Been working and reworking a whole lot of things in SlingBot Boarding over the past few days. I've finished up some of the lingering aspects of the NPC steering code, so they're a bit more reliable and less twitchy. 
I've also been reworking some of the player controller code... Mainly because I brought back the LOOP!! 
I know I never put it in the game anyhow, but I posed a teaser of it a while back. And well, it's still not IN the game, it'll be another day or two before I put out a new build, lots to do.
So, great, a big loop to nowhere eh? Nice one dude...
haha, not really..
Here you see the invisible arena that appears as you complete the SuperLoop!
Inside this arena we have a new prototype Snowball Turret!
I know, SUPER INTIMIDATING right? haha!! I'll model something more.. More! Later.. For now, it appears to shoot snowballs just as well as a fancy model will.
As the basis of my first level prototype(and it will likely be the contents of Level1) I have a grid of 20 of these guys in the middle of the arena that you must disable by exploding a snowball near them. When they are hit with an explosion that is strong enough they get knocked off their pads and can no longer fire.
I have not yet, but I will be enabling a damage and/or power meter for arena levels and racing so that I can establish a few more lose scenarios and increase the difficulty in more ways.
Another thing I've discovered on my journey to getting Tube riding working, was how to enable extended flight in a controllable manner. So, you should expect some form of that to be appearing before too long. But not before we have some progressively harder levels to defeat!!
So, what happens when you defeat an Arena Level? Well, that's easy, your defeated foes start appearing in the wild. They will show up in random places around the park and will also be setup along user generated courses. This will allow the entire game difficulty to increase as you progress through the levels. For example, after defeating level 1 and it's array of snowball turrets, you can expect to find snowball turrets showing up on race courses and in random spots in the park. With bonuses and rewards and awards for defeating them wherever they appear!!
Well, that's about all I feel like divulging at the moment! More.. tomorrow probably.
Happy Coding Everybody!
I like the loops and turret idea!
