GUITexture: border parameters

How can I access by script the GUITexture border parameters (left border, top border....)?
Thanks

Antonio

 

I fear you're right. Now I'm really stuck as I have to model through a GUITexture a life bar drecreasing right to left. I will appreciate a word from OTEE guys: is there a workaround to achieve this?
Thanks

 

There are numerous ways to do life/health bars that don't require _scripted_ access to the border properties. Perhaps you can explain why lack of script access is a barrier and then we can advise on how to deal with that?

FYI: I too find it odd that you can't access those properties and after chatting with Sam about it we'll file a bug about this (unless someone has already? if you have then please let me know the bug ID number - either here in this thread, via PM or email).

 

Hello Higgy, thanks for your reply.
We found out that buy using the border values in conjuction with pixel inset values you can achieve UV scaling on a GUITexture. Since we have to model a life bar, decreasing right to left as the player gets damaged, we've though this to be the ideal solution. We haven't filed any bug; will appreciate if you could do that. Cheers,

Antonio

 

Not a problem Antonio, I'll handle logging a bug about this one. The question still remains though, do you need a workaround for something here? Sure you don't have scripted access to the border values, but you can manually set them in Unity and go from there. If you need various border values then perhaps you can make a prefab GUI Texture for your various border value combinations? Let us know if you need any help sorting out how to proceed given this limitation, otherwise we'll just assume you're off and running.

Me? I'm off to log that bug now...

 

I ran into the same problem today, but I have a workaround for my use, that only involves duplicating some info.

Another way to solve Antonio's original task, a healthbar with texture decreasing from right to left, would be
- model the healthbar as a plane in 3D
- as the bar decreases:
--- scale the size of the plane down, using e.g. transform.localScale
--- scale the texture of the plane material up, using e.g. renderer.material.mainTextureScale
--- there should be no need to manipulate the offset, but if necessary it could be done with renderer.material.mainTextureOffset

 

Hey,

Did this ever get done? I mean exposing the border properties to scripting?

Was that bug ever posted?

I could really use this feature right about now

ADDENDUM:

I filed a bug. Case 363854.

FURTHER ADDENDUM:

I have discovered that one can work around this issue by using code-generated gui elements with GUIStyles.
Here's the procedure:

1. Place desired image as the 'normal background' of the GUIStyle.
2. Write a GUI.Label in a script's OnGUI function which uses the GUIStyle.
3. Access the border properties of the GUIStyle as noted in the documentation.
4. You will notice the desired effect on your image.

I must note here that this is a workaround; the functionality should really be exposed in the GUITexture class. I can't imagine why this hasn't been fixed by now. It seems like a really simple thing to do, and in a lot of cases using GUITexture as a component is preferable to using OnGUI.

In case anyone is interested in doing a standard health-bar type effect, the solution (using this method) is to set the 'width' and the 'left border' simultaneously to the same value, which of course should usually be:

= health% * fullBarLength;

 

@nerophon : Good trick, works great! Now I can finally implement a decent life bar! Thank you! You saved my life(bar)! I love you! Would you marry me?

(Err, forget about the last two sentences. But still a great trick.)

 

Has this issue ever been address? We just run into this problem, and even though there are work arounds, for those who prefer not to use GUI functionality would be a great improvement to have access to borders from a scripting point of view.

Cheers.

EDIT: Or having access to UV on GUITextures would be great too, but I guess that is a more complicated issue, as HiggyB already confirmed borders should be accessible.

 

Did this ever get done? I just stumbled upon it too.

A bit silly since this bug apparently exists since 2007

 

@nerophon

Thanks for the hint, nice work!
I've tried to find a way to do that for days, and now it's done.
It's sad that all of this has to be done for a simple task, on a robust Engine like Unity, but, it's done.
I'm looking forward to see this bug solved.

I have same problem and can't use GUI.Label. Is there any other way to make progress bar with GUITexture? I guess this bug wont be fix

 

Just chiming in here on this also. Such a simple little thing and its causing me no end of problems. I know there are work around solutions here but it would be so much easier to just expose the required varaibles as public. I dont want to use OnGUI because of the associated preformance hit, especially for the 1 or 2 words that I was planning to use in the Speach bubble i've created. Please fix this 4 year old bug!

 

I'm on this too.
I want to use GUITexture to do variable amount of miniatures and cut leftover by using width and border. Testing in editor worked well, but now I can't do it by code.
Seems GUITexture is recommended way to do interface on iOS because of performance, but then is too limited (can't make a simple offset-atlas too…) :-?

 

will this ever be fixed? i would like to acces this trough scripting.. because i create GUITextures in script. need the borders..
just acces it trough "guiTexture.leftBorder" or something like that.. or a Rect. Good luck unity people with creating this
it is realy weird, that after 5 years of knowing this problem... that there's not a normal fix for this.

 

So when exactly is Unity 4.0 releasing since I'm hitting the same issue as the original 5yo post?

 

I need too modify by scripting these borders properties...I will try nerophon workaround

PD
It has not been implemented yet on Unity 3.5.5f3

 

Ok - so this appears to be an ANCIENT bug - and I have just ran up against this as well. I'm working in Unity 4.x and currently attempting to manipulate the border of a GUITexture. I've noticed there is now a GUITexture.border.Remove() function that accepts a Rect as an argument, but no matter what I feed it, I am unable to manipulate the border values of the Texture in question.

Kuba, or any other Unity Developers - can we get a chunk of example code with this functional?

 

So - for any of you wondering how to do this; after digging for a bit longer I was able to discover that the RectOffset class can actually accept direct parameters for left,right,top, bottom.

I admit I feel very stupid having found this out for my first post - but figured I'd post a little chunk of code here that would help anyone else out that found themselves in this predicament. (In C#)

Code (csharp):

1. RectOffset tempOffset = new RectOffset(leftValue, rightValue, topValue, bottomValue);
2. gameObject.GetComponent<GUITexture>().border = tempOffset;
3.  

This will effectively "set" your border for your GUITexture to your desired values.

Apologies again for the 1st post - but the answer wasn't entirely clear at first.

 

thanks , that absolutely true and work for me ,this answer should be highlighted
