Sequential file loading
Apr 24th, 2008, 12:08am  
i've got a sequence of .obj files, each one is a different key frame of animation for the same model that i created in Maya. I've made a script in maya that automates this process. I'm loading these into processing using my custom loader and interpolating the vertex values to create a rudimentary animation system.  Everything works fine but currently i'm loading it one by one.  It would be a hell of alot easier if i could load them sequentially. Also currently i'm loading my object using:

String frog1obj[];
importobj frog1;

void setup(){
 frog1obj =  loadStrings("frog1.obj");
 frog1 = new importobj(frog1obj);
}

then frog2 frog3 et cetera

what id'e like to do is:

importobj frog;

void setup(){
 frog = new importobj("frog*.obj")
}

So my 2 questions are:

a) how can i pass "frog.obj" as an argument to my class so that i can read it internally in my constructor using

frogobj = loadStrings("frog.obj");

b) if possible how do i load a bunch of files sequentially using wild cards.

There are no wildcards, but you can do

Code:

importobj[] frogs;

void setup()
{
  //...
  frogs=new importobj[numObjs];
  for(int i=0;i<numObjs;i++)
  {
    String[] tmp=loadStrings("frog"+i+".obj");
    frogs[i]=importobj(tmp);
  }
}


and as for doing it in a single step:
Code:
class importobj
{
  importobj(String filename)
  {
    String[] tmp=loadStrings(filename);
    //what is already in your current constructor
  }
}

And of course this removes the loadStrings thing from the setup() function above, and you pass "frog"+i+".obj" to your importobj constructor.
