Create Animated Widgets with nfsDigitalClock3D — Step-by-Step GuidenfsDigitalClock3D is a popular mod component used in racing game HUDs and custom dashboards to display time, lap timers, and other dynamic information with eye-catching 3D effects. This guide will walk you through creating animated widgets using nfsDigitalClock3D, from installation to advanced animation techniques, so you can build polished, performant, and visually engaging widgets for your game or mod project.
What you’ll learn
- How to install and set up nfsDigitalClock3D
- Basics of the widget structure and assets
- Creating a simple animated clock widget
- Advanced animations: easing, keyframes, and layered effects
- Performance tips and troubleshooting
- Example widget project with code snippets
Prerequisites
- Basic familiarity with modding the target game (file structure, asset import)
- Simple scripting knowledge (Lua, JavaScript, or the mod’s supported language)
- Tools: a text editor (VS Code/Notepad++), image editor (Photoshop/GIMP), and a 3D/texture viewer if needed
Installation and setup
- Download the nfsDigitalClock3D files and any required dependencies from the mod repository or community release.
- Unpack the archive into your game’s mod folder (follow the mod’s README for exact paths).
- Verify that the base assets (font textures, sprite sheets, shader files) are present.
- Launch the game and check the console or log for any shader/asset errors.
If the mod provides a config file for widget registration, open it and add a new entry for your widget (name, path to assets, and initial parameters).
Understanding the widget structure
A typical nfsDigitalClock3D widget contains:
- A main configuration file — defines behavior, update rate, and bindings.
- Visual assets — textures for digits, icons, background panels.
- Animation scripts — keyframes, easing settings, and events.
- Shader/material files — control 3D effects like extrusion, glow, and lighting.
File names and formats vary by mod version; common formats include .ini/.cfg for configs, .png for textures, and .fx/.shader for materials.
Creating a simple animated clock widget
Step 1 — Create visuals
- Make a 256×64 or 512×128 PNG sprite containing digit textures (0–9) arranged in a grid, plus colon and any icons.
- Export the image with transparency and name it clock_digits.png.
Step 2 — Configuration
Create a config file (example: clock_widget.cfg) with basic settings:
- Position on screen (x, y)
- Scale
- Update frequency (e.g., 60 Hz)
- Bindings to in-game time or a script variable
Example structure (pseudo-format):
[widget] name = "SimpleClock" x = 400 y = 50 scale = 1.0 update_rate = 60 digits_texture = "clock_digits.png" Step 3 — Basic animation (fade-in)
Implement a simple fade-in using a script or the widget’s animation section:
- At spawn time t=0: opacity = 0
- Over 0.5s: opacity -> 1 (linear or eased)
Pseudo-keyframe:
[keyframes] 0.0 = opacity:0 0.5 = opacity:1 Step 4 — Hook up time updates
Use the mod’s scripting API to read the in-game clock or elapsed time and map each digit to the corresponding sprite cell. Update the displayed digits every second (or every frame for smoother effects).
Advanced animations
Layered 3D extrusion and glow
- Use the shader/material file to create an extrusion effect: duplicate the digit mesh, offset along z-axis, and shade darker to simulate depth.
- Add a glow pass by rendering an additive blurred version of the digit on top.
Smooth digit transitions (rolling effect)
Instead of snapping between digits, animate a vertical offset between sprite rows to create a rolling odometer effect:
- When a digit increments, animate its UV offset from row N to row N+1 over 0.2–0.4s with easing (easeOutCubic works well).
Easing and timing
Common easing functions:
- Linear — constant speed
- EaseIn — slow start
- EaseOut — slow end
- EaseInOut — smooth in and out
For natural UI motion, prefer easeOutCubic or easeInOutSine for most transitions.
Compound animations (bounce + settle)
Combine scale and position tweens:
- Scale up to 1.1 over 0.12s (easeOut)
- Scale down to 0.95 over 0.1s (easeInOut)
- Settle at 1.0 over 0.08s
This gives a satisfying “button press” feel for lap completions or notifications.
Scripting examples
Example pseudo-code for digit rolling (replace with mod’s scripting language):
function setDigit(widget, index, newValue) local current = widget.digits[index].value if newValue == current then return end local startRow = current local endRow = newValue -- animate UV offset from startRow to endRow over 0.25s animate(widget.digits[index], "uvOffsetY", startRow, endRow, 0.25, easeOutCubic) widget.digits[index].value = newValue end Example pseudo-code for glow pulse on lap completion:
function onLapComplete() animate(widget.glow, "opacity", 0, 1, 0.12, easeOut) animate(widget.glow, "opacity", 1, 0, 0.4, easeIn) end Performance tips
- Bake as much as possible into textures (animated sprites) rather than heavy runtime geometry.
- Use texture atlases to reduce draw calls.
- Avoid high-frequency updates for non-critical elements — update digits once per second unless smooth animation is required.
- Keep shader complexity reasonable; expensive post-processing hurts frame rate.
- Test on lower-end hardware to balance visuals vs. performance.
Troubleshooting
- Missing textures/shader errors: check paths in config and ensure filenames match exactly (case-sensitive on some systems).
- Flickering: ensure z-order and depth settings are correct for 3D extrusion layers.
- Jittery animation: verify update frequency vs. animation durations; prefer frame-based delta time for consistent timing.
- High CPU/GPU: reduce update rate, simplify shaders, combine quads into atlases.
Example project: “NeonLapClock”
Files:
- neon_lap_clock.cfg — widget config (position, scale, textures)
- clock_digits.png — digit atlas (0–9, colon)
- neon_material.shader — extrusion + glow
- animations.lua — easing/keyframes and event hooks
Key behaviors:
- Rolling digits for seconds
- Glow pulse on lap complete
- Slight tilt and parallax when vehicle turns (bind to yaw rate)
Final notes
Design animated widgets with clarity and feedback in mind: animations should enhance information delivery, not distract. Start simple, iterate with player testing, and profile performance early.
If you want, I can generate a complete example package (config, shader, textures layout, and scripts) tailored to your target game/mod format — tell me which game/mod system you’re using and which scripting language it supports.
