Understanding Drawing Accuracy & Vector Alignment
Our drawing engine uses a custom vector comparison model to calculate drawing accuracy in real-time. This guide details how scores are calculated.
Vector Coordinates Checking
When you draw on the canvas, the game captures coordinate data points along your stroke. These points are matched against the mathematical target shape vector database:
1. **Path Alignment**: The engine evaluates the distance between your drawn points and the target outline. 2. **Stroke Uniformity**: Checks if the stroke is completed in a single fluid gesture or multiple segments. 3. **Proportion Calibration**: Normalizes scale variations, checking if proportions are correct even if the drawing is slightly larger or smaller.
Scoring Thresholds
- **Great**: 70% to 89% accuracy. Awards standard Coins.
- **Perfect**: 90% or higher. Awards bonus Gems and unlocks premium cosmetic rewards.
Scoring Tips
To achieve perfect ratings, draw steadily without lifting your finger mid-stroke. Lifting your finger concludes the stroke segment and triggers immediate vector comparisons.
