custom_mana_system.md

My Custom Mana System, currently in progress.

• UI in general could be improved and all feedback is appreciated;
• CardUI do not show correct costs yet;
• Not all features were fully tested.

Copy/Adapt all following scripts below.

On UI/Prefabs the changes were:

• Create your Manas
• Create an UI for each cost, like:
• In PlayerUI (both) setup the mana UI
• Create Mana Buttons (attach the ManaButton Script)
• Add Mana Buttons to CollectionPanel
• Update CardUI and HandCard (In my case a card will have up to 2 different mana costs)

Results:

• Setup mana in deck
• Receive more mana based on your deck
• Card Preview
• Generic Mana (will consume from 1st to last mana setup in deck)
