Search and get parameters of a sub-gameobject in Canvas

Hi all

Honestly I did not want to open this discussion, but I searched the whole forum and did not find anything that would really help me. The nproblem is:

I've a empty gameobject that which contains multiple canvases (image below) and it turn on and off the whole group:



Now ignoring how to get to take and use a component, I have the problem of using a sub-object such as the test highlighted in the image. Practical example:

- I've a Cube object with with an attached script that contains an explanation for the cube itself
- I've a Player that collide with the Cube and active the script/cube
- With GameObject.Find metod, I check the sub-gameobject

Code (CSharp):

1. textHelp = GameObject.Find("ItemHelp_Text").GetComponent<Text>();

Now the problem is born, I can't associate the cube description script with "ItemHelp_Text" canvas, or I can't get into its parameters

Where am I wrong? What to do? what did I miss? I've been trying for a few days and I think I've "wrapped up"

EDIT: Sorry for double post, but I've forgot a second question: The cube script that contains the text is inserted into a function. When I call it I've the error that does not allow me to transform the void in string. In this case how to act?

 

I'm not myself really good in English but I think you're not very understandable here.

Whare are you trying to do?

Get the UI Text component of a specific gameobject and access its variables and methods?

 

Yes, but above all enter the sub-levels and access the parameters etc (you see the image attach. In other circumstances normally do not have problems accessing the parameters access, but in the above example I do not understand..

 

Sorry for the UP, but nothing tip from community?

 

Hi @MedalHellWay

The question is really vague, maybe you could rephrase it so it's more understandable.

There is nothing wrong with how you get your Text component, what else are you trying to do?

What do you mean by:

"I can't associate the cube description script with "ItemHelp_Text" canvas, or I can't get into its parameters"

Are you trying to get the canvas where ItemHelp_Text is or what do you mean?

To change text of ItemHelp_Text, just do:

Code (CSharp):

1. textHelp.text = myTextData;

To get some ui element's parent canvas do something like this:

Code (CSharp):

1. myParentCanvas = this.GetComponentInParent<Canvas>();    

But I have no idea what you are trying to do.

 

Ok, I try to explain myself better. Sorry if I've not been clear

I've a Cube with an attached script that describes it. When I collide him with my Player, the description must appear in the canvas.
So to improve performance in Unity, I have used more canvas for every use I've to make and grouped them under an Empty GameObject. The image below shows the result:



Now, I've no problem show the text in video during the test, but when I try to transfer it to Canvas, I have problems accessing its components, and I can't understand out where I'm wrong.

So with .Find method I can access the text in the canvas...

Code (CSharp):

1. textHelp = GameObject.Find("ItemHelp_Text").GetComponent<Text>();

but with

Code (CSharp):

1.  textHelp.text

I can not log in the canvas text. Surely I'm wrong somewhere, but I can not understand..

I hope I have been clearer and If you want, I have attached the test scene to make you understand how I am operating ...

EDIT: there is a bit of confusion in the test scene, but it's my way of working unfortunately !!

 

You create a unstable solution if you use the scene hierarchy to communicate between domains. It's better to use some kind of event bus and or command bus.

 

So, directly deduct the gameobject in the Inspector? ...or what do you mean exactly?

 

Build your own structure ontop of the gameobjects that does not rely on their structure at all, except maybe close to the metal.

 

Thanks for quick reply I thought to use an empty gameobject to turn off and turn on all the canvas quickly ... so it's wrong?

 

No, it's not wrong but how depend on it can be less optimal

 

Thanks for the tip
