用于创建Item列表的组件,支持三种创建方式:
|
|
)传入Item类名:使用字段item_class
|
|
)传入prefab资源名:使用字段prefab_ab_name和prefab_res_name
|
|
)对象池类型如:UIObjPool.UIType.AwardItem:使用字段obj_pool_type
|
|
)单个控件如：UIType.Label使用字段ui_factory_type
|
|
各字段使用说明:
|
|
data_list:子节点的信息列表
|
|
create_frequency:分时加载,即每隔这么多秒加载一个子节点
|
|
item_con:装载子节点的容器节点
|
|
scroll_view:滚动容器节点(带ScrollRect组件的那个),如果不是滚动容器的话此值设为和item_con一样即可
|
|
item_width:单个子节点的宽度, item_height为高度
|
|
get_item_width:如果你的子节点们不是同一大小，这时就需要传入该回调用于查询每个子节点的大小,get_item_height同理，设定后还需要指定reuse_item_num字段，因为子节点是动态的了，我帮不了你预先计算可视区域里最多可显示多少个子节点
|
|
space_x:子节点间的水平间隔, space_y为垂直间隔
|
|
start_x:子节点的初始偏移,start_y同理
|
|
show_col:显示的列数, 暂不支持控制行数
|
|
on_update_item:子节点刷新事件的回调
|
|
reuse_item_num:复用子节点的数量,为nil或大于0时开启,默认是开启的,一般不需要手动指定（除非你的子节点大小是动态的）,默认情况下将只创建可视区域里可见的最少数量节点,当子节点超出可视区域时会复用它填补到可视区域
|
|
alignment:对齐方式,目前只支持左上角,水平居中,垂直居中,当非左上角布局时优化选项无效(即reuse_item_num为0),有空再兼容处理吧
|
|
child_names:仅当prefab_ab_name和prefab_res_name有值时才有效,指定子节点的子节点们的名字集
|
|
fitsize_scroll_view:是否把滚动容器的大小设为刚好容纳子节点们的大小
|
|
is_scroll_back_on_update:是否每次设置的时候重置滚动容器坐标
|
|
final_callback:延迟创建第一次创建完item之后是否需要回调
|
|
force_hide:强制使用SetActive，不走SetVisible的优化，对子节点有角度修改时使用
|
|
mask_end_to_first:屏蔽掉 滚动到末尾的时候会显示第一个节点的逻辑
|
