Ugui learning notes (II) Scrollview related

      Learning to ScrollView When I met a small pit . Take a note .

           The hierarchy is shown in the figure .

      This scrollpanel I created an empty object myself and dragged it ScrollView Script for , Added a image and mask. Under it, a grids, The script mounted above is shown in the figure

     GridLayoutGroup It's like a container , The sub objects under it will be automatically arranged . except GridLayoutGroup Besides VerticalLayoutGroup and HorizontalLayoutGroup. The specific interface of the layout can be modified by modifying the parameters on the panel . The specific effect can be tried out, so I won't say much here .ContentSizeFitter It is used to automatically calculate the spacing of each element . In dynamic generation UI There is no need to set the interface manually . among RectTransform Of H Delta This value will affect grids Sliding range of . Because of the addition of ContentSizeFitter This component cannot be modified manually .

      The point is scrollpanel The components mounted on . Pictured

     content Drag into the parent object of all elements you want to slide Here is grids. The following two buttons are used to choose whether to slide horizontally or vertically . Then there is the sliding type , You can try each effect by yourself . Next is the recovery time , inertia . I'm not very clear about the next two parameters .Viewport Can be null . It's not clear exactly what happened . Then there are vertical and horizontal sliding bars . It can also be empty .mask Used for masking .

    That's basically it . Then talk about the pit I encountered .

      I was in Hierarchy Create an empty object directly on the panel, and then put ScrollRect Added by components . You will encounter Mingming adjustment grids But a run grids It will bounce back to its original position and grids Obviously, there is still a long problem that can't be delayed . I consulted the boss and solved it for a long time .. But I don't know how to solve it .. But it is said that the key point is RectTransform On .scrollpanel Upper RectTransform Of Height Is with the grids The initial position of the runtime .grids It's very long but can't drag. It's related to grids Of bottom namely HDelta of .

      But none of this matters .. Because just direct

      This creates a ScrollView There will be no pit I just said ..

      That's about it . Then I will add others .
