Basic combat

Make it so when you come within range of an enemy, it triggers a combat mode. In this mode your player cannot move. There should be an attack and a defend button. Attack button should use some stamina and do damage to the enemy health. Defend button should regenerate some stamina and make you take less damage than normal. If the enemy dies, end combat and give the player money. If the player dies, end combat and take away money, while leaving the player at one health. Make the enemy do a random amount of damage between 5 and 20 damage each round.
