Unity 3D Basic Game Platform

The game needs to be 3D. Login page: Username and Password (connected through mysqli to hostgator) Register page: First name, Last name, Username, Password, Confirm Password. (connected through mysqli to hostgator) If arrow keys pressed it changes the camera direction (camera rotation around the player) scroll to zoom in and out. Clicking: If the player clicks the map the players walks to the location (x,y,z) if the player clicks a monster the player walks over to the monster and attacks it unless the player has a Staff in hand (for magic) then the player stays at the (x,y,z) location and shoots magic ball or fire ball depending on which skill is selected in the skill tab. if the player clicks a tree and has a axe in the inventory tab then the player walks over to the tree and starts cutting it down. Once the tree is cut down the tree disappears leaving a stump and logs are inserted into the players inventory. If player clicks items are on the ground (weapon, coins, logs) the player walks over to the item and picks it up and it is inserted into the inventory. Inventory: The only item that is stackable (contains multiple in one inventory location) is coins . Need 28 inventory slots can be more. When a user right clicks on an item it gives them an option. If it is a weapon it gives them a option to wield it or drop it (left click automatically wields the weapon) If it is an item such as logs or coins it gives them an option to examine it which displays a brief description of the item or drop it. (two options drop item / examine) After the player kills a monster the monster drops coins at his (x,y,z) location. In a Stats tab the only stats I need in there are Hit Points, Attack, and Magic.
