Hello, how are you? I'm a huge fan of your game here in Brazil, and I'd like to offer some suggestions and report a few bugs.
🐞 Bugs
Block Collision Issue: The physics, when you go to use the opposing team's block (I'm not sure what the English term is, LOL), is acting strangely. When the block is being set up and you spike the ball, if it goes out, the ball often collides with an invisible wall. This seems to be a problem with the hitbox interacting with the rigid body.
💡 Suggestions
Implement More National Teams/Selections.
Implement International Team Tournaments (like the Olympics, etc.).
Implement Two More Player Positions: The Libero and the Opposite Hitter (or 'Saída de Rede').
Implement Non-Local Multiplayer (Online Multiplayer).
I want to make it clear that I understand how difficult it is to implement these features. I am a graduated game programmer here in Brazil, and if you would like some external suggestions, I can send you some code I implemented in a test mini-game similar to yours (but not for sale, just for fun).
🕹️ Proposed Controls for Opposite Hitter / Parallel Attack & Block
I would now like to add a new Opposite Hitter attack option.
Opposite Hitter Attack: You would move the analog stick down (or the down arrow on the keyboard, or the S key) to select it, and then use a separate button for the parallel attack, such as Y (Xbox), Triangle (PlayStation), or Q (Keyboard).
Counterpart Block Control: In contrast, the block would be: Y (Xbox Block), Triangle (PlayStation Block), or Q (Keyboard) for the parallel block.
Defense Mechanic: Regarding defense, the defense would only be triggered on the attacker's side, allowing for double blocks on broken plays.
