Elasticidade e fricção em 2D.

0:00:05.445,0:00:07.445
Existem 4 items que trabalham em conjunto

0:00:07.445,0:00:10.001
para fazer uma bola quicar em 2D.

0:00:11.478,0:00:13.478
Um sprite image para a bola

0:00:14.075,0:00:16.296
Um componente colisor para dar à imagem

0:00:16.296,0:00:18.296
uma presença física na cena.

0:00:19.155,0:00:21.957
Um material físico 2D atribuído ao colisor

0:00:21.957,0:00:23.957
para definir a fricção e elasticidade.

0:00:24.954,0:00:28.158
E um componente rigidbody 2D,[br]para permitir que a bola

0:00:28.158,0:00:31.537
seja afetada por forcas da física, [br]incluindo gravidade,

0:00:31.537,0:00:33.509
e para compartilhar eventos físicos,

0:00:33.509,0:00:35.509
como colisões e gatilhos.
