Release 0.9.0 – Introduction of Layer Bolts

I thought I’d start making a blog post for each release to highlight some of the updates. It’s been almost a month since the last release because I made a lot of deep changes. Unfortunately that means this version is incompatible with older versions. In these early days that’s going to happen from time to time.

Layer Bolts

The biggest new feature is called Layer Bolts. The name comes from the fact that they bolt on functionality to layers. In this initial release all the bolts are layout related, but in future versions they could add interactivity or change how layers are rendered or any number of things.

Bolts appear next to the layer in the layer manager. Clicking on the icon loads the node parameters in the editor

So what do bolts do? Right now they mostly do layout. There’s an align bolt that keeps a layer aligned to either its parent or the scene. The linear layout bolt will position and space each child equally. The padding bolt is used to add padding that will be factored in when being laid out.

Spacebar Quick Menu

Pressing and releasing the spacebar without moving the mouse will now popup a menu for quickly searching for nodes to add to your scene. In the future this menu will gain context dependent options, but it’s a start.

Graph Editor Changes

In my ongoing quest to improve the usability of the graph editor I’ve made some major changes. The biggest change is that the graph editor now only shows the nodes of the selected layers. This is to try and keep the editor clean when there are lots of nodes in a scene. Each layer is represented by a column in the graph editor. Nodes can be added to various layers by right clicking within the column. Columns will also resize according to the contents. This is still very much a work-in-progress so expect more changes in the future.
