void Activate()
{
switch(selfAction)
{
case SelfAction.BuffDebuff:
BuffDebuffStat();
break;
case SelfAction.ChangeHP:
ChangeHealth();
break;
case SelfAction.ChangeArmor:
ChangeArmorAmount();
break;
}
if(selfType == SelfType.Potion)
Destroy(gameObject);
}
When this function is called, we use a switch statement to check the selfAction
variable. This is an easy way to see what the item should do when the player uses
it. At the end of the Activate function, we check to see what type of item it is. If it
is a potion, we destroy the GameObject. Not all items get destroyed upon use, such
as armor, so we use the selfType variable to determine what type of item it is.
