Bend-y and Weasel-y Dragons (31. Jul 2017) [ Comment ]

Forum Administrator
Sean demonstrates how bend-y and weasel-y dragons really are. If you can't get some place don't forget about your partner.

The current setup for Sean used an Elongated Box setup. This setup worked but had been tricky to use for players to get around tight spaces.

I've experimented with a couple of different setups and script versions until I got the behaviour working the way I had in mind. Sean is now using a Complex AI Collider setup which allows her to Weasel around corners easily ... (for more see news post below)

Meet the Player-Base (25. Jul 2017) [ Comment ]

Forum Administrator
Now a little something in between.

Introducing Work-In-Progress on the first Player-Base. That's a game developer term for a place the player is going back to regularly. Typically this contains stuff like save spots, shops or whatever. Here the Player-Base provides the player with a laptop to review his case findings or doing some cybernet researching. It's also the place to wrap over to a new day (fast-forward sort of thing). There are also additional things linked to these places but I leave this open for discovery. There are though multiple such Player-Bases players can use.

A very long time passed since the last news. One reason had been me moving to a new place which took longer than expect. Then there had been lots of work too correlated to show by its own. And finaly but not least there had been some nasty incidents at ModDB where somebody with site moderator power (as it seems) vandalizing the profile of my project which I restored. Due to this incidents though I put a news ban on ModDB which had been in effect since somewhere the beginning of this year. In the mean time though a couple of people asked me to lift the ban. When I found a way to protect my work by reworking the Wiki to host the articles I decided to lift the ban as on my wiki my work is safe. I don't want to warm up this story more than I just did. Important now is only that ban is lifted. For me this incident is now a matter of the past and shall stay there. Let's move on to what is really important.

Drag[en]gine Wiki Overhaul
The Drag[en]gine Wiki has been completely overhauled. To help prepare for a future release of the game engine this wiki is turned into the SDK and first source of information. Hence it is made for the developers wishing to work with the game engine. Especially in light of the incidents that happened the wiki has been modified to hold also all the articles from now on. I'll now only make short bullet lists of what has happened linking to the wiki pages. No articles will be posted anymore on ModDB (on my wiki they can't be vandelized). The articles contain in depth details. It's really worth reading them if you want to know all over the Drag[en]gine.

The Big What Has Happened In All The Month List!
Here the list of what happened during all these month. Click on the links for detailed articles about the topic:
  • Better organized texture property listing
  • New modules listing with individual pages per module: See OpenGL
  • Physically Based Rendering for better materials, lighting condition independent material creation and a lot easier for artists to create materials with. In short a superior system for artists and game developers to work with.
  • New texture properties for PBR: reflectivity, roughness with artists aid chart, roughness.remap.lower, roughness.remap.upper, environmentmap.
  • Normal map strength support: alter normal map influence if required dynamically
  • Tintable materials: dynamic, run-time tinting of materials for higher diversity. Overwrite for individual textures inside the world editor. It's a pure game script approach so you can change and extend all this to your hearts desire in your game scripts.
  • Dynamic environment maps
  • Occlusion Mesh System with implementation details about the new occlusion testing system
  • Trigger expression editor in the world editor with live trigger table to test your trigger expressions
  • Tree Branch Unwrap script for ngplant generated trees imported in Blender3D
  • Various trees for the streets with ngplant
  • First Mission Map "Old Industrial Area" (in Video). Various models for it: railings, bollards, tree grates, traffic signs (configurable text and symbol rendered at run-time; no texture required), traffic lights (dynamic lights using dynamic skins; switching states using triggers), poles and carriers for traffic signs and lights, company name panels, garbage bins, chairs and so forth, pipes and decals
  • Various materials based on PBR
  • Generic facades. Modular system. Facades for base and upper floors. Windows with dynamic day/night lit/unlit cycles using a random scheduler (in Video). Large variation using tintable materials
  • LOD System with intelligent error metric
  • Tree Canopy LOD
  • Ladder interaction. Realistic ladder usage with full body motion feedback and fluid controls (in Video)
  • Lighting improvement in shadow areas
  • AO Fresnel reduction for PBR
  • Various Blender3D scripts for exporting and tools including normal conversion tool (GBuffer NormGen) all written for Blender 2.65 taking advantage of new features
  • Decals have now texture transform support (texture animation support)
  • New texture properties: texcoord.clamp and texcoord.scale[/list]

    And here a video showing the Old Industrial Zone map. Cut together various video clips to give a little overview of the map, the game controls, the movie camera and other stuff. Please excuse the frame rate but GLC gets into problems once the GPU memory is crammed full. I'm working on improving that. Also the video codec killed the night scenes so I cut out most of it as it is too dark to see. See the Map Screenshots for more images including night scene how it really looks like.

    Two example screenshots I uploaded also here. The rest you find in the Map Screenshots Gallery.

    It's time now for an overdue all important addition to the shader system to allow for even more power and versatility that I need to get that performance punch to crank up frame rates. My Radeon 4870 HD is not the youngest and most powerful graphic card anymore but I have the will to get the most punch out of it with my engine. Besides this I want to get the first mission into a playable state with first investigation work going on. A lot of the required engine work is done already. And that is the most time consuming part so far. Furthermore more articles will be moved one by one to the safety of the Wiki.

Interaction News Post (12. Jun 2011) [ Comment ]

Forum Administrator
Quite some time since the last news post. This has been mainly due to story writing work. More than 3 weeks went down the drain to building up a document to hold the important corner stones of the story. If this would be a boring FPS or an MP game then story would be a no-brainer. Since this is though a game where investigation is part of the job the requirements on the story in terms of logic and coherence are quite high. This is especially time consuming if you write such a story for the first time. Another problem is to allow the player a certain degree of freedom in how he pulls off his investigation. All this together ate up a lot of time leaving less for working on the game. Nevertheless I'd like to take the opportunity to talk about the new stuff concerning the actual game itself.

Most of the work went into improving the conversation system. For this Target and Look-At have been added. Targets simplify the process of defining targets for cameras or other kinds of actions in a conversation. In addition to the existing parameters for actor speaking 3 new Look-Ats have been added: Body, Head and Eyes. Targets can be anything from actors in the conversation to world objects nearby. The system is thus quite variable. The major improvement though is adding the conversation system to the game (as it worked so far only in the editor). Besides that new interactions have been added. But it's easier to see it in action. Read the text below the video to learn what each sequence shows.
Video ModDB

First part shows the memo pad handling to work with the new player character (especially it's now right-handed as it should be). Shown is picking one pad up. I know it's strange as he grabs it with the right hand but holds it with the left but I had only the right hand animation already from the previous model. Will be changed later on. Pads are now used using animations (your finger there). Also dropping shown. Next is picking up a story memo pad. You have to pick this up to get a conversation going later on.

Next shown is the entire conversation system. Added support for conversation introduction thus saying hello and stuff like that to make it more natural. Then selecting the appropriate topic to talk about. That topic only exists if the memo pad has been picked up beforehand. Then comes lots of new stuff. Added more camera shots for variety. Added face and eye look-at targets. Also included eye-blinking now. More things I added is one actor giving stuff to the other. This is a matched animation so if you look at it from the outside they properly hand over an item no matter the distance between them (IK stuff). This works using player actions which means it can be used for anything including the player and NPCs. Added a command interface for that. A rather simple system sending a text command to the an actor.

Every actor in the game has a PlayerActions object assigned. This one defines how the actor behaves right now. The action can be changed by assigning a new PlayerActions object (typically a sub-class). The trick is now that for everything these actions are used. The only thing that changes between a player actor, an NPC actor as well as conversation is how commands are given. For player actors commands come from keyboard/mouse. For NPCs the commands come from an AI object. And during conversation commands are send to these actor actions. So I have to implement an interaction only once, as a PlayerActions sub-class and can then use it for everything just by giving the right input. Here a bunch of actions are involved, HAGrabProp, HAGiveProp and HATakeProp. A simple system to use but powerful.

There's also support for player choices not shown in the video. Simply shows a list of options on screen the player can select one from. Each option has a list of conversation actions assigned so you can alter the course of conversation if required.

Last but not least the same as with starting the conversation. Shows some goodbye stuff when the player leaves. Same idea as with saying their hellos. All of these are conversation topics so you create them the same way as any other conversation.

Out of conversation the next thing shown is some interactions. The first one is taking a seat, here on an infirmary bed. Introduced here the actor align action. That's a glue action which aligns an actor before running the next action. Used to position the actor in the right place for the next action to work properly. Showing this in the second time he sits down where the player is standing far away. So sitting down is 3 chained actions (HAAlignActor, HASitDown, HASitting).Simply but versatile. This sitting down might not look useful yet but it will be used for NPCs (talk to them while they sit behind there desk) and using computers (player sits down on the chair in front of it).

Last thing shown is an idea I had to make investigation a bit more interesting. Here an action to look under the bed. The idea is to be able to look for clues in less ordinary locations. For this one I filmed myself and used this as reference making the animation.

Besides this a bunch of under-the-hood stuff has been added to. This includes a bunch of conversation actions and conditions including working with local variables (integer, valid during a conversation session) and working with actor parameters (integers). Actor parameters are interesting as they store information like the mood of the actor and other information. Asking irrelevant stuff or otherwise annoying an NPC with questions drops their “like you” parameter. If this one is too low they won't talk with you anymore. So think first what you ask. Careless pressing makes your life just harder. The mood system is though still work in progress so I'll talk about that later on.

I wanted to get this conversation system out of the way as quickly as possible so I can do more engine work. There are a few things on my list to do including AI, Path-Finding and Global-AO. Stay tuned.
