Retrieves all contact points for this collision.

When retrieving contacts, you should ensure that the provided array is large enough to contain all the contacts you are interested in.

This function also means that no allocations occur, which means no work is produced for the garbage collector.

You can check how many contacts are available using contactCount.

public int GetContacts (List<ContactPoint> contacts);

파라미터

contacts A list of ContactPoint used to receive the results.

반환

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

설명

Retrieves all contact points for this collision.

When retrieving contacts, try to make the provided list large enough to contain all the contacts you need. If the list is not large enough, Unity will automatically increase its size so that it can contain all the contacts. The list is usually reused, so it should be large enough to return a reasonable quantity of contacts. If the list does not have to be increased in size then this function will not allocate any memory, which means no work is produced for the garbage collector.

You can check how many contacts are available using contactCount.
