set graphics transform.worldTransform

i create a pixi.graphics. how to set transform.worldTransform of graphics ,

[ivan.popelyshev]

Why do you need it? There's "transform.decompose(matrix)" method

[fengFanYong]

because i want to set context.setTransform(1,1,1,1,0,0) of graphics

@ivan.popelyshev How to set context.setTransform(1,1,1,1,0,0) of graphics when render graphics?

Thank!

ok, so we have "graphics.transform" which is actually a combined "graphics.position", "graphics.scale", "graphics.rotation" and so on. But you can set them from matrix directly.

 

var matrix = new PIXI.Matrix();
matrix.set(1,1,1,1,0,0);

graphics.transform.setFromMatrix(matrix);

I DO NOT ADVICE TO USE (1,1,1,1), because that's actually a very bad matrix. Where did you take those parameters?

 When i create a sprite,it children is graphics,but i hope this position of graphics is a Actual pixel。

    var sp = new PIXI.Sprite();
    sp.x = 100;
    sp.y = 100;
    sp.width = 100;
    sp.height = 100;
    var g = new PIXI.Graphics();
    g.beginFill(0x123123);
    g.drawRect(0,0,100,100);
    g.endFill();
    sp.addChild(g);

 i hope draw a circle 100*100 pixel.

THANK!

if you have a circle with center (50,50), position of graphics is (100,100) and position of the parent sprite is (200, 200) , then, as a result, center will be shown at (350, 350).

There's no way to change that in pixi: graphics coordinates are multilied by graphics matrix and then by parent sprite matrix.
