Viewpoints are these purple things.

To implement them, add ViewPoint to this switch here in EntityGadget.buildContent: You will then need to make GadgetViewPoint.java that matches those other gadget types.

in onInteract(), you need to read the groupId and the ConfigId by doing something like:

        var entity = player.getScene().getEntityById(req.getGadgetEntityId());
        if(entity instanceof EntityGadget entityGadget){
            var groupId = entityGadget.getOwner().getGroupId();
            var configId = entityGadget.getOwner().getConfigId();
        }

You then look up this groupId and configId in ViewCodexExcelConfigData:

    {
        "Id": 70200016,
        "gadgetId": 70800028,
        "sceneId": 3,
        "groupId": 133107133,
        "configId": 133001,
        "nameTextMapHash": 3607590626,
        "descTextMapHash": 325052640,
        "image": "UI_Codex_Scenery_LYfeiyunpo",
        "cityId": 2,
        "worldAreaId": 2701,
        "SortOrder": 102
    }

All you care about is Id. pop that Id into a PacketCodexDataUpdateNotify and bob is your uncle: (7 is a CodexType of CODEX_TYPE_VIEW)

player.getScene().broadcastPacket(new PacketCodexDataUpdateNotify(7,Id));
