or the coding gods.

BTW its a blobtracking external.  It is working perfect tracking quicktime
movies but the camera
tracking only works if I exclude the addToArray function. This really has
me scratching my head!
Why would your processing code know or even care if the input is from a
camera or a file?  Both should be pixel arrays with no differences in their
format.
