react-native-unity2's Introduction

react-native-unity2

NPM package NPM downloads License: MIT

Embed Unity content in your React Native app!

  • Succesfully tested with Unity 2022.x, 2021.x and 2020.x on Android and iOS.

  • Includes a complete, pre-configured Unity project and an example app.

  • The example app works on machines without Unity installed.

This module started out as a fork of react-native-unity-play, but is more or less rewritten with new and improved message passing (C# <=> TypeScript), fixing glitches and stability issues, and adding Swift support. That module was forked from other modules also, so kudos to all creators! ๐Ÿคฉ

Install

npm install react-native-unity2

Usage

RNUnity running on Android device

import React from "react"
import {Button, View} from "react-native"
import {UnityModule, UnityView} from "react-native-unity2"

export default function App() {
  return (
    <UnityView
      style={{flex: 1, justifyContent: "flex-end"}}
      onMessage={onMessage}
      onReady={onReady}
      keepAwake={true}>
      <View
        style={{
          flexDirection: "row",
          alignContent: "space-between",
          justifyContent: "center",
        }}>
        <Button
          title={"setColor"}
          onPress={async () =>
            console.log(await cubeApi.setColor(randomColor()))
          }
        />
        <Button
          title={"toggleRotate"}
          onPress={async () => console.log(await cubeApi.toggleRotate())}
        />
        <Button
          title={"getAccount"}
          onPress={async () => console.log(await cubeApi.getAccount())}
        />
        <Button
          title={"fail"}
          onPress={async () => console.log(await cubeApi.fail())}
        />
      </View>
    </UnityView>
  )
}

const onMessage = (data: any) => {
  console.log("Unity message: " + data)
}

const onReady = () => {
  console.log("Ready!")
}

const cubeApi = {
  setColor(color: string) {
    return UnityModule.callMethod("Cube", "setColorRN", color)
  },

  toggleRotate() {
    return UnityModule.callMethod("Cube", "toggleRotateRN")
  },

  getAccount() {
    return UnityModule.callMethod("Cube", "getAccountRN")
  },

  fail() {
    return UnityModule.callMethod("Cube", "failRN")
  },
}

const randomColor = () => {
  return `#${Math.floor(Math.random() * 16777215)
    .toString(16)
    .padStart(6, "0")}`
}
