public int GetContacts (ContactPoint2D[] contacts);

パラメーター

contactsAn array of ContactPoint2D used to receive the results.

戻り値

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

説明

Retrieves all contact points for this Collider.

Contacts involving a Collider2D set to be a trigger will never be returned here because trigger Colliders do not have contact points.

You should pass an array that is large enough to contain all the contacts you want returned. This array would typically be reused so it should be of a size that can return a reasonable quantity of contacts. No allocations occur in this function which means no work is produced for the garbage collector.

public int GetContacts (Collider2D[] colliders);

パラメーター

collidersAn array of Collider2D used to receive the results.

戻り値

int Returns the number of contacts placed in the colliders array.

説明

Retrieves all colliders in contact with this Collider.

You should pass an array that is large enough to contain all the contacts you want returned. This array would typically be reused so it should be of a size that can return a reasonable quantity of contacts. No allocations occur in this function which means no work is produced for the garbage collector.

public int GetContacts (ContactFilter2D contactFilter, ContactPoint2D[] contacts);

パラメーター

contactFilterThe contact filter used to filter the results differently, such as by layer mask, Z depth, or normal angle.
contactsAn array of ContactPoint2D used to receive the results.

戻り値

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

説明

Retrieves all contact points for this Collider, with the results filtered by the contactFilter.

Contacts involving a Collider2D set to be a trigger will never be returned here because trigger Colliders do not have contact points. This is true even if the contactFilter has its ContactFilter2D.useTriggers set to true.

You should pass an array that is large enough to contain all the contacts you want returned. This array would typically be reused so it should be of a size that can return a reasonable quantity of contacts. No allocations occur in this function which means no work is produced for the garbage collector.

パラメーター

contactsA list of ContactPoint2D used to receive the results.

戻り値

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

説明

Retrieves all contact points for this Collider.

Contacts involving a Collider2D set to be a trigger will never be returned here because trigger Colliders do not have contact points.

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.
