# Piece Spawning and Font Enhancement - Implementation Report
|
|
|
|
## Overview
|
|
Fixed piece spawning position to appear within the grid boundaries and updated the gameplay UI to consistently use the PressStart2P retro pixel font for authentic Tetris aesthetics.
|
|
|
|
## Changes Made
|
|
|
|
### 1. Piece Spawning Position Fix
|
|
|
|
**Problem**: New pieces were spawning at `y = -2`, causing them to appear above the visible grid area, which is non-standard for Tetris gameplay.
|
|
|
|
**Solution**: Updated spawn position to `y = 0` (top of the grid)
|
|
|
|
#### Files Modified:
|
|
- **`src/Game.cpp`** - `spawn()` function
|
|
- **`src/Game.cpp`** - `holdCurrent()` function
|
|
|
|
#### Code Changes:
|
|
```cpp
|
|
// BEFORE: Pieces spawn above grid
|
|
cur = Piece{ bag.back(), 0, 3, -2 };
|
|
nextPiece = Piece{ bag.back(), 0, 3, -2 };
|
|
|
|
// AFTER: Pieces spawn within grid
|
|
cur = Piece{ bag.back(), 0, 3, 0 }; // Spawn at top of visible grid
|
|
nextPiece = Piece{ bag.back(), 0, 3, 0 };
|
|
```
|
|
|
|
#### Hold Function Updates:
|
|
```cpp
|
|
// BEFORE: Hold pieces reset above grid
|
|
hold.x = 3; hold.y = -2; hold.rot = 0;
|
|
cur.x = 3; cur.y = -2; cur.rot = 0;
|
|
|
|
// AFTER: Hold pieces reset within grid
|
|
hold.x = 3; hold.y = 0; hold.rot = 0; // Within grid boundaries
|
|
cur.x = 3; cur.y = 0; cur.rot = 0;
|
|
```
|
|
|
|
### 2. Font System Enhancement
|
|
|
|
**Goal**: Replace FreeSans font with PressStart2P for authentic retro gaming experience
|
|
|
|
#### Updated UI Elements:
|
|
- **Next Piece Preview**: "NEXT" label
|
|
- **Statistics Panel**: "BLOCKS" header and piece counts
|
|
- **Score Panel**: "SCORE", "LINES", "LEVEL" headers and values
|
|
- **Progress Indicators**: "NEXT LVL" and line count
|
|
- **Time Display**: "TIME" header and timer
|
|
- **Hold System**: "HOLD" label
|
|
- **Pause Screen**: "PAUSED" text and resume instructions
|
|
|
|
#### Font Scale Adjustments:
|
|
```cpp
|
|
// Optimized scales for PressStart2P readability
|
|
Headers (SCORE, LINES, etc.): 1.0f scale
|
|
Values (numbers, counts): 0.8f scale
|
|
Small labels: 0.7f scale
|
|
Pause text: 2.0f scale
|
|
```
|
|
|
|
#### Before vs After:
|
|
```
|
|
BEFORE (FreeSans): AFTER (PressStart2P):
|
|
┌─────────────────┐ ┌─────────────────┐
|
|
│ SCORE │ │ SCORE │ ← Retro pixel font
|
|
│ 12,400 │ │ 12,400 │ ← Monospace numbers
|
|
│ LINES │ │ LINES │ ← Consistent styling
|
|
│ 042 │ │ 042 │ ← Authentic feel
|
|
└─────────────────┘ └─────────────────┘
|
|
```
|
|
|
|
## Technical Benefits
|
|
|
|
### 1. Standard Tetris Behavior
|
|
- **Proper Spawning**: Pieces now appear at the standard Tetris spawn position
|
|
- **Visible Entry**: Players can see pieces entering the game area
|
|
- **Collision Detection**: Improved accuracy for top-of-grid scenarios
|
|
- **Game Over Logic**: Clearer indication when pieces can't spawn
|
|
|
|
### 2. Enhanced Visual Consistency
|
|
- **Unified Typography**: All gameplay elements use the same retro font
|
|
- **Authentic Aesthetics**: Matches classic arcade Tetris appearance
|
|
- **Professional Polish**: Consistent branding throughout the game
|
|
- **Improved Readability**: Monospace numbers for better score tracking
|
|
|
|
### 3. Gameplay Improvements
|
|
- **Predictable Spawning**: Pieces always appear in the expected location
|
|
- **Strategic Planning**: Players can plan for pieces entering at the top
|
|
- **Reduced Confusion**: No more pieces appearing from above the visible area
|
|
- **Standard Experience**: Matches expectations from other Tetris games
|
|
|
|
## Implementation Details
|
|
|
|
### Spawn Position Logic
|
|
```cpp
|
|
// Standard Tetris spawning behavior:
|
|
// - X position: 3 (center of 10-wide grid)
|
|
// - Y position: 0 (top row of visible grid)
|
|
// - Rotation: 0 (default orientation)
|
|
|
|
Piece newPiece = { pieceType, 0, 3, 0 };
|
|
```
|
|
|
|
### Font Rendering Optimization
|
|
```cpp
|
|
// Consistent retro UI with optimized scales
|
|
pixelFont.draw(renderer, x, y, "SCORE", 1.0f, goldColor); // Headers
|
|
pixelFont.draw(renderer, x, y, "12400", 0.8f, whiteColor); // Values
|
|
pixelFont.draw(renderer, x, y, "5 LINES", 0.7f, whiteColor); // Details
|
|
```
|
|
|
