Unity vs. HL2:ep2 mod(s)

[Psy]

EDIT: something else: how are ingame-interfaces? Like an inventory of sorts.

Pretty easy to implement but Unity GUI is a bit of a pain to work with at the moment. Thankfully, they're implementing a new system in the next version that will have an in-editor GUI for building instead of having to build every user interface in code.

We’re rewriting the in-game GUI system from the ground. We’ve made it simple and intuitive to create modern game interfaces with tons of animations and other effects. Everything is assembled in a visual GUI editor. A lot of effort is going into optimizing the GUI system for minimizing run-time overhead through automatic texture atlases and aggressive coverage-based batching.
