Modular City Kit – Unity Engine

In the vein of giving back to the community, here is another cool freebie. These are low poly modular street sections and buildings that can be used to populate your own city in Unity. The video demonstrates how to use the pieces and contains the download link for the Unity project source. Enjoy!

Go Kart Demo NGUI Update

1-18-13_WebDemo

Web playable update: http://dl.dropbox.com/u/16956434/Kart_Race_Demo/1-18-13_Webplayer/WebPlayer.html

Converted all in-game HUD elements to NGUI. Now they’re rocking 2 draw calls of the entire UI (1 is for the font and other for UI elements.) I am aware of the position indicator doing it’s bugginess. What is occurring, is that when the player and AI are equal in Laps Completed, Waypoints Passed and are relying on Distance to Next Waypoint to calculate who’s in front..well that value is jumping back to 0 at each way point being passed (resets value). So I think because the data is relying on the rapidly changing value to determine race position in these circumstances, it’s glitching a bit. Once you determine a lead by passing more waypoints in general or more laps, the position indicator is fine. It’s a bug and I’ll fix it.

I’ve also added in driver camera functionality if you click the camera icon in the top of the game window. Helps with the sense of speed a bit, but I’ll do more with the far camera’s sense of speed when I get to that. For now I’m working on getting the second functional AI vehicle in…I intend to have a race between (3) Karts.

Setting up simple vehicle AI in Unity

Latest tutorial upload for all of you Unity folks. This is a video that will help you get simple AI going in your racing or traffic games. The video includes a 1.4MB download of the entire Unity project seen in this tutorial (look in the video description).

Checkpoint and Lap System for Unity

This is a small project that teaches you how to implement a simple checkpoint system and lap system. The checkpoint system is used to prevent cheating (i.e. backing up and driving over the finish line to increase lap count.) The player vehicle must pass through a series of checkpoints (which you determine), before the lap counter will increment.

Unity Engine – Stock Car Demo Project

Hey everyone. I’ve put up a lot of free Unity goodies. Today is a full free project of a Nascar driving demo. It’s pretty decent physics for a Nascar Stock car. The track is based off of Daytona International Speedway. Anyways, go check out the freebies at http://www.fatboxsoftware.com under the Resources tab.

Updated Build – Super Kart Racing Demo

Build has been updated today with actual updating GUI elements for lap counting and lap timing. It’s rough right now, and not the final look of the text in the UI, but the functionality is working (only slightly buggy :). I’ve also implemented some nice UI graphics that slide in quick when you hit a checkpoint in the road. They ease in/fade in and ease/fade out when triggered onto the screen.

Unity Kart Demo – Menu UI

Worked on the HTML for the web page interface for the game. Also I’ve worked more on the main menu interface, trying to get it closer to representing something useful. Today was mostly HTML and main menu work for the buttons, etc. I’ve also got a splash page working (with the fatbox logo) as the game menu loads.

As usual here’s the link, go check it out! https://dl.dropbox.com/u/16956434/Kart_Race_Demo/WebPlayer.html

Unity Kart Demo – Lap Count System (including checkpoints)

[youtube http://www.youtube.com/watch?v=cC22FWRe11w&feature=youtu.be%5D

Decided to start doing a daily video log (2-3 minute videos max) describing what I accomplished in the build that given day. Also a good spot to share info, scripts and any implementation specifics with other folks.

Unity Kart Demo – Web Playable

So I’ve have some updates:
As of today I finally gotten a small LCD tach and speedo on the steering wheel working. As of right now it’s not reading out RPMs. The MPHs are not rounding off properly (bad math code or something) so they jitter a bit on the panel. The track is standing in for the final path, it’s textures and UVs are not complete either so you’ll see some parts of the track where the grass/dirt blend is not broken up. Also all of the GUI elements on screen are not the final game UI. They are stand-in debugging items.

Integrated new speed-based vehicle handling (not sure how accurate it is yet)..but basically your steering becomes less sensitive the faster you go. I’ve also got a new sound manager working. You have engine sounds based on RPMs, you have a wind passing by you sound based on velocity. The sounds are not fully looped yet in Audacity, so you will hear some pops. I’ve also implemented a camera shake animation on the cameras based on velocity as well. The camera shake has been polished up in the latest build which isn’t up tonight.

I’ve gotten feedback about implementing a handbrake for sliding through turns and feedback about adjusting the slip when taking turns and such. I’m working on, the physics calculation stuff is a little more complex so I usually tackle easier things first.

Next task is to get some raycast AI working in the scene (one’s that can avoid obstacles dynamically, etc.). So not just the simple “follow a spline” fellows.

Anyways here’s a link:  http://www.jamesarndt3d.com

This is where I will host the game (so I will test it this way as well)….hit the button at the bottom called “Kart Race Experiment”. It will take you directly to the current build.
