I meen before wining the game how can I make unit stand What Ever Way I wan't ? do I need trigger or what?Well upon winning the game you can use a Unit Group to select all units in map and play there Stand Victory animation
what Trigger Will MAKE THGE UNIT HAVING STAND what EVER position DO IT?You can only make a unit do animations that it already has. You can "play" these using the animation triggers.
The only possible exceptions I can think of are the Lock Body Part Facing triggers.
