Sprite Sheets that are not Uniform

[DylanD]

Hello again everyone!

I was wondering if there was a way to get all the sprites in a sprite sheet automatically like they do here http://doc.babylonjs.com/babylon101/sprites but with sprites that are not uniform size (cellSize is not uniform).  I know I could manually do it but I have many sprites and that could be very time consuming, and very messy.

So I'm hoping there is a way to have sprite manager automatically make the cells.  

Any ideas?

not without a json mapping or something of the sprites, something needs to tell where each sprite start & end  
uniform sprite sheets can be done like that because you just add the sprite size each time you need to find the next one.

Starting with Babylon.js v2.1, you can define sprite's width and height:

player.width = 0.3; player.height = 0.4;

You can also directly define manager.cellWidth and manager.cellHeight

Oh i thought you ment a spritesheet where different sprites have different sizes? 
like there might be a man 100x100 and then a tree 100x200

How could I do a json mapping ?

I have tried this but its all manual...

 

Thanks for the response though.

often, spritesheet editing/creation tools have json exports.. (they map the sprites as you add them to the sheet)

but i don't think you can automaticly create them from an already finished spritesheet,
it simply would have no way of telling where one starts and the next ends.

oh.  A .png.meta file wouldn't have this information would it?

I don't know, sorry, but sounds like it might be worth researching.
i hope you figured it out
