Diamond Duel

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a browser-based 3D baseball timing game titled “Diamond Duel: Nine Inning Showdown.” Use a dark navy/blue-green presentation with a fixed elevated perspective camera looking down the center of a stylized baseball diamond from behind home plate, showing a green circular outfield, brown four-sided dirt infield, white home plate and bases, chalk foul lines, a pitcher’s mound, distant dark outfield wall, and foul poles. Add soft shadows, fog, warm directional stadium-like lighting, cool rim lighting, and simple low-poly/mini-arena styling. Include a visible white baseball with a red seam, a wooden tan bat near home plate, and simple low-poly humanoid character models for the batter, pitcher, and runners. Decorative stadium banners and a small trophy may appear around the field, matching the understated low-poly 3D look.

The game is a nine-inning single-player batting showdown. The player bats during the top half of each inning and must time one swing per incoming pitch. Begin each pitch with the ball traveling from the pitcher toward home plate; the ball should be clearly visible moving toward the plate. The player can press the large on-screen “SPACE BAR” button or the keyboard Space key. Display a “NOW!” timing cue while the ball is in the plate window, but let the player swing at any time before the pitch finishes. The swing evaluates timing by how close the ball is to the plate and a smaller accuracy component based on horizontal alignment. Animate the bat through a full swing and animate the batter with a melee/attack motion on a hit or a kick/miss motion on a miss. Only allow one swing per pitch.

Use the following outcome rules: a well-timed swing produces a single, double, triple, or home run based on quality. A single puts the batter on first and advances existing runners one base; a double places the batter on second and advances runners; a triple places the batter on third and scores runners; a home run scores the batter plus all runners and clears the bases. Show the ball flying into the field after contact with different trajectories, including higher/farther flight for a home run, and finish the play before the next pitch. A poorly timed swing is a swing-and-miss strike. If the player does not swing before the ball crosses home plate, call it a strike. Track balls-strikes count as displayed, although this implementation awards strikes for misses and called pitches rather than walks. Three strikes create an out, reset the strike/ball count, and three outs end the half-inning. Show occupied bases visually by turning the relevant base warm yellow and placing simple runner models on first, second, or third.

After three outs in the top half, switch to the bottom half: reposition the batter and pitcher to swap sides and hide the bat/player swing button because the player is now pitching. The bottom half is an automatic transition phase; display “PITCHING” and a message such as “You are pitching — the batter will face the next pitch,” then proceed to the next half without adding a separate pitching control mechanic. After three outs in the bottom half, advance to the next inning, clear the bases and count, and continue. Play through nine innings, then stop and show GAME OVER with a final score message such as “Final score: X runs after 9 innings.” Provide a RESTART button and allow the R key to restart after game over.

Build a responsive HUD over the canvas. At the upper left, use a translucent dark rounded panel with a gold uppercase “DIAMOND DUEL” label, the title “Nine Inning Showdown,” and the subtitle “Time your swing. Own the moment.” At the upper right, use another translucent rounded stats panel showing large values for Runs, Count in balls-strikes format, Half (for example T1 for top of the first and B1 for bottom), and Outs. Center a translucent rounded message panel below the header for status text such as “Top of the inning — batting. Pitch incoming…,” “Swing and miss,” “SINGLE — batter on first,” or inning transitions. Near the bottom center show the instruction “Press the SPACE BAR when the ball reaches the plate,” and beneath it a large rounded yellow-to-orange gradient button labeled “SPACE BAR.” Hide or replace that button during the bottom half and after game over. Use polished dark glass-like panels, white text, gold accents, responsive sizing, and touch-friendly controls.
