カスタム文字列によるフライング文字

説明:

次の例では、Script オペレータを使用して、シーンのテキスト オブジェクトに基づいて単一の文字を各パーティクルに割り当てます。ユーザは任意の文字を入力でき、フォントを定義し、Extrude や Bevel などのモディファイヤを使用してテキストの外観を変更します。また、パーティクル フロー によってテキストを示す文字のストリームを生成します。

用途:

このスクリプトは、Script_Operator 内部で使用されます。

効果:

注:

ソース オブジェクトは、何らかのメッシュ モディファイヤが上部にあるテキスト オブジェクトでなくてはなりません。このスクリプトはテキストの基本オブジェクト (baseobject)のフォントおよびテキスト プロパティにアクセスする必要があるので、スタックを EMesh に集約しないでください。

例:

    --The ChannelsUsed handler defines the channels
    --to be made available to the script.
    --For the list of all channels, see
    --Interface: MaxscriptParticleContainer

    --contains the Particle Container the script is applied to
    on ChannelsUsed pCont do(
    pCont.useShape = true --enable changes to the shape
    )

    --and create the text objects for every letter

    --Use different unique ID if reusing the code
    --multiple times in the same scene

    --scripts in the same scene
