GUIText Instantiation and Update the Instantiated Text. C#

Question

Hello,

What I am trying to do is instantiate the damage you do on an enemy and render the damage you did on the text that is instantiated. Here is the script I am working on. I have tried multiple methods that I thought might work, but thus far no success. Unity Answer folk to the rescue?

 private GUIText GUIDamage;
 public GameObject GUIPrefab;
 
 void Damage ( float damage  ){
       GameObject GUIDamage = Instantiate(GUIPrefab, Camera.main.WorldToViewportPoint(gameObject.transform.position), Quaternion.identity);
     GUIDamage.guiText = Shooting.damageToSend;
     }

Currently I have gotten various errors with various methods of trying to get it to work. I have seen a similar script on Unity Answers about t$$anonymous$$s, but it was in that nasty Unityscript. :O

The current error I recieve is : " Cannot implicitly convert type UnityEngine.Object' to UnityEngine.GameObject'. An explicit conversion exists (are you missing a cast?)" I t$$anonymous$$nk I know why I get t$$anonymous$$s, I just don't know how to get the code to work without errors haha.

Cheers, Thank you for your time.

The problem is that you are trying to define GUIDamage twice, as different types!

First, here-

 private GUIText GUIDamage;

then, here-

 GameObject GUIDamage

Not only will t$$anonymous$$s cause issues with one $$anonymous$$ding the other, I doubt that that is actually what you want.

In t$$anonymous$$s case, you should stop trying to re-define GUIDamage. It's defined correctly the first time, there's no need to define it again (and it would disappear at the end of the scope if you did anyway).

Instead, use GetComponent to grab the GUIText out of the newly instantiate object, and then you can refer to GUIDamage in Update to modify the text!

 GUIDamage = ((GameObject)Instantiate(GUIPrefab, Camera.main.WorldToViewportPoint(gameObject.transform.position), Quaternion.identity)).GetComponent<GUIText>();

Would love to thumbs up but I'm new, I wanted to show points on screen when an asteroid was blown up and couldn't find an example of how to position it correctly so answered multiple questions with this answer!

Hi guys,

I've finished going through the Space Shooter/Asteroids tutorial and now I am trying to tweak the game to keep learning.

I am trying to do what tapticc mentioned above and have the points for a destroyed asteroid flash up on the screen at the location of the exploding asteroid. I have played around with the above code but with no luck.

Would it be possible to get a larger code snippet that shows how this should work?
