shinkan The new version has just been submitted for review and will be available very soon.
The new version (1.2) has full support for the C3 runtime, it is backward compatible, and has been submitted to lots of tests to make sure it works perfectly on C2, C3 with the C2 runtime, and C3 with the C3 runtime.
The manual has been almost completely re-written with a more "to the point" approach. It explains how to implement energy system features commonly found in a lot of games. It has a step-by-step guide to implementing a health and mana systems, with point regeneration over time.
On a more personal note ...
Over the course of the last two years, I've dived deep into one of the most powerful Unity assets ever made: UFPS, I was pleased to see that it uses an energy system almost similar to Health. However, I felt that Health on Construct was still more powerful than anything I've seen on Unity. Words can't explain it, but if you've experienced both, you'll know what I'm talking about.
Maybe it has to do with the ability to have multiple instances of Health in your sprites and repurpose them to create any energy system imaginable, coupled with the powerful event sheets of Construct. It's definitely quicker and more intuitive.
I've already received quite some feedback by email, in this forum thread, and in the form of reviews, yet it's always great to hear the opinion of other people, so if you have any feedback or feature request, don't hesitate to share it. I'm always looking for opportunities to take my addons to the next level.
