Question

I have this function from an old Javascript I wrote. I want to reuse it in a new script written in C# (2nd script below). The script is assigned to the parent and its children. I need to tell the children that they are selected.

function OnMouseDown() {
    if (selected == false && ItemsRemaining.items > 0) { ItemsRemaining.items--; }
    selected = true;
       var scan = transform;
       while(scan.parent && scan.parent.GetComponent.<Hazard>() != null)
              scan = scan.parent;
       for(var hazard : Hazard in scan.GetComponentsInChildren.<Hazard>())
              hazard.selected = true; 

}

 void OnMouseDown()
 {
 if(!ObjectSelected)
 {
 var scan = transform;
        while(scan.parent && scan.parent.GetComponent<IdentifiableObject>() != null)
             scan = scan.parent;
        Transform[] allChildren = GetComponentsInChildren<Transform>();
 foreach (Transform child in allChildren)
 child.ObjectSelected = true; //NOT WORKING

 }
 }

Given you are using the two different languages you are best of sending a message to the other script and passing the value.

    SendMessage("Selected", true);


   ...

Child:

  void Selected(bool selected)
  {
        ObjectSelected = selected;
  }

When you use scripts in different languages it is hard to integrate them as they are compiled separately.

I'm not using the scripts together. I'm wanting to re-use a feature from the *.js in a C# script.

So you are dumping the JS?

In that case you want to get the component in the foreach loop

  child.GetComponent<ScriptNameGoesHere>().ObjectSelected = true

Thanks, that did the trick. I added the same to the "scan" variable so that if the child is selected, it can tell the parent to be selected too.

Here is what I have now. When the parent object is hovered, it highlights all the children. When a child is hovered, it highlights itself and the parent but not the other children. What am I missing, so that all children are highlighted when one child is mouseovered?

void OnMouseOver()
 {
 if(!ObjectSelected)
 {
 var scan = transform;
    while(scan.parent && scan.parent.GetComponent() != null)
 {
         scan = scan.parent;
 scan.renderer.material.color = hoverColor;
 }
    Transform[] allChildren = GetComponentsInChildren();
 foreach (Transform child in allChildren)
 child.renderer.material.color = hoverColor;
 }
 }

 void OnMouseExit()
 {
 if(!ObjectSelected)
 {
 var scan = transform;
    while(scan.parent && scan.parent.GetComponent() != null)
 {
 scan = scan.parent;
 scan.renderer.material.color = currentColor;
 }
    Transform[] allChildren = GetComponentsInChildren();
 foreach (Transform child in allChildren)
 child.renderer.material.color = currentColor;
 }
 }

 void OnMouseDown()
 {
 if(!ObjectSelected) 
 {
 var scan = transform;
    while(scan.parent && scan.parent.GetComponent() != null)
 {
         scan = scan.parent;
 scan.GetComponent().ObjectSelected = true;
 }
    Transform[] allChildren = GetComponentsInChildren();
 foreach (Transform child in allChildren)
 child.GetComponent().ObjectSelected = true;
 }
 }
