とりあえずやってみる
これまでに使ってきたサンプルをベースに、
- PROTO側 : 形状側を2部品(ローカル原点を除いて)に分け、部分着色をできるようにする
- EXTERNPROTO側 : 時間軸に沿って移動やら回転やら
をやってみた。
PROTO側

できたはいいけど、EXTERNPROTO側に回転の指示を与えているためすこぶる長くなってしまう。
これを全身部品数分、とかもう苦行にしか思えないよね…
ということで、回転の指示もPROTO側に与える、という方針で作り直してみた。

やった！これで1部品の世界ではおおよそできたと思われる。
やったこと
- 部品の定義（形状、動作回り）を別ファイルにわける
- 時間軸に沿って移動・回転させる
- 部品の一部を時間軸に沿って変色させる
