For a progress bar You can use the Unity scrollbar object to make what you're looking for. There's a good tutorial on it here [LINK] . Essentially, you add a scrollbar object to your canvas, and then change the slider value from code. For scrolling textures If you want a scrolling texture on your progress bar, then you can animate an image placed on the slider. If you don't want to animate it by hand, then it's a little more complicated. Ideally you could set the texture offset of the image in code to get it to scroll, but after looking it up I don't think that Unity allows you to do that on non-3D objects. If you still want it to scroll and don't want to make a hand-drawn animation for it,

You can do this with masking for the visual part, and Canvas Groups for the interaction part. For the visual part, see Unity's official UI Mask tutorial [this video] . As for the interaction part, I am not completely sure this works, as I haven't done it myself, but according to the Unity documentation, you should be able to do it with Canvas Groups [LINK] . Have a parent canvas group with the Block Raycasts flag set to true (marked), and then, for the non-blocking area use a second canvas group with the Block Raycasts flag set to false (unmarked), and the Ignore Parent Groups flag set to true (marked). The second group should thus override the parent group's blocking behaviour.

Hi I am using mask in unity and now I want to get the masked texture and save as a png file. Unity Mask [this video] For example, in this video, I want to get the masked image instead of the whole background image or the mask texture. I tried (GetComponent<Mask>().graphic.mainTexture as Texture2D).GetPixels() but it doesn't work. Thank you very much.
