I'm trying to get a dynamic rendering order going in ocanvas but can't find any information in the docs about how to go about doing it. I want something along the lines of "the object's y position affects the order in which it is rendered", it's for an isometric game engine. Any help would be greatly appreciated.

thanks

There's nothing automatic for this, but you can probably implement it quite easily with the zIndex property: http://ocanvas.org/docs/Display-Objects/Base#property-zIndex

  • Hi Johannes, I tried that but it didn't work. I tried making the zindex of the object equal to its y position. perhaps I'm not using it correctly? – Jeff May 21 '15 at 07:51
  • it seems that no matter what they are rendered in the order they are added to the canvas – Jeff May 21 '15 at 07:57
  • The `zIndex` property is a real index for the object in the list of children for its parent, which means you can't use the `y` value directly, but you can convert it to get the index you want. I made an example here (drag around the rectangles to try it): http://jsfiddle.net/ky3z7mjg/ – Johannes Koggdal May 21 '15 at 23:00
