Dynamic HUD Formatting
This page documents the dynamic string formatting engine used by Speedometer to eliminate HUD jitter and text box resizing issues.
📊 Formatting Specification Infobox
| Property | Details |
|---|---|
| Locale System | Locale.ROOT (Guarantees . decimal separator worldwide) |
| Format Specifier | %.2f (Dynamic floating point conversion) |
| Legacy Rigid Pattern (Banned) | %6.2f (Fixed 6-char width with space padding) |
| Current Pattern | String.format(Locale.ROOT, "Speed: %.2f b/s (H: %.2f, V: %.2f)", targetSpeed, targetHoriz, targetVert) |
🛠 Solving String Jitter & Padding Issues
Legacy Fixed Width Bug (%6.2f)
In early iterations, fixed-width string specifiers like %6.2f produced rigid space padding:
text
"Speed: 4.30 b/s (H: 4.30, V: 0.00)" <-- Unnecessary space gapsThis caused F3 debug text boxes to twitch and jump whenever speed shifted between single, double, and triple digits.
Modern Dynamic Specifier (%.2f)
By adopting unpadded floating point specifiers (%.2f) evaluated under Locale.ROOT, Speedometer produces clean, dynamic text output:
text
"Speed: 4.30 b/s (H: 4.30, V: 0.00)"
"Speed: 70.00 b/s (H: 70.00, V: 0.00)"This ensures smooth text box resizing, zero horizontal jitter, and consistent decimal separation regardless of system language settings.
