How to disable just the slider or any element in the ngui in code...

[sk1989]

Hi, I just want to know how to disable and enable slider.


normally in unity you can disable things by setting the enabled to false.

just wondering how to do it for NGUI elements.

Thanks in advance...

When you say "disable" do you mean:

A)  Make them inactive so they do not respond to input, yet are still visible or

B)  Deactivate and hide them.

NGUITools.SetActive(sliderGameObject, false).

How would you go about making the slider visible and generate OnHover() events, but not respond to mouse clicks? I'm using them for health bars, but the sliders' inherent ability to be adjusted using the mouse interferes with that somewhat. 

[ArenMook]

Put the collider on the background sprite instead of the slider, and do your OnHover handling there. If you need, forward press events to the actual slider game object.

It works but boy, does it create convoluted code, especially since I have numerous sliders in the same panel. There's no better way? No way, to just tell the slider to ignore mouse presses and drags?

[ArenMook]

Slider script was designed with event handling in mind. You could write your own slider that does exactly what you need it to. Use the slider code as the template.

Just sent you an expanded version of the UISlider that allows people to turn user interaction on and off through a Toggle in the Editor. Hope you can use it.

You are welcome to post those two files here as an attachment in case someone else needs this functionality.

Here are expanded versions of NGUI's UISlider component. This version has a toggle in the Inspector to make it static, which means that the user will not be able to manipulate it with the mouse or keyboard. Unlike simply removing the collider from the object to achieve the same result, this version still generates an onHover event, making it perfect for bar graphics, such as health bars, etc. where additional information, such as the actual points) can be displayed as an OnHover tooltip.

Note: These files replace the original files, which means that they will be overwritten by the next NGUI update in your Assets folder, unless our friend Arenmook should decide to actually make these expanded versions part of the package. *hint* *hint*
