Hi

I’m a little confuse why the example, particularly the emit from zone does not pass in any arguments and works with latest phaser build but when i have them in my code, it asks for 3 parameters. count, x and y.

[https://labs.phaser.io/edit.html?src=src/game%20objects/particle%20emitter/emit%20from%20shape.js&v=3.55.2](https://labs.phaser.io/edit.html?src=src/game%20objects/particle%20emitter/emit%20from%20shape.js&v=3.55.2)

Hi Samme,

The function itself requires 3 arguments - [phaser/ParticleEmitter.js at v3.55.2 · photonstorm/phaser · GitHub](https://github.com/photonstorm/phaser/blob/v3.55.2/src/gameobjects/particles/ParticleEmitter.js#L1873-L1878)

But the example emit from shape doesn’t pass any argument - [Phaser 3 Examples](https://labs.phaser.io/edit.html?src=src/game%20objects/particle%20emitter/emit%20from%20shape.js&v=3.55.2)

I’m trying to copy over the example to my own code and I’m not able to because of the required arguments.

All of the `explode()` arguments are optional, in fact.
