=ナビゲーションメッシュとは何か？=

散らかったら部屋を作った場合、アクターをナビゲートするために必要になるものです。[[:Category:Navmesh|navmesh]] を見てください。単純に言うならば、ナビゲーションメッシュはアクターが歩く場所を伝えるためのポリゴンのコレクションです。

私達がゲームをするとき与えられた情報を得るのは簡単なことです。私たちの頭脳は全てのヴィジュアルの詳細、常に描画された結果と予想を処理できます。残念ながら、AI システムは人間の頭脳の足元にも及びません、従って、私達が与えた情報に依存します。ナビゲーションマップは、AI アクターが与えられた空間を認識するための重要な知識のことです。

ナビゲーションマップエディターは骨の折れるツールです - 最初はイライラさせられるでしょう。着実にステップ・バイ・ステップで学んでいきましょう。一度原理を学習すれば、すぐにナビゲーションマップのエキスパートになれます。

{{NewFeature|GECK users take note: not much in the way of navmeshing ''by hand'' has changed. There have, however, been additions to auto generation, such as the all-new "''Recast''" generation mode, which is covered in this tutorial.  For more information, check the [[Navmesh Generation]] page.

=ナビゲーションマップの自動生成=

ナビゲーションマップのすべての作業は、完全に独立したエディタモードで行います。このモードに移行するには、メインツールバーのナビゲーションボタン (''Fig. 4.1'') を押すか、'''"CTRL+E"''' を押してください。[[Navmesh_Toolbar|Navmesh toolbar]] (''Fig. 4.2'') が現れます。

We don't actually need to use anything on the Navmesh Tool Bar in order to auto generate our navmesh; it exists as a convenience. We do need to be in Navmesh Mode in order to use auto generation, however, and the presence of the toolbar lets us know that this is the case.

There are four types of auto-generation: [[Navmesh_Generation#Object-Based_Generation|Object Based]], [[Navmesh_Generation#Havok-Based_Generation|Havok Based]], [[Navmesh_Generation#Recast-Based_Generation|Recast Based]], and [[Navmesh_Generation#Advanced_Generation|Advanced]].  For the majority of interiors, you'll want to use the Recast Based generation and clean up your navmesh by hand afterwards. This tutorial will not go into depth on [[Navmesh_Generation#Object-Based_Generation|Object Based]] or [[Navmesh_Generation#Havok-Based_Generation|Havok Based]] generation. Advanced users may opt to create all of their navmeshes by hand. Some find this faster than auto generating and then cleaning up by hand - it's all a matter of preference once you become comfortable with the system.

{{NewFeature|GECK users take note: [[Navmesh_Generation#Object-Based_Generation|Object Based]] and [[Navmesh_Generation#Recast-Based_Generation|Recast Based]] are new generation modes created for the Creation Engine.}}

Let's use [[Navmesh_Generation#Recast-Based_Generation|Recast]] generation to create an intial pass at navmesh in LokirsTomb:

# Click on the [[Render Window]] to make sure it's the active window.

# Make sure you have nothing selected in the render window (if you're not sure, just Left-Click somewhere in the [[Void]] or press the '''D''' key).

# Choose Recast Based Generation from the Navmesh menu in the main toolbar: '''Navmesh > Generation > Recast Based Generation'''.

# The '''Recast Navmesh Generation''' dialog will appear. (''Fig 4.3'')

# Don't worry about what all of the different values mean. Just make sure your values are similar to those pictured in ''Fig 4.3'' and hit '''"OK"'''.

# Click '''"OK"'''. It may take some time to generate, depending on your PC.

# Once it's done, the navmesh should look similar to that shown in ''Fig 4.4'' and ''4.5''.
