Changing emitter textures

Recommended Posts

I have an emitter which when activated, it will take the texture from what it collided into for its effect animation.  I haven't been able to figure out how to change the texture of the emitter upon the event like I can with a sprite by calling .loadTexture, so I'm currently forced to create a new emitter each time (certainly don't want to be doing this!).

 

I saw the random sprite.js example for emitters,  but just couldn't figure out how to choose between the options rather than pick from them randomly.

 

Phaser example:

emitter.makeParticles(['diamond', 'carrot', 'star']);

My code (happens upon a collision event):

ballEmitter = this.game.add.emitter(200, 200 + (i * 16), 5);            ballEmitter.makeParticles(aCombo[0].key);

Thanks ahead of time for any help.  ^_^

You'll want to be careful with makeParticles, though, as it does exactly that: makes more particles. The existing ones in the emitter are not removed or overwritten, but left as dead.

 

You might be better off making an emitter per particle sprite you want to use, then calling start on the appropriate one when the collision event happens, adjusting the emitX and emitY values to match where the collision happened.

 

 

Emitters themselves do not have textures, they are just Phaser.Groups. They do not store the texture key you pass to makeParticles, they just use them when making the Sprites for the particles. You might be able to get away with

myEmitter.forEach (function(particle){ particle.loadTexture();}, this);

but I haven't tried that at all. The forEach function loops over a Phaser.Groups children - all the particles, in the case of an emitter, - and passes each one to the function you supply.

to change particle image via makeParticles() method you'll need to restart it, you can see the method, how we done it in our plugin

https://github.com/koreezgames/phaser-particle-editor - this is editor link, here you can create you emitter

https://github.com/koreezgames/phaser-particle-editor-plugin - this is plugin link, here are all emitter specific methods, so you can see how we do that (ES6)
