[Network]When a barrel was explored another people can't see!

Hi i'm got some problems with network when i shoot a barrel i can see the explosion but another people i means other device is connected of my network can't see that! How can i resolve and i using uLink to implement of my project[IOS] Who have any idea or suggestion please help and this is my code of my barrel

var hp : int = 100; var detonationDelay = 0.0; var explosion : Transform; var deadReplacement : Rigidbody;

function ApplyDamage (info : String[]){ var damage : float= parseFloat(info[0]); // We already have less than 0 hitpoints, maybe we got killed already? if (hp <= 0.0) return;

 hp -= damage;
 if (hp <= 0.0) {
     // Start emitting particles
     var emitter : ParticleEmitter = GetComponentInChildren(ParticleEmitter);
     if (emitter)
         emitter.emit = true;

     Invoke("DelayedDetonate", detonationDelay);
     
 }

}

function DelayedDetonate () { BroadcastMessage ("Detonate"); }

function Detonate () { // Destroy ourselves Destroy(gameObject);

 // Create the explosion
 if (explosion)
     Instantiate (explosion, transform.position, transform.rotation);

 // If we have a dead barrel then replace ourselves with it!
 if (deadReplacement) {
     var dead : Rigidbody = Instantiate(deadReplacement, transform.position, transform.rotation);

     // For better effect we assign the same velocity to the exploded barrel
     dead.rigidbody.velocity = rigidbody.velocity;
     dead.angularVelocity = rigidbody.angularVelocity;
 }
 
 // If there is a particle emitter stop emitting and detach so it doesnt get destroyed
 // right away
 var emitter : ParticleEmitter = GetComponentInChildren(ParticleEmitter);
 if (emitter) {
     emitter.emit = false;
     emitter.transform.parent = null;
 }

}

// We require the barrel to be a rigidbody, so that it can do nice physics @script RequireComponent (Rigidbody)
