Author: Rex
Arcade behavior of game object

Usage¶

Install plugin¶

Load minify file¶

Enable arcade physics engine in configuration of game

var config = {
    // ...
    physics: {
        default: 'arcade',
        arcade: {
            // debug: true
        }
    }
}
var game = new Phaser.Game(config);

Load plugin (minify file) in preload stage

scene.load.plugin('rexbulletplugin', 'https://raw.githubusercontent.com/rexrainbow/phaser3-rex-notes/master/dist/rexbulletplugin.min.js', true);

Add bullet behavior

var bullet = scene.plugins.get('rexbulletplugin').add(gameObject, config);

Import plugin¶

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

Enable arcade physics engine and install plugin in configuration of game

import BulletPlugin from 'phaser3-rex-plugins/plugins/bullet-plugin.js';
var config = {
    physics: {
        default: 'arcade',
        arcade: {
            // debug: true
        }
    },
    // ...
    plugins: {
        global: [{
            key: 'rexBullet',
            plugin: BulletPlugin,
            start: true
        },
        // ...
        ]
    }
    // ...
};
var game = new Phaser.Game(config);

Add bullet behavior

var bullet = scene.plugins.get('rexBullet').add(gameObject, config);

Import class¶

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

Enable arcade physics engine in configuration of game

var config = {
    // ...
    physics: {
        default: 'arcade',
        arcade: {
            // debug: true
        }
    }
}
var game = new Phaser.Game(config);

Import class

import Bullet from 'phaser3-rex-plugins/plugins/bullet.js';

Add bullet behavior

var bullet = new Bullet(gameObject, config);

Create instance¶

var bullet = scene.plugins.get('rexBullet').add(gameObject, {
    speed: 200,
    // wrap: false,
    // padding: 0,
    // enable: true,

    // angle: undefined,
    // rotation: undefined
});

speed : moving speed, pixels in second.
Wrap
- wrap : Set true to enable wrap mode. Default value is false.
- padding
enable : set false to disable moving.
angle, rotation :
- undefined : Use angle of game object as angle of bullet. Default value.
- A number : Angle of bullet, in degrees or radians.

Speed¶

Set

bullet.setSpeed(speed);
// bullet.speed = speed;

Get
```
var speed = bullet.speed;
```

Set wrap mode¶

bullet.setWrapMode(wrap, padding);

wrap : Set true to enable wrap mode.

Angle¶

Set angle

bullet.setAngle(degrees);
// bullet.angle = degrees;

or

bullet.setRotation(radians);
// bullet.rotation  = radians;

Use angle of game object

bullet.setAngle();
// bullet.setRotation();
