As someone who used the ability to setup custom piece arrangements in Battlechess to see all the animations:
Place the enemy king in middle. Use four rooks at the edges of the board (two on the left, two on the top) to ensure the king can't move off his square. Give him a pawn to move to avoid a stalemate ending. Then place your desired checkmating piece where it can take one move and threaten the enemy king.
