toda vez que chego perto da caixa de bala da este erro.

NullReferenceException: Object reference not set to an instance of an object
UnityStandardAssets.Characters.FirstPerson.FirstPersonController.OnTriggerEnter (UnityEngine.Collider other) (at Assets/Scripts/FirstPersonController.cs:269)

Você postou o primeiro código (que está dando erro) de forma errada, escrevendo dentro da code box.

Poderia clicar 2x em cima do erro e informar qual linha exatamente está dando erro?

Por acaso seria esta?

Código:

Destroy (other.gameObject);

Tem algo linkado na variável "armaCurret" ???


Este objeto possui algum script que tenha a variavel "PentBala" ?

Sim o script eu mandei tambem.

Código:

armaCurret = GetComponentInChildren<MovArmasAkBehaviour>()as MovArmasAkBehaviour;

Isto acontece no awake, mas será que está pegando o componente?

Já tentou deixar a variável "armaCurrent" pública e ver se o componente é realmente setado depois que você da o Play ?

Já fiz isso.A menssagen que aparece e esta!

UnityStandardAssets.Characters.FirstPerson.First Pessoa Controller.OnTriggerEnter (UnityEngine.Collider outro) (pelo Assets / Scripts / First Person Controller.cs: 269)

Este objeto que tem a tag "Other" tem o script "Munição Behaviour" ???

E em relação ao que eu perguntei anteriormente, já deixou aquela variável pública para ver se o script está achando o componente?
