Question by FortisInvictus · Sep 24, 2015 at 01:49 PM · 2dalphaprevent

Pass clicks through transparent places in image

Hi!)

I have complex image with transparent pixels in different places of image and buttons behind of this image. Is there any way to prevent clicks through this image only on pixels with alpha = 1?

Thanks!

You could use GetPixels, then find out which pixel on the image the mouse cursor is over, and check if that pixel's color's alpha value is 1.

Understood! What about ScrollView which has Horizontal Layout Group with buttons inside, and image with transparent hole in center. Is it posible to prevent clicks through pixels with alpha = 1? I`ve got pixel with alpha = 1 and then disabled CanvasGroup (bottomCanvGroup.blocksRaycasts = false), but first click passed through. $$anonymous$$aybe, you have some ideas)
