If you are working with Pixi.js and wish to add text input functionality to your projects, the PIXI TextInput plugin is your go-to solution. This plugin seamlessly integrates HTML input elements into your Pixi.js stage, providing a flexible and user-friendly way to manage text input. Let’s dive into the steps to get you started!

Getting Started with PIXI TextInput

Follow these simple steps to install and create a text input box with the PIXI TextInput plugin.

Step 1: Installation

To begin, ensure you have Pixi.js installed, and then run the following command to install the PIXI TextInput plugin:

shnpm install pixi-text-input

Step 2: Creating an Instance

After installation, you can create an instance of the TextInput. Here’s how:

import TextInput from 'pixi-text-input';

let input = new TextInput({
  input: {
    fontSize: '25pt', 
    padding: '14px', 
    width: '500px', 
    color: '#26272E',
  },
  box: {
    fill: 0xE8E9F3, 
    rounded: 16, 
    stroke: {
      color: 0xCBCEE0, 
      width: 4
    },
  }
});

Understanding the Code through an Analogy

Imagine you are setting up a cozy café. The HTML input element acts as your café’s welcoming counter where customers can place their orders. The PIXI TextInput functions like the decorative design of that counter:

• The **input** properties (fontSize, padding, width) reflect the aesthetics of your counter.
• The **box** configuration (fill, rounded, stroke) determines the physical appearance of the counter, i.e., its color, shape, and outline.

Just as you customize your café to enhance customer experience, you can style the PIXI TextInput to fit the design of your project!

Styling Your TextInput

You can easily style the PIXI TextInput using CSS styles, ensuring it blends with your project’s theme.

let input = new TextInput({
  input: {
    fontSize: '25pt',
    padding: '14px',
    width: '500px',
    color: '#26272E',
  },
  box: {
    // Box configuration here
  }
});

For example, update the thickness of the border, the background color, or even the font size directly.

Box Customization

Using the default box generator, you can customize the appearance of the text box in three states: DEFAULT, FOCUSED, and DISABLED. Here’s a simple config:

let input = new TextInput({
  input: { /* input styles */ },
  box: {
    default: {
      fill: 0xE8E9F3, 
      rounded: 16, 
      stroke: {
        color: 0xCBCEE0, 
        width: 4,
      },
    },
    focused: {
      fill: 0xE1E3EE, 
      rounded: 16, 
      stroke: {
        color: 0xABAFC6, 
        width: 4,
      },
    },
    disabled: {
      fill: 0xDBDBDB, 
      rounded: 16
    }
  }
});

This allows you to produce visually appealing input fields that react to user interactions.

Troubleshooting Common Issues

As you integrate the PIXI TextInput plugin into your projects, you may encounter some small bumps. Here’s how to navigate through common issues:

• Text not displaying: Ensure your input styles are correctly defined. Double-check your CSS properties.
• Box not rendering: If the box doesn’t appear, verify that you’re passing the box style correctly in your constructor.
• Focus issues: If focusing doesn’t work, confirm if the input element is correctly added to the stage.
