There is animtree
http://www.q3.cz/images/40AnimTree.jpg

I have been trying to Referenced animation nodes within Unrealscript by this UDN tutorial

http://udn.epicgames.com/Three/AnimationNodes.html#Referencing%20animation%20nodes%20within%20Unrealscript

head (Referencing animation nodes within Unrealscript)

There is my out of action script :

/**
 * A custom blend list node that saves the index of the last active child before setting it.
 * This allows us to easily blend back to the last index when changing actions.
 *
 * @author Matt Stafford
 */

class ATAnimNodeBlendList extends AnimNodeBlendList;

var Name ATAnimNodeBlendList;
var AnimNodeBlendList f;
var array<AnimNodeBlendList> AllAnimNodeBlendLists;

/* 
 * Called after initializing the AnimTree for the given SkeletalMeshComponent that has this Actor as its Owner
 * this is a good place to cache references to skeletal controllers, etc that the Actor modifies
 */
event PostInitAnimTree(SkeletalMeshComponent SkelComp)
{
  local AnimNodeBlendList IdleNode01, DirectionalNode02;

  if (SkelComp == None)
  {
    return;
  }

  if (ATAnimNodeBlendList != '' && ATAnimNodeBlendList != 'None')
  {
    // Search for the animation node blend list by name.
    f = AnimNodeBlendList(SkelComp.FindAnimNode(ATAnimNodeBlendList));
    if (f == None)
    {
      `Warn("AnimNodeBlendList is none.");
    }
  }
  else
  {
    // Search for all animation node blend lists by class.
    ForEach SkelComp.AllAnimNodes(class'f', IdleNode01, DirectionalNode02)
    {
      AllAnimNodeBlendLists.AddItem(IdleNode01, DirectionalNode02);
    }
  }
}

Warning - ~\UDK-2011-09\Development\Src\EternalCrisis\Classes\ATAnimNodeBlendList.uc<39> : Warning, Unresolved reference to Class `f`

Failure - ~\UDK-2011-09\Development\Src\EternalCrisis\Classes\ATAnimNodeBlendList.uc<39> : Error, Call to `AllAnimNodes`, parameter 2: Type mismatch in Out variable

I just only copied script from UDN tutorial and tryed to fill.
I am a begginer, so its my first attempt and I have used Wraith´s tutorial assets.

I would like to ask what is wrong, maybe I figure out......
