react-umg's Introduction

React-UMG ·

This repository is a fork of react-umg whose original author is Wolfgang Steiner

A React renderer for Unreal Motion Graphics (https://docs.unrealengine.com/latest/INT/Engine/UMG/)

This project is dependent on Unreal.js

Link to Demo

We recommend using React with Babel to let you use JSX in your Javascript code. JSX is an extension to the Javascript language that works nicely with React.

Install

To install React-UMG with npm, run:

npm i --save react-umg

Web-dev like Component Naming

div(UVerticalBox)
span(UHorizontalBox)
text(UTextBlock)
img(UImage)
input(EditableText)

Example

Create Component

class MyComponent extends React.Component {
    constructor(props, context) {
        super(props, context);
        this.state = {text:"MyComponent"};
    }

    OnTextChanged(value) {
        this.setState({text: value});
    }

    render() {
        return (
            <div>
                <uEditableTextBox Text={this.state.text} OnTextChanged={value=> this.OnTextChanged(value)}/>
                <text Text={this.state.text}/>
            </div>
        )
    }
}

Draw With React-UMG

let widget = ReactUMG.wrap(<MyComponent/>);
widget.AddToViewport();
return () => {
    widget.RemoveFromViewport();
}

more and more people like to use typescript ,
Will typescript's version be released ?

TypeError: Cannot read property 'Add' of undefined

I'm using Unreal.js zThirdPerson.js example. It runs perfect and smooth.
When I run the following code snipped from React-UMG documentation.

const React = require('react');
const ReactUMG = require('react-umg');

class MyComponent extends React.Component {
  constructor(props, context) {
    super(props, context);

    this.state = {
      text: 'MyComponent',
    };
  }

  OnTextChanged(value) {
    this.setState({
      text: value,
    });
  }

  static attach() {
    this.widget = ReactUMG.wrap(<MyComponent />);
    this.widget.AddToViewport();

    return () => {
      this.widget.RemoveFromViewport();
    };
  }

  render() {
    return (
      <div>
        <uEditableTextBox
          Text={this.state.text}
          OnTextChanged={value => this.OnTextChanged(value)} />
        <text Text={this.state.text} />
      </div>
    );
  }
}

MyComponent.attach();

I get the following error.

Error: Game/Content/Scripts/node_modules/react-umg/src/ReactUMGMount.js:146: TypeError: Cannot read property 'Add' of undefined
Error: TypeError: Cannot read property 'Add' of undefined
Error:     at Object.render (Game/Content/Scripts/node_modules/react-umg/src/ReactUMGMount.js:146:26)
Error:     at Function.attach (Game/Content/Scripts/components/MyComponent.js:36:38)

I pushed a PR to fix this error.

Thanks

How to debug this stuff?

Hi guys, I am exited to see react integration for unreal4. I want to help with development. How do you debug this stuff?

Can I use css?

Can I use styled-components for styling?
