This time there can be only one combo style.Or random combos can show up.
i.e.
*On any touch start / On key pressed*
If "Right Punch" is playing -> Set animation to [ Choose("Left Punch","Knee","Right Punch", "Shoulder hit", "Double Punch")]
If "Left Punch" is playing -> Set animation to [ Choose("Left Punch","Knee","Right Punch", "Shoulder hit", "Double Punch")]
something like that.
In this case the characters will make random combos.
