What's the best UI layout tool you've ever used in a game engine, and why?
-
Ok thanks that makes sense, but I was more thinking about layout tools. E.g Unity has tools to let you anchor UI elements to various things and create groupings. I'm thinking about next steps for our system to enable more complex UIs to be made.
Not sure about layout tools themselves, but capability-wise, but relative anchoring is one of the things that I put into our UI system from the get-go, as it's really wildly convenient. Each UI element has an 'anchor' and a 'justify' parameter.

The Anchor param is a vector typically (but not limited to) 0,0..1,1 which defines the point on the element's parent, from BL to TR, which will be the origin point for the sub-element. Justify is the same, but defines the origin point on the sub-element itself.

So if I have two boxes, one being the child element of the other, and I want Box2's left side to be pinned to the right side of Box1, I would do something like: hud::set_anchor(&box2, vector2(1.0f, 0.5f)); hud::set_justify(&box2, vector2(0.0f, 0.5f));
