Wie Swipe auf Unity3d erkennen kann nur schauen Bild

Question

Ich fand, wie die Berührung auf der Ober- oder Unterseite, um zu bestimmen, aber ich weitere Informationen benötigt. Ich habe auf dem Bild gezeigt, was ich brauche. Sag mir, wonach ich suchen soll.

Gib mir einen Hinweis bitte

Hallo dieses Skript nicht getestet, es hilft schrieb.

Edit: ich nicht gesucht habe, bevor diese Antwort veröffentlichen, aber ich denke this answer Besser ist
