[PIXI] What's the uvs option?

[d13]

I noticed that one of the options for a ParticalContainer is `uvs`

 

Does anyone know what `uvs` is, and what would setting it to `true` do?

 

Thanks!!

The `uvs` are like normalized positons into the texture to be rendered. IF you are using different particles from a sprite sheet, the different particles will have different uvs so you will need to set it to true.

Ok, so if I use a 3 particles from the same sprite sheet (say a bunny, a frog and a kangaroo), I would need to set `uvs` to true?

If you want to change bunny into frog "on the fly" without creating new sprite, yes. For example, if you are creating fireworks with green, red and yellow rockets, and just using same 100 sprites for the entire course of animation as recommended (just changing their frames as they "expire"). 

 

If you need to just create a bunny, a frog and a kangaroo - no. All attributes will be loaded initially (and whenever list of children is updated).
