Halo syle health Shield regeneration?

I’m probably not the first one to ask for assistance on this but I would like to set up a health system similar to halo where shields recharge. Could I use the shooter game template as a basis modifying the existing health system? Or would you recommend starting from scratch? Any help is appreciated.

you can use whatever health system you like. After the shield has taken damage, set a timer to go off after a given time limit that will call an event to start increasing the health/shield. You can use the OnTick event to increase the health until you reach max health.
