Mana and Spells System

A simple pattern showing the relation between spell usage and mana consumption.

How it works:

1. The “Mana Pool” Node has a limit of 100. If a spell is used, the mana is replenished at a rate of 1 per second by the “Generator” Node.
2. Each spell has a different mana cost and a different cooldown (except Spell 1, which can be cast continuously, as long as there’s enough mana).
3. The spells pull mana from the “Mana Pool” and either drain the Resources (Spell 1) or convert them in the cooldown amount designed for each spell.
4. While the amount in the cooldown Pool assigned to each spell is higher than 0, the spell can’t be used.
5. The cooldown Pools are drained constantly at a rate of 1 per second.
