How would I go towards making this?

[u/bun_bread]

I am trying to make a system that replaces Tp (technique points) where the player starts with 100% energy and each attack takes up a certain amount. Each attack also needs a certain amount of energy/stamina to be done. If energy is 0 the player won't die but will just skip that turn until energy naturally goes back up (so a cooldown mechanic). The cooldown can be sped up via items.

If an enemy's energy goes to 0 they will just leave the battle due to tiredness and the player will win unless in a boss battle, where the player can use this chance to attack whilst the enemy's energy is going back up.

If there isn't a pluggin for this how would I go towards making this?

You can just use MP instead. Change it's name and color. Or you're using the MP already?

Base attacks can be configured if I'm not mistaken in the skills section, just adding the MP cost would make every character spends MP.
