Unity3D腳本怎么實(shí)現(xiàn)撞擊

RaycastHit rayHit;

void Update()
{
Vector3 fwd = transform_TransformDirection(Vector3.forward);
if (Physics.Raycast(transform_position, fwd, 10))
print("There is something in front of the object!");

if (Physics.Raycast(transform_position, fwd, out rayHit, 1))
{
print(rayHit.collider.gameObject.name + " " + rayHit.distance);
}
else
{
print("nothing");//這一輸出只在開(kāi)始運(yùn)行出現(xiàn)，當(dāng)上面輸出一次后，即使前方?jīng)]有物體，也不再輸出了.
}
}

將你的代碼放到update里面
經(jīng)過(guò)測(cè)試沒(méi)有問(wèn)題：）
