私のウェブサイトにアニメーション名like thisを追加しようとしています このアニメーション名のサイズは大きすぎます。どのようにバグもなく、そのサイズを変更する方法。こここのアニメーション名(キャンバス)のサイズを変更するには

コードである:

各文字を構成する気泡はalphabet.jsスクリプト内のデータの配列によって決定されます。これは、サイズのような通常のフォントの仕組みが適用されないことを意味します。

文字のサイズを変更するには、六角形から泡の配列に変換した後に泡の座標を拡大縮小します。

ここでは、スケーリングを適用する簡単な方法があります。 bubbles.jsスクリプトの内容が変更されました。

function Point(x, y, z, size, color) {  
var globalSizer = 0.3; 
x = Math.round(x * globalSizer); 
y = Math.round(y * globalSizer); 
z = Math.round(z * globalSizer); 
size = Math.round(size * globalSizer); 

globalSizerの値を小さくすると文字が小さくなります。

var orange = [40, 100, 60];

素晴らしいが、私はそのロングコードから何かを理解していないです:ここでは全部の作業です。サイズを編集できる場所を教えてください。ありがとう –

+0

私は、私の答えでコードの最初のブロックを見ました。 bubble.jsファイルには、文字のサイズを変更できるAPIは公開されていません。代わりに、長いbubbles.jsファイルをダウンロードし、 "function Point(x、y、z、size、color){"という行を見つけて、次のようなコードを挿入します:var globalSizer = 0.3; x = Math.round(x * globalSizer); y = Math.round(y * globalSizer); z = Math.round(z * globalSizer); size = Math.round(size * globalSizer);変更したbubbles.jsファイルをサーバーに保存し、Webページにそのファイルを指定します。 –
