RecastT3D v1.1
by Kerry Enfinger · 05/22/2012 (1:31 pm) · 23 comments
RecastT3D v1.1
-- Updated to newest Recast/Detour codebase
-- Added Zones, Physical Zones, Triggers, and Items to geometry selections
-- Added water and river surface subdivision for better mesh control
-- Implemented bitmask to allow up to 32 types of meshes
-- Works on massive terrains
-- Added message boxes for notification of start/completion of navigation mesh
-- Optimized mesh functions
To see more capabilities of RecastT3D, please check out my previous blog:

I've also opened a forum at my website to discuss RecastT3D and the Torque Master Server software.

Utilizing Zones and Triggers in the geometry exclusion allows the developer to create areas in which the A.I. will not travel.
Great for creating safe zones and other areas in which the A.I. is not wanted to enter.
Using a Trigger mask, A.I. can be prevented from using this bridge.
A massive 20.5km x 20.5km terrain covered with a 5000 x 5000 navigation mesh.
The price for the package is $95.00 (Indie or Commercial) and can be purchased at:

You can also download a demo game from the above link to see the AI in action using the navigation mesh (make sure you have DirectX and Visual C++ 2010 runtimes installed).

Thanks for the comment. The master server will work for T3D, TGEA, or TGE.

Great to see this Kerry! What exactly is the licensing difference between Indie and Commercial?
#6
There is no difference between Indie and Commercial as of now. I kept the two different ordering options for statistical purposes.

I made the required source edits and recompiled. The World Editor will not load. Its just freezes and "Loading Editor"

Was this a previous game build? If it was, try deleting the old navigation mesh files in the levels folder. I have not seen that problem at all. What does your log files show??

Just did a build on a fresh install. No problems with the editor or generating a mesh. Please double-check the steps in the installation instructions and make sure that there is no conflicting scripts.

What is included in the package? C++ modifications, torquescript mods etc?

Included in the package is the C++ source (including the modified Recast/Detour library code), scripts and assets for the demo game, Visual Studio 2008/2010 project files for the library, and complete instructions on installation and usage.

Does this allow you to create nav meshes on selected terrain material types? e.g. on a road texture?
Cheers,

Will let you know

I will go through through the install again. I know I did find some errors on the PDF with regards to the code.Will let you know
#15
Could you please share the errors that you saw in the documentation? The integrity of the documentation is very important to me and I would like to ensure its accuracy.

Thats all that was happening on my end. All good now

@Kerry I think all the errors were were just from copy PDF to VS, not actually anything wrong with it. I can tell you how it is setup, it doesn't copy well, but no actual error with code.Thats all that was happening on my end. All good now

Regarding 3+5, does this mean that you could have a mob of AI actively avoiding eachother?
Regarding 8, What is the difference of these? Especially the sliced path that tickles my curiosity.
Obviously the smooth path is like a curve between the different nodes but does it create significantly more nodes or how does it work? Will it hurt performance?

Quote:5. Automatic position tracking of all moving game objects.
3. Automatic position tracking of all moving game objects.
8. Use straight, smooth, or sliced navigation paths.

Yes, the navigation module will track moving objects and replan around them on a time-scheduled basis.
A straight path calculates a path straight from point A to point B.
A smooth path uses the polygonal curves to calculate a smooth path between points.
A sliced path is a time-sliced path calculation allowing for less immediate overhead during calculation.
The smooth path may create more nodes than the straight path depending on the terrain but I have not seen any significant performance differences.

I have seen your master server.. Is that available for T3D or is it still just TGEA?
