ScrollView - How to stop infinite scrolling?

Questions & Answers

So I’m having the Unrestricted MoveType Scrollview (Only Vertical), Inside I’m having the VerticalLayoutGroup filled with buttons. But the problem is that user can scroll into infinity. I want to stop scrolling when the last button is at the bottom of the view. How do I achieve that?

How to stop infinite scrolling in scrollview ?

It’s a little hard, not impossible, what we are going to do, is set the maximum value to the amount of buttons like this…

int buttonSize = 80;
int numberOfButtons = 4;
int mValue = buttonSize*numberOfButtons;

In a scrollview, the content need to put in this GameObject → ScrollView>Viewport>Content.
The content recttransform is changed when you scroll stuff. We can’t let it’s TOP value be higher than 0, so we do this:

public RectTransform cont;

void Update(){
	if(cont.offsetMax.y < 0) { //It seems that is checking for less than 0, but the syntax is weird
		cont.offsetMax = new Vector2(); //Sets its value back.
		cont.offsetMin = new Vector2(); //Sets its value back.
	}
}

Now we can’t let the value be higher than the number of buttons, so we do this:

if(cont.offsetMax.y>(numberOfButtons*buttonSize)-buttonSize) { // Checks the values
	cont.offsetMax = new Vector2(0,(numberOfButtons*buttonSize)-buttonSize); // Set its value back
	cont.offsetMin = new Vector2(); //Depending on what values you set on your scrollview, you 			 								might want to change this, but my one didn't need it.
}

Hope this helps :slight_smile:
