我正在尝试将Unity生存射手游戏部署到android设备。除了当我射击敌人时，游戏工作得很好，它不会受到任何伤害，也不会死亡。 这是我的PlayerShooting脚本。统一生存射手敌人无损伤 - Android
using UnityEngine;
using System.Threading;
using UnityStandardAssets.CrossPlatformInput;

{
public class PlayerShooting : MonoBehaviour
{
public int damagePerShot = 20; // The damage inflicted by each bullet.
public float timeBetweenBullets = 0.15f; // The time between each shot.
public float range = 100f; // The distance the gun can fire.

void Awake()

// Set up the references.
gunParticles = GetComponent<ParticleSystem>();
gunLine = GetComponent <LineRenderer>();

gunLight = GetComponent<Light>();
//faceLight = GetComponentInChildren<Light>();
}
void Update()
{
// Add the time since Update was last called to the timer.
timer += Time.deltaTime;
#if !MOBILE_INPUT

#endif

这里是我的EnemyHealth脚本。
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;
namespace CompleteProject
{
public class EnemyHealth : MonoBehaviour
{
public int startingHealth = 100; // The amount of health the enemy starts the game with.
public int currentHealth; // The current health the enemy has.
public float sinkSpeed = 2.5f; // The speed at which the enemy sinks through the floor when dead.
public int scoreValue = 10; // The amount added to the player's score when the enemy dies.
public AudioClip deathClip; // The sound to play when the enemy dies.
Animator anim; // Reference to the animator.
AudioSource enemyAudio; // Reference to the audio source.
ParticleSystem hitParticles; // Reference to the particle system that plays when the enemy is damaged.
CapsuleCollider capsuleCollider; // Reference to the capsule collider.
bool isDead; // Whether the enemy is dead.
bool isSinking; // Whether the enemy has started sinking through the floor.
void Awake()
{
// Setting up the references.
anim = GetComponent <Animator>();
enemyAudio = GetComponent <AudioSource>();
hitParticles = GetComponentInChildren <ParticleSystem>();
capsuleCollider = GetComponent <CapsuleCollider>();
// Setting the current health when the enemy first spawns.
currentHealth = startingHealth;
}
void Update()
{
// If the enemy should be sinking...
if(isSinking)
{
// ... move the enemy down by the sinkSpeed per second.
transform.Translate (-Vector3.up * sinkSpeed * Time.deltaTime);
}
}
public void TakeDamage (int amount, Vector3 hitPoint)
{
// If the enemy is dead...
if(isDead)
// ... no need to take damage so exit the function.
return;
// Play the hurt sound effect.
enemyAudio.Play();
// Reduce the current health by the amount of damage sustained.
currentHealth -= amount;
// Set the position of the particle system to where the hit was sustained.
hitParticles.transform.position = hitPoint;
// And play the particles.
hitParticles.Play();
// If the current health is less than or equal to zero...
if(currentHealth <= 0)
{
// ... the enemy is dead.
Death();
}
}
void Death()
{
// The enemy is dead.
isDead = true;
// Turn the collider into a trigger so shots can pass through it.
capsuleCollider.isTrigger = true;
// Tell the animator that the enemy is dead.
anim.SetTrigger ("Dead");
// Change the audio clip of the audio source to the death clip and play it (this will stop the hurt clip playing).
enemyAudio.clip = deathClip;
enemyAudio.Play();
}
public void StartSinking()
{
// Find and disable the Nav Mesh Agent.
GetComponent <UnityEngine.AI.NavMeshAgent>().enabled = false;
// Find the rigidbody component and make it kinematic (since we use Translate to sink the enemy).
GetComponent <Rigidbody>().isKinematic = true;
// The enemy should no sink.
isSinking = true;
// Increase the score by the enemy's score value.
ScoreManager.score += scoreValue;
// After 2 seconds destory the enemy.
Destroy (gameObject, 2f);
}
}
}
我已经把日志无处不在，发现从PlayerShooting脚本enemyHealth对象总是返回空，即使如果我打子弹的敌人。
需要知道为什么它总是返回null，如何使它比其他的空当我击中敌人。
做'的debug.log（shootableMask）'告诉我什么该值 – Programmer
值是512。@Programmer – Rohit
