Let's remove some items
We can now add items to the inventory, so let's see whether we can remove them
too. Add this bit of code under our previous test code:
if(Input.GetButtonUp("Fire2"))
{
GameObject test2 = new GameObject();
test2.name = "Sword";
RemoveFromInventory(2, test2);
}
When we click the right mouse button, we again create a new GameObject. We also
set its name to
"Sword" and
then call the
RemoveFromInventory
function. In
the function call, we pass the
2
and the
test2
GameObject. Now, when we run our
game and click the right mouse button, it will remove two of the sword objects from
our inventory. If
"Sword"
has a value of zero or less, the inventory slot will be set to
our
Empty
object.
To make sure this works, run the scene and left click your mouse a few times to
add a bunch of swords to the inventory. Now right-click a few times to remove some
swords. You can even remove them until you don't have any swords left and the slot
will be empty.
