OOP I did it again ...

I started out yesterday morning looking to improve my understanding of types and methods in Blitzmax, and figure out how to use object-oriented programming (OOP) with it. I have only been programming in Blitzmax since the beginning of December last year, and only programming with C++ since the middle of October last year and The Leadwerks Engine since the beginning of October last year. So I am still on a very high learning curve in this regard.

As usual, for me, I started out on one thing and ended up on another. I found a link on the old forum for a small tutorial on Object-Oriented Programming in BlitzMax By John Judnich. But by the time I had got to page 6 of 21, I was already off on a tangent and found myself working on a simple NPC type containing a creation method and simple seek behaviour method, after all I was now an expert after only 6 pages lol.

I had already been "playing" around with some simple AI which showed vague promise, for an Idea for a small project.

An hour and a few more "tangents" later I had managed to restructure the basic code for NPC creation and basic seek behaviour into an NPC Type using methods. This now allowed the easy creation of an NPC, in this case a rather nifty bug, created by ‘Psionic’, with its walking animation handled by its Lua script on load.

The test scenes buildings are by GIMPY73 and the Freebeast model is by ‘Psionic’.

Test of Basic NPC creation : Seek : Pursue : Attack Behaviour using OOP in Blitzmax running the Leadwerks Engine. Extra flags added for behaviour to the NPC Type with extra methods to communicate with the NPC model's Lua scripts for animation control. Although I did manage to hardcode a typo in the "Pursuit" flag.

Of course this basic AI is nothing like the calibre of AI work being done by Chris Paulson or Pixel Perfect, but I had to start somewhere and this seemed the best place, so far I am pleased with my meagre results.

I recall Josh showing interest in integrating Recast into the editor, this would truly be a useful addition. Leadwerks could really use an integrated AI starting point. Thats not a complaint just an observation. Recast integrated into the engine and editor could be that starting point.

SSAO, SSDO or NO in Leadwwerks.

I have not entirely made my mind up on the new SSDO (screen-space directional occlusion). I liked, in some circumstances, the effect SSAO gave, especially on bump mapped brick textures. But I find SSDO to be quite "fizzy" possibly from the curve on the camera look values. This may well be down to settings but so far try as I might I still get this. Not sure it will be useful in an FPS situation as the HUD model seems to interact.

It does however have a very pleasing effect on "organic" assets.

I think I will "play" some more with it, see if I can reduce the "fizzing".

A superb addition

The new Indoor Lighting Optimization is truly a fine addition to the Engine. It has taken a little while to get into the habit of automatically setting the lights to Dynamic, Dynamic + Static, Static or Dynamic + Static + Buffered, as well as the needed setting for the objects in the scene. Objects that would normally always be static I have, for the time being, simply added an ini file to set them to static automatically. This will later be set via their scripts but for now it suffices.
