Creating sprite from texture

[jSwtch]

Hello,

I have seen different methods for creating a sprite from a texture. Is there a difference?

I am mainly looking at PIXI.Texture.fromImage(... vs renderer.generateTexture(...

sprite = new PIXI.Sprite(
 new PIXI.Texture.fromImage(
  "...img/path"
  )
);
app.stage.addChild(sprite);

let texture: PIXI.Texture = renderer.generateTexture("...img/path");
let sprite: PIXI.Sprite = new PIXI.Sprite(texture);
stage.addChild(sprite);

Also for particle emitters is it better to use sprites or textures?

 

I see that (https://github.com/pixijs/pixi.js/wiki/v4-Performance-Tips? "textures are automatically managed by a Texture Garbage Collector".

However most examples of particle emitters I see seem to use sprites.

 

Edit: I see that sprites are textures

generateTexture doesn't take a string. It takes a DisplayObject and creates a texture from rendering the object.

Also, PIXI.Texture.fromImage is a function not a constructor. Don't call it with new. You should either do `new PIXI.Texture()` or `PIXI.Texture.fromImage()`, don't combine them.

Textures don't render, sprites do. Textures are just images, sprites combine images (textures) with a transform to make it renderable.

I bet all of them do, because you can't render a texture because it isn't a DisplayObject.

They are not. Sprites are DisplayObjects, and they contain a reference to a Texture. Textures are a standalone object that cannot be rendered.
