sprite.tilePosition values?

[sandbird]

I created a PIXI.TilingSprite based sprite and what I want to do is animation using image file with all the frames of the animation.

So... all I want to do is to shift the tiled image to the next frame to display.

Anyway, I found out that sprite.tilePosition.x and sprite.tilePosition.y excepting strange values and there is no documentation what unit sprite.tilePosition expecting.

 

Each of my "frames" are X = 1083, Y = 374.

I found out that I need to enter:

 

sprite.tilePosition.x = frame_x * -1637;

sprite.tilePosition.y = frame_y * -410;

 

It do working on Chorme, Firefox, IE on my Windows 8.1 in any resolution.

Since that pixi.js only working with web-gl under Windows 8.1 I don't know if it'll work also with Canvas mode.

Guess that I need to install XP to see how it'll work with canvas

 

Anyone know what unit sprite.tilePosition excepting?

 

BTW: I'm working with the github master version.
