GetComponentInChildren with tag in two variable

Question

Hello, for my problem I obviously look on the internet before coming here you ask the question. But when I use GetComponentInC$$anonymous$$ldren <> it gives me the component of the first c$$anonymous$$ld but I want all the composent of the c$$anonymous$$ldren.

I want take the component and place it in two variable named left and right.I want two variables with different c$$anonymous$$ldren to control my side shooting with boolean: Code to take component ShootCanonFront:

     ShootCanonfront left;
     ShootCanonfront right;
 
     void Start () {
         left = GameObject.FindWithTag("LeftBoat1").GetComponentInC$$anonymous$$ldren<ShootCanonfront>();
         right = GameObject.FindWithTag("RightBoat1").GetComponentInC$$anonymous$$ldren<ShootCanonfront>();
     }
     
     void Update () {
         
     }

alt text

So my question is: How can i take ShootCanonFront components of c$$anonymous$$lds Left object and place it to left variable and do the same for right variable. I hope it's understandable and thanks in advance ^^

Good day.

For one side you have GetComponentsInC$$anonymous$$ldren () , ComponentS, with S

T$$anonymous$$s gives you an array of that type of components. for example, a script called "GoodScript"

 GoodScript[] MyScripts= [.bla bla...].GetComponentsInC$$anonymous$$ldren<GoodScript>();

Now you have an array of all GoodScript s in the array called MyScripts.

By the other side, i recommend you , as there are only 2 components to find, to reach each object 1 by 1 with

 gameObject.transform.Find("C$$anonymous$$ld Name").GetComponent();

and get directly the components.

Byee!ª

:D

Use

 ShootCanonfront[] left;
 ShootCanonfront[] right;
 
  void Start () {
      left = GameObject.FindWithTag("LeftBoat1").GetComponentsInC$$anonymous$$ldren<ShootCanonfront>();
      right = GameObject.FindWithTag("RightBoat1").GetComponentsInC$$anonymous$$ldren<ShootCanonfront>();
  }

Hello, when i try this i have an error and i can access to the variable of ShootcanonFront. Thank to you anyway :) This error:`error CS1061: Type ShootCanonFront[]' does not contain a definition for isNowShooting' and no extension method isNowShooting' of type ShootCanonFront[]' could be found. Are you missing an assembly reference? `

It's a collection, so you have to step through it in a loop. Use a for or foreach, whichever you're comfortable with:

 for (int i = 0; i < left.Length; ++i)
 {
     // Prints the name of the object containing the component
     Debug.Log(left[i].name);
 }

or

 foreach (ShootCanonfront scf in left)
 {
     // Prints the name of the object containing the component
     Debug.Log(scf.name);
 }

Do also make use of the scripting reference: https://docs.unity3d.com/ScriptReference/Component.GetComponentsInChildren.html

Sorry but it's the same. I have the same error, i can't access to my variable isNowShooting. My whole code:`

ShootCanonFront[] left; ShootCanonFront[] right;

void Start () { left = GameObject.FindWithTag("LeftBoat1").GetComponentsInChildren(); right = GameObject.FindWithTag("RightBoat1").GetComponentsInChildren(); foreach (ShootCanonFront scf in left) { Debug.Log(scf.name); } rgBoat = GetComponent(); health = startHealth; }

  void Side()
 {        
     //Change side of boat
     if (Input.GetKeyDown(KeyCode.E))
     {
         SelectedArm += 1;
         if (SelectedArm == SelectedArmLeft)
         {
             left.isNowShooting = true; right.isNowShooting = false;
         }
         if (SelectedArm == SelectedArmRight)
         {
             left.isNowShooting = false; right.isNowShooting = true;
         }
         if (SelectedArm > SelectedArmRight)
         {
             SelectedArm = SelectedArmLeft; left.isNowShooting = true; right.isNowShooting = false;
         }
     }
 }

 Error:error CS1061: Type `ShootCanonFront[]' does not contain a definition for `isNowShooting' and no extension method `isNowShooting' of type `ShootCanonFront[]' could be found. Are you missing an assembly reference?`

Hi,
Try and use the following code.
{
List leftList = new List();
List rightList = new List();

ShootCanonfront[] left;
ShootCanonfront[] right;

void Start()
{
Transform leftBoat1 = GameObject.FindWithTag("LeftBoat1").GetComponentInC$$anonymous$$ldren();
Transform rightBoat1 = GameObject.FindWithTag("RightBoat1").GetComponentInC$$anonymous$$ldren();

 foreach(Transform c$$anonymous$$ld in leftBoat1)<br />
 {<br />
     leftList.Add(c$$anonymous$$ld);<br />
 }<br /><br />

 foreach(Transform c$$anonymous$$ld in rightBoat1)<br />
 {<br />
     rightList.Add(c$$anonymous$$ld);<br />
 }<br /><br />

 left = leftList.ToArray();<br />
 right = rightList.ToArray();<br />

}
}
