I am relatively new to Processing but have been working in Java for about 2 years now. I am facing difficulty though with the translate() function for objects as well as objects in general in processing. I went through the examples and tried to replicate the manners by which they instantiated the objects but cannot seem to even get the shapes to appear on the screen no less move them. I instantiate the objects into an array using a nested for loop and expect a grid of the objects to be rendered. However, nothing at all is rendered. My nested for loop structure to instantiate the tiles:

for(int i=0; i<102; i++){
   for(int j=0; j<102; j++){
      tiles[i][j]=new tile(i,0,j);
      tiles[i][j].display();
   }
}

And the constructors for the tile class:

tile(int x, int y, int z){
this.x=x;
this.y=y;
this.z=z;
beginShape();
 vertex(x,y,z);
 vertex(x+1,y,z);
 vertex(x+1,y,z-1);
 vertex(x,y,z-1);
endShape();
}

Nothing is rendered at all when this runs. Furthermore, if this is of any concern, my translations(movements) are done in a method I wrote for the tile class called move which simply calls translate. Is this the correct way? How should one approach this? I can't seem to understand at all how to render/create/translate individual objects/shapes. Thanks for any help any of you are able to provide!
