HandView: Preview cards on hover

[StefanoFiumara]

Create an animation to preview a card when the player hovers over the card in their hand.

Implementation

• Divide lower section of screen into x sections, where x is the number of cards in the player's hand
• When the player hovers over each section, animate the corresponding card to a preview position such that the card text is visible and above others in the hand.
• When the player hovers to another section, animate the card back to it's original spot in the hand
