画面をクリックして、キャラクターをその先に移動させたいです。即座にではなく、指定された座標まで「歩きます」。現在、私は JLabels を使用しており、静止画像のみを使用する場合は問題ありませんが、画面のどこかをクリックするたびに、その正確なポイントに画像が表示されます。誰かが私にいくつかのヒントを教えてもらえますか?

編集:ペイントクラスをオーバーライドして、そのようにいくつかのアイテムを描画する必要がありますか?

ここにいくつかのコードがあります：

Not instantly, but rather "walk" to the given coordinate.

Then you need to use a Swing Timer. The Timer is used to schedule the animation. So you would need to calculate a path between the two points. Every time the Timer fires you would move the label a few pixels until it reaches it's destination.

There is no need to do custom painting for this. A JLabel will work fine. The hard part is calculating the path you want the character to take. Also make sure you use a null layout on the panel you add the JLabel to, which means you will also need to set the size of the label equal to the preferred size of the label.
