Bringing Numerical Values to Life with Particle Systems
Utilizing Unity's Particle System to Display In-Game Messages
In our game, The Unliving, we wanted to add a unique touch to in-game messages that display numerical values like damage, rewards, and health points. Instead of relying on Unity's UI system, we opted to use Particle Systems to customize the appearance and behavior of these messages, offering more dynamic possibilities.
Solution Strategy
For this quest, we employed shaders to display pre-prepared textures using accurate UV coordinates. This data was transmitted through two vertex streams to the Particle System using . Our approach involves using a single instance of the Particle System for each type of message, which boosts efficiency compared to using Unity UI.
How the Plan Unfolds
Creating the Texture and Data
For a seamless character set, we created to store the font symbols in the correct order. Using this structure, we developed the class, enabling us to spawn a particle with the desired position, value, color, and size by calling the method.
Particle Systems in Unity allow for transferring custom data in the form of two streams, . To maintain the integrity of the UV coordinates, we used two to convey the message length and UV-coordinates of the symbols. The structure of each allows for packing 24 single-digit numbers, enough to accommodate our messages up to 23 characters long.
Working the Particle Magic
Particle spawning is handled by the method of the class. When packing rows into two , you'll find that the completed vectors are ready to be used.
Shader Programming Power
Unity Editor Sorcery
We created a material and assigned our shader to it. In the scene, we added an object with the ParticleSystem component and the material. Then, we tweaked the particle behavior and disabled the feature. With the method at the ready, it's time to bring our message to life!
The Way Forward
Utilizing the power of Particle Systems can add a stunning visual aspect to numerical in-game messages, making them more engaging and immersive. Want to try out our approach? Head over to our game, The Unliving, where you can see this system in action!

The Inside Scoop:
Implementing numerical value messages using the Particle System in Unity offers an exciting mix of visual effects and information delivery, but it's essential to remember that Particle Systems are primarily used for visuals rather than textual messages. If you're looking to display numerical values with dynamic visuals, consider combining text rendering and particle effects. Here’s a step-by-step guide for that:
Taking Action
1. Text Rendering:
First, create a text renderer to display the numerical value using Unity's component.
2. Particle Effects:
Create a Particle System in Unity to generate visual effects around the text to enhance visual appeal.
3. Integration:
Combine the text renderer with the particle system to create a visually appealing message display.
4. Dynamic Updates:
Update the text content and particle effects dynamically based on game logic.
Methodology Breakdown:
- Setup:
- Create a text renderer ( component).
- Set up a Particle System for visual effects.
- Dynamic Updates:
- Update the text content and the particle system properties dynamically.
- Integration:
- Position the text in the center of the particle effect.
- Use scripts to synchronize updates between text and particles.
- Game Logic Integration:
- Tie the numerical value updates to game events or logic (e.g., score increases, health changes).
By following these steps, you can create a visually engaging in-game message display with both numerical values and dynamic particle effects in Unity!
- Leveraging the power of Particle Systems in Unity for visual effects can be combined with artificial-intelligence to create intelligent, dynamic, and interactive narrative elements within the game, The Unliving.
- As the gaming industry evolves, integration of artificial-intelligence and technology with gadgets like Particle Systems can lead to the creation of innovative, intelligent game interfaces, providing a more immersive and engaging gaming experience.
