Everything, himself asked himself replied, as usual:))
Here is a working script - "connector" with your script:
using UnityEngine;
using System.Collections;
using HutongGames.PlayMaker;
public class ShipSpeedToMotionBlur : MonoBehaviour
{
public PlayMakerFSM behavior;
public string fsmFloat;
public float MultSpeed;
void Update ()
{
MultSpeed = behavior.FsmVariables.GetFsmFloat(fsmFloat).Value; // Get float variable from FSM
GetComponent<MotionBlur>().blurAmount = MultSpeed; // Send float variable from FSM to my script
}
}
Thank you all, and all are free))
PS: Support - not bad to make a similar custom action!
