DHMC Dev Diary 5/23/16 – AI Update

The original AI in DHMC was structured in a way that made things difficult to make it smarter and harder to predict. We decided a full rewrite of the AI was in order to address these issues.

We have chosen to use a couple of approaches to fix these issues. The first issue causing difficulty in the live implementation is the overall structure of the coding, which was very difficult and time consuming to implement new features. This has been replaced by something called a behavior tree. Behavior trees allow you to break up the AI into tasks, for instance a task to go from where the AI is standing to a position on the map somewhere. Then from there you can build a tree structure based on logic nodes and these tasks to create the AI. Not only does this allow for easy addition of new tasks the AI can perform, but it also simplifies making multiple types of AI (patrol, sentry, etc.) The other benefit this provides is we can create simplified trees that do certain things to test the parts before testing the whole tree.

The other issue of predictability we are working on is to create a maneuver system. You could think of this like plays in football. Basically the AI chooses a strategy when engaging in combat like a circle maneuver where it circles the target while firing at them. By creating a lot of these maneuvers for the AI to choose from, it can make the AI less predictable vs the current AI in live which always uses the same tactics.

These things form the basis for a simple AI like we had before, but gives the ability to add on more complex things like squad based AI. We will have more footage and information in a later update on the AI system, but I will leave you with a screenshot of the AI firing at other AI.

DHMC Dev Diary 5/2/2016

Hot off the presses of our last update, the team wanted to share some info and screenshots of the new mech appearance and customization.  We have been working to revamp the look of the mechs with a new material setup and some texture tweaks.  Bare metal and damaged paint should now look much more convincing, and the mechs as a whole have a more battle-worn feel to them.

Additionally, customization is now back in full swing, with the ability to change primary and secondary color (including alpha), as well as camo once more.  The way camo is handled has also been changed to better bring out the true color of the mechs.  Our next step will be to reimplement grunge using some new shader techniques, and tweaking the decals so they better blend in with the underlying armor of the mechs.  As promised here are a few shots of the new changes in the hanger:
