  Understanding plug-ins writing

  Posted by Jagi88 on July 26, 2006 at 12:07 pm

  Hi,
  I started studying AE SDK, and I have problem with understanding it. It goes about Skeleton template plug-in. There is the Render function. Here is the code:

  static PF_Err
  Render (
  PF_InData *in_data,
  PF_OutData *out_data,
  PF_ParamDef *params[],
  PF_LayerDef *output )
  {
  PF_Err err = PF_Err_NONE;
  AEGP_SuiteHandler suites(in_data->pica_basicP);

  /* Put interesting code here. */

  ERR(suites.WorldTransformSuite1()->copy(in_data->effect_ref,
  &params[SKELETON_INPUT]->u.ld,
  output,
  NULL,
  NULL));

  return err;
  }

  First: What is the ERR mackro doing? There is no description in SDK.
  Second: What is WorldTransformSuite1() and what is it doing? I’v never see write : function->member_function, so it’s looks like WorldTransformSuite1() is stucture initialization, however, in the class of object suites isn’t any declaration of this structure/function.
  Could someone explain it to me?

  PS. Sorry for my english, I hope that i didn’t do too many mistakes.
