button sequence command, how to??

You could use a string as an input buffer with each input adding a command to the end and removing one from the beginning then you only have to do checks based on the last command in the sequence. So if it's checking "fire" it can parse the string at the beginning of the "fire" function and see if the previous inputs were "left-left-down-up-fire", if so branch off to the alternate function for the fatality.

Use the following class:

public class KeySequence { public delegate void HandleCallback(KeySequence pSequence); List<string> mKeyList = new List<string>(); int mProgressIndex = 0 ; HandleCallback mHCB = null;

 public KeySequence(HandleCallback pCallbackFunction)
 {
     mHCB = pCallbackFunction;
 }
 public void AddKey2Sequence(string pKeyStr)
 {
     mKeyList.Add(pKeyStr);
 }
 public void  Update()
 {
     if(mKeyList.Count==0)
     {
         return ;
     }
     if(Input.GetKey(mKeyList[mProgressIndex]))
     {
         mProgressIndex++;
         if(mProgressIndex>=mKeyList.Count)
         {
             if(mHCB!=null)
             {
                 mProgressIndex=0;
                 mHCB(this);
             }
         }
     }
     else
     {
         mProgressIndex=0;
     }
 }

}

Now you can make a keysequence like this:

KeySequence lTestSequence = new KeySequence(new KeySequence.HandleCallback(TestSequencePressed));
lTestSequence.AddKey2Sequence("left");
lTestSequence.AddKey2Sequence("right");
lTestSequence.AddKey2Sequence("left");

Then you put lTestSequence.Update() in your update routine.

Now when the sequence is correctly entere the function TestSequencePressed will be called with the sequence object that fired. You will have to declare this function somewhere of course :)
