In this week we already completed our inventory script. The inventory bar will appear at the top of the screen. Player can click the item to add that item into the inventory. To use the item, player will only need to drag and drop the item from inventory to the targeted area. After the item collide with the targeted area, some effect will be applied. We also add the shooting mechanism that similiar to angry bird shooting mechanism (the shooting power will be determine by how long the player pressing the space bar). In next week we will balance the shooting power and the inventory system.
