aStar Tutorial does not work for me

by Justin Jones · in Torque Game Builder · 07/17/2009 (7:54 pm) · 5 replies

I am trying out the aStar tutorial found in the TGB Online Documentation here

http://tdn.garagegames.com/wiki/TGB/Tutorials/Basic_aStar

First off the tutorial says to set-up different things by looking at images, which are not there on the tutorial page in the first place.

Anyway I followed the tutorial exactly and on running it I get no script compile errors. My "player" can move about as per the behaviour.

However the other aStar object does not move at all.

On checking the console I see this:

Loading compiled script D:/TGB174/MyProjects/aStarFollow/game/data/levels/astar.t2d.
game/gameScripts/actor.cs (16): Unknown command findDestinationPath.

and more of the same. Can somebody here please explain what is going on here?

I am frustrated as this is the 3rd "Tutorial" that does not work in the "official Online Documentation" for TGB.

Thanks

TDN A* Tutorial is not an official documentation guide. It was written by a community member.

The official online documentation has an A* reference, but not a full blown tutorial. The offline documentation, which has a similar A* tutorial, is very outdated and not recommended over the Official Online Documentation

Thanks Mike. I realised after posting that this was not "official" documentation.

I followed the link you provided but the only reference to aStar is this in the Reference section:
http://docs.garagegames.com/tgb/official/content/documentation/Reference/A-Star%20Path%20Finding.html

and at the end it has this:

<i>Use of the TGB A-Star Implementation

An introduction tutorial is provided <here> to guide you through the features of the TGB A-Star system, and the AStarDemo game example demonstrates the completed tutorial�s capabilities</i>

What does <here> mean?

This barely scrapes the surface and does not show how to use it.

@Justin - Agreed. The A* that ships is a great starting point, but does not going deep enough into the details. I plan on dedicating a very large guide to the core systems of Torque 2D, such as A*, while writing the new documentation.

That "here" is supposed to be a link that opens a the A* sample project in the TGB SDK.

Thanks Mike

I will take my interests to other topics while waiting for the new documentation.

Unfortunately so far I have hit two dead ends - aStar and Networking(checkers tut not working)

On to the GUI I guess.

What is the current status of A* documentation of how to implement it?
