Title: Any way to tell if a UISlider is currently being dragged?
Post by: tydygunn on October 13, 2015, 01:28:52 PM

Hiya! NGUI's a lifesaver!

I'm building a scene with camera movement where the user can click and drag the mouse to rotate the camera. I've got it so when the mouse cursor is hovering above a UI collider it'll disable camera movement, but I'm having an issue with sliders. When you click and drag a slider, the cursor can move off the slider's collider area, therefore the camera's movement is allowed again even though the user is still dragging my UIScrollView's slider.

Do you have a technique I could use to check if a slider is in use? I've tried simply checking if UISlider.current != null, but that doesn't seem to be working. UISlider.current.isActiveAndEnabled doesn't work either, but I'm not 100% certain of the purpose of that bool so I didn't expect it to work in the first place. The slider is attached to a UIScrollView, so maybe I could check if that scroll view is being moved? I'm not sure how I'd do that.

Thanks for any advice you could give! Currently using NGUI 3.8.2.

UICamera.currentTouch.pressed tells you what you pressed it on. Don't just check for what it's currently over. Check for what it's pressed on first.
