Happiness/Friendship is an important feature you must understand in order to be able to evolve certain Pokémon in Vortex v3. Not all Pokémon need it to evolve. It is a measurement of how much a Pokémon is attached to its trainer and enjoys being in their care.
Here is a detailed breakdown of how Happiness works:
Happiness on Vortex, unlike the real games is not based on walking/giving your Pokémon a soothe bell or certain vitamins/herbs
Your Pokémon's Friendship will depend on the number of battles you fight, in other words your Pokémon's friendship goes up per battle, and more the friendship - The more happiness will raise. For ease of access, happiness in vortex has been customized and is based on the number of hearts a Pokémon has, which shows how happy it is. To know the number of hearts your Pokémon has, simply click on it.
FAQ
Q - How will I know how soon my Pokémon will get a heart/After How many battles will my Pokémon get a heart?
A - After each battle, your Pokémon randomly gets 1 or 2 happiness points which you cannot check. A Pokémon's maximum happiness points is 255, when it has 4 hearts.
Trivia
- Each heart needs 73 points.
- In other words, 1st heart will need 73 points, second will need 146 points, 3rd heart will need 220 points and 4th will need 255 points (max).
- All Pokémon which evolve by friendship except Sylveon need 220 points (3 hearts) for evolution.
- Eevee will need 255 Happiness points in order to evolve into Sylveon.
- Maximum number of battles which could be needed for a heart=73/1=73 battles.
- Mimimum number of battles which could be needed for a heart=73/2=36 battles.
- Since the happiness points per battle is randomized(1 or 2), you would need somewhere between 36 and 73 battles in order to gain 1 heart for your Pokémon.
