概要

Unity の EventTrigger でダブルタップ・ロングタップ・フリックを扱えるクラス EventTriggerAdvance を作りました。
更に、それを拡張メソッドで簡潔に扱える拡張クラス EventTriggerExtension も作りました。
不具合や改善点等がありましたら、コメントをお願いします。

使い方

// ダブルクリック
eventTrigger.AddPointerDoubleClickListener((pointerEventData) => {/* 処理 */}, tolerance : 0.5f);
// tolerance : この値より入力が遅いと、無効になります（省略可能）

// ロングタップ
eventTrigger.AddPointerLongPressListener((pointerEventData) => {/* 処理 */}, tooFastToUp : 0.5f);
// tooFastToUp : この値より速く離すと、無効になります（省略可能）

// フリック
eventTrigger.AddPointerFlickListener((pointerEventData, flickAngle) => {/* 処理 */}, float tooShortSqrDistance : 500f, float tooLateToUp : 0.5f, float tooFastToUp : 0f)
// tooShortSqrDistance : この値よりフリック距離の平方根の方が短いと、無効になります（省略可能）
// tooLateToUp : この値より長く押すと、無効になります（省略可能）
// tooFastToUp : この値より速く離すと、無効になります（省略可能）

// ドラッグ移動・回転・拡縮
eventTrigger.AddDragToMoveListener(transform, (pointerEventData, pos) => transform.position = pos);
eventTrigger.AddDragToRotateListener(transform, (pointerEventData, rot) => transform.rotation = Quaternion.Euler(Vector3.forward * rot));
eventTrigger.AddDragToScaleListener(transform, (pointerEventData, scale) => transform.localScale = Vector3.one * scale);
// 1つ目の引数に Camera を追加すると Sprite 向けの処理になります（Camera を省略すると uGUI 向けの処理になります）

FlickAngle

FlickAngle にはフリックした角度の情報が入っており、AddPointerFlickListener の実行時に取得できます。

// -180f から 180f の範囲の角度を取得
float angle = flickAngle.angle;
// 0 : 右
// 90 : 上
// -135 : 左下

if (flickAngle.IsRight) Debug.Log("右方向にフリックされた");

// 上記のプロパティの許容角度は±45度です
// 最後に Side が付いているプロパティは、許容角度が±90度になっています
if (flickAngle.IsRightSide) Debug.Log("右側にフリックされた");

// 斜め方向のプロパティ
if (flickAngle.IsTopLeft) Debug.Log("左上方向にフリックされた");

// 角度を指定して判定
if (flickAngle.CompareAngle(angle : 135f, range : 22.5f)) Debug.Log("北北西方向にフリックされた");

// 角度の差を取得
float diff = flickAngle.DiffAngle(angle);
// 角度の差が時計回りなら負の値、反時計回りなら正の値
float signedDiff = flickAngle.SignedDiffAngle(angle);
