};
var game = new Phaser.Game(config);

Create instance

var recorder = scene.plugins.get('rexTCRP').addRecorder(scene);

Import class¶

Install rex plugins from npm
```
npm i phaser3-rex-plugins
```

Import class

import TCRP from 'phaser3-rex-plugins/plugins/arcadetcrp.js';

Create instance

var recorder = new TCRP.Recorder(scene);

Create instance¶

var recorder = scene.plugins.get('rexTCRP').addRecorder(scene);

Start recording¶

recorder.start();
// recorder.start(startAt);  // start-at in step-count

Push commands¶

recorder.addCommand([fnName, param0, param1, ...]);
// recorder.addCommand([command0, command1, ...]);
// recorder.addCommand([fnName, param0, param1, ...], offset);  // time-offset in step-count

Get commands¶

var commands = recorder.getCommands();        // Get a shallow copy of commands
// var commands = recorder.getCommands(true); // Get reference of commands

Format of return commands:

[
    [time, [command]],
    [time, [command0,command1]],
    ...
]

time : Time in step-count

Pause, Resume, stop recording¶

recorder.pause();
recorder.resume();
recorder.stop();

Seek elapsed time¶

recorder.seek(time);   // elapsed time in step-count

State of recorder¶

var isRecording = recorder.isRecording;
var now = recorder.now;

now : Now time in step-count.

Time-scale¶

Set

recorder.setTimeScale(value);
// recorder.timeScale = value;

timeScale : An integer equal or larger than 1

Get
```
var timeScale = recorder.timeScale;
