public int Cast (Vector2 direction, RaycastHit2D[] results, float distance= Mathf.Infinity);

パラメーター

directionCollider2D 形状をキャストする方向を示すベクトル
results結果を受け取る配列
distanceMaximum distance over which to cast the Collider(s).

戻り値

int Returns the number of results placed in the results array.

説明

All the Collider2D shapes attached to the Rigidbody2D are cast into the Scene starting at each Collider position ignoring the Colliders attached to the same Rigidbody2D.

This function will take all the Collider2D shapes attached to the Rigidbody2D and cast them into the Scene starting at the Collider position in the specified direction for an optional distance and return the results in the provided results array.

The integer return value is the number of results written into the results array. The results array will not be resized if it doesn't contain enough elements to report all the results. The significance of this is that no memory is allocated for the results and so garbage collection performance is improved when casts are performed frequently.

さらに、この関数はコライダーの開始位置で重複する他のコライダーを検知します。この場合は、キャストする形状はコライダーの内部で開始し、コライダーの表面を横切らない場合もあります。つまり、返された衝突の法線が、テストする direction ベクトルのリバースに設定される場合は、衝突の法線が計算されません。

The contactFilter parameter can filter the returned results by the options in ContactFilter2D.

さらに、この関数はコライダーの開始位置で重複する他のコライダーを検知します。この場合は、キャストする形状はコライダーの内部で開始し、コライダーの表面を横切らない場合もあります。つまり、返された衝突の法線が、テストする direction ベクトルのリバースに設定される場合は、衝突の法線が計算されません。

戻り値

void Returns the number of results placed in the results list.

This function will take all the Collider2D shapes attached to the Rigidbody2D and cast them into the Scene starting at the Collider position in the specified direction for an optional distance and return the results in the provided results list.

The integer return value is the number of results written into the results list. The results list will be resized if it doesn't contain enough elements to report all the results. This prevents memory from being allocated for results when the results list does not need to be resized, and improves garbage collection performance when the query is performed frequently.
