// first config part.LOL

var s = ccbGetSceneNodeFromName("soldier");
var otherNode = ccbGetSceneNodeFromName("Camera1");

// now this **** comes.
// if the enemy comes to the activation area then, execute the code
// cancel everything

ccbAICommand(s, "cancel"); // this line does't works, even i come to the activation range, the soldier just walks randomly till it reaches random point to where it has to go

// now keep on shooting the enemy
// if the enemy dies then call other members of the troop to that area in order to make is just like real

if (Camera1.health == 0) {
// if the player is dead, then call other members.
call_troop();
} else {

//loop till the player dies
for (; Camera1.health = 0;) { 
ccbAICommand(s, "attack", otherNode);
}
}

You have-
for (; Camera1.health = 0;) { 
ccbAICommand(s, "attack", otherNode);
}

when it should be

for (; Camera1.health>0;) { 
ccbAICommand(s, "attack", otherNode);
}

But a better way would to be


while(Camera1.health>0)
{
   ccbAICommand(s, "attack", otherNode);
}

Camera1.health>0 it should be otherNode.health>0
