A RenderTexture is a special texture that allows any pixi displayObject to be rendered to it.

__Hint__: All DisplayObjects (exmpl. Sprites) that render on RenderTexture should be preloaded.
|
|
Otherwise black rectangles will be drawn instead.
|
|
|
|
RenderTexture takes snapshot of DisplayObject passed to render method. If DisplayObject is passed to render method, position and rotation of it will be ignored. For example:
|
|
|
|
var renderTexture = new PIXI.RenderTexture(800, 600);
|

var sprite = PIXI.Sprite.fromImage("spinObj_01.png");

sprite.anchor.x = 0.5;
|
|
sprite.anchor.y = 0.5;
|
|
renderTexture.render(sprite);
|
|
|
|
Sprite in this case will be rendered to 0,0 position. To render this sprite at center DisplayObjectContainer should be used:
|
|
|
|
var doc = new PIXI.DisplayObjectContainer();
|
|
doc.addChild(sprite);

renderTexture.render(doc); // Renders to center of renderTexture
