I've sort of involuntarily started a project series that I thought I would share with anyone interested. I call it "Tutorials extended" and It's the result of various Unity tutorials, mainly official ones, after I've added the features I wanted to them.
My interest with Unity, and most other things, comes and goes very rapidly. And after a long period way Unity can be quite intimidating so I need something to ease me back into it. Tutorials accomplish this quite well. Mindlessly following a tutorial gradually reintroduces me to the tools again without it being overwhelming. And I may even end up learning something new as well. While following the tutorial I think about features I would like to add to that particular project and after I've completed the tutorial I just continue working on the project until I'm happy with what I have. The ultimate goal is rekindled interest in continuing with one of my own projects, all which suffer from feature creep.
First out in this series is the official Surivial Shooter tutorial from Unite training day 2014. You can play my version of it here: http://twiik.net/projects/survival-shooter-extended. There's also a link there for you to download the entire project if you so wish. When I read about the new GUI features in Unity 4.6 I wanted to try them out and this was also a nice tutorial to get me back into Unity after a long period of absence. Among the changes I've made are different enemy types with different behaviors, enemies now come at you in waves, there are power-ups, as well as numerous other tweaks to effects etc.
If you know of any cool tutorial projects you'd like to see extra features in just let me now and I'll see if they peak my interest. I have some other tutorial projects already laying around here. I'll upload those when I have cleaned them up a bit.
