Unity4.6 - Setting text Property on Text Object

Questions & Answers
1

Hi,

I’m new to uGUI in 4.6 and I’m hitting a peculiar issue after instantiating a gameObject from a prefab. I have a prefab which is an empty GameObject with a Text object underneath it, hierarchy as follows;

GameObject

→ Text (uGUI)

The intent is that I can instantiate a number of these objects in specific areas of the worldspace such that I can have floating labels around the world. The world is made up of a particle system and it is individual particles I’m trying to label, in this case each one representing a vessel at sea.

This is the code that I’m having issues with;

if (visibleVessels.Count > 0)
            {
                //  for each vessel, create a label
                GameObject[] labels = new GameObject[visibleVessels.Count];
                for (int i = 0; i < visibleVessels.Count; i++)
                {
                    labels *= (GameObject)Instantiate(vesselLabel);*

labels_.transform.position = GenPosition(visibleVessels*, worldFlat, globalOffset);_
_labels.transform.SetParent(labelCanvas.transform, true);
labels.GetComponent().text = visibleVessels.Name.ToString();
}
}*
visibleVessels is a list of positions, I get the correct number of labels on the screen however then I try to set the text value I get "Object reference not set to an instance of an object.
Is there a new way to address components I’ve missed or am I barking up the wrong tree?
Any pointers would be greatly received.
Regards,
Keegan_

Well, assuming that with the following line

labels *= (GameObject)Instantiate(vesselLabel);*

You instantiate this prefab you described which is a GameObject with a Text component on his child.
Then you should change this
labels*.GetComponent().text*
To this
labels*.GetComponentInChildren().text*
