VisibleSimで遊んでみた--アプリの作成--

Last updated at Posted at 2022-07-26

注意
　この文章の筆者は専門家ではないので鵜呑みにしないこと。
　正しい情報は参考リンクから調べてね。　

はじめに

　VisibleSimをいろいろいじって動きを調べていく。
まずは自分で新しくアプリケーションを作成するところをやっていく。
サンプルアプリにhexanodes_demoがあるのでこれを複製していく。

遊んでみた

ディレクトリ構成

　まずはディレクトリ構成を確認。
今回は新しくシュミレーションを行っていくので、applicationSrcとapplicationBinがメインとなる。

.
+-- applicationsBin/
|   +-- [BlockCode Applications]
|	+-- meld/
+-- applicationsSrc/
|	+-- Makefile
|	+-- [BlockCode Sources]
+-- doc/
|	+-- Doxyfile
|	+-- html/
|	+-- Makefile
|	+-- [Various Documentations]

|	+-- [UI Help Files]
+-- utilities/
|	+-- meld-compiler/
|	+-- LMParser/
|	+-- configGenerator/ (nazandre/VisibleSimConfigGenerator)
|	+-- blockCodeTest.sh

ソースコードの作成

　早速コードを書いていく。アプリ名はhexTestとする。
手動で追加、更新するファイルは以下の6種類。

  • applicationsSrc/hexTest/hexTest.cpp
  • applicationsSrc/hexTest/hexTestBlockCode.cpp
  • applicationsSrc/hexTest/hexTestBlockCode.hpp
  • applicationsSrc/hexTest/Makefile
  • applicationsSrc/Makefile
  • applicationsBin/hexTest/config.xml

それでは上から追加していく。

ビルド

　公式ドキュメントによるとsimulatorCoreディレクトリをビルドした後変更がなければ直接ApplicationSrcから直接makeをしても問題なさそうだったので、やってみたがエラーになった。ApplicationSrc/hexTestも同様。

Alternatively, the user can call make directly from the block code directory, if no change has been made to core, since the static libraries are used for linking.

というわけで普通にリポジトリのルートからmakeを行う

VisibleSim/
make

実行

ビルドできたので動作確認してみる。

applicationsBin/hexTest
./hexTest

rを押すとくるくる回り始める。かわいい

おわりに

無事にサンプルのクローンを作成できたので、次は設定をいじってみる。
