How can i control TexturePack with rotation

[GBear]

hi. ivan.

 

this looks great..

 

but here looks one problem

 

i changed y coordinate to 0 from 50

 

and then  i can look image that has wrong position

 

http://jsfiddle.net/s7bj8y3x/12/

 

this is changed jsfiddle

 

 

it seems only third is wrong

 

thx

There are offsets for second and third, look at the atlas. For third image, 20 pixels were trimmed from above.

offset: 0, 2offset: 0, 20

hi.  anwser is late.. sorry..

hmm. 

 

yes but....it's wrong...

 

20 pixels were trimmed from above.. you right. but it's looks not 20 pixel..

 

this is right image when all trimmed image drawn

 

 

second and third don't have empty pixel..

but in this case it's not...!

 

thx..

Ok, now I understand how this needs to be trimmed, i'll fix it

[ivan.popelyshev]

Trim and rotation are working! Build latest pixi from github dev branch. This thing will work: 

var atlas = assets.animation.spineAtlas;
var textures = {};
for (var i=0; i<atlas.regions.length; i++) {
    var region = atlas.regions;
    var baseTexture = region.page.rendererObject;
    var frame = new PIXI.Rectangle(region.x, region.y, region.width, region.height);
    var crop = frame.clone();
    var trim = new PIXI.Rectangle(region.offsetX, region.originalHeight - region.height - region.offsetY, region.originalWidth, region.originalHeight);
    textures[region.name] = new PIXI.Texture(baseTexture, frame, crop, trim, region.rotate?6:0));
}

You can mark that as solution on this topic.

thx ivan.. always.. ^^/

Awesome.. 3.0.9 has your rotating system?

maybe it is  D4...

Is it good on canvas and webgl with pixi spine atlas when i set region.rotate to 6?

because i'm using own system to draw normal image 

if it is right i will update to new viersion. i;m using 3.0.8 now..
 

ps. 3.0.9 is a little bit slow than 3.0.8. i don't know correctly reason.. but i tested with my game and  example that only draw a lot of spine on scree

https://github.com/ivanpopelyshev/examples/blob/master/_site/js/pixi.js - I compiled it for you. Rotations are in latest commit, there is no official build for it yet.

UPD. I'll change the way how frame/crop/trim work soon. I'll notify you about it.

@ivan.popelyshev i see. thx....

ps> do you have plan to update pixi.spine?

[ivan.popelyshev]

Yeah, I'll update pixi-spine at the same time, and you wont have to write loading code for an atlas anymore. It will just work
