cocos creator项目基础类库，包括socket, http网络连接，资源加载与管理，ui加载与管理，事件系统，音效播放，常用控件如listview，scrollview等
使用说明
1.ListView, 循环滚动列表，固定尺寸item, 屏幕可见范围外item会回收等待下次复用。支持横向，竖向，多行多列。
* 初始化，传入item模板节点(cc.Node)，设置各种回调函数
```
@property(cc.ScrollView)
scrollview: cc.ScrollView = null;
@property(cc.Node)
mask: cc.Node = null;
@property(cc.Node)
content: cc.Node = null;
@property(cc.Node)
item_tpl:cc.Node = null;
private list:ListView.ListView;
on_show(...params)
{
this.list = new ListView.ListView({
scrollview:this.scrollview,
mask:this.mask,
content:this.content,
item_tpl:this.item_tpl,
cb_host:this,
item_setter:this.list_item_setter,
select_cb:this.list_item_onselect,
recycle_cb:this.list_item_onrecycle,
column:1,
gap_y:10,
direction:ListView.ListViewDir.Vertical,
});
this.list.set_data(Consts.AllStages);
}
```
* 设置item回调函数
```
list_item_setter(item:cc.Node, desc:Consts.StageDesc, index:number):void
{
const isOpen = appdata.getStageOpenState(desc.stage, desc.unlockcond, desc.total);
const isPassed = appdata.isStagePassed(desc.stage, desc.total);
const cond = item.getChildByName("cond");
const txt_cond = cond.getChildByName("txt_cond");
const txt_progress = item.getChildByName("txt_progress");
const btn_share = item.getChildByName("btn_share");
const img_star = item.getChildByName("img_star");
const gold_star = img_star.getChildByName("gold_star");
//省略
}
```
2.ScrollView, 循环滚动列表，支持不定尺寸的item, 屏幕可见范围外item会回收等待下次复用。支持横向，竖向, 但不支持多行多列。
* 初始化，传入item模板节点(cc.Node)列表，设置各种回调函数
```
const templates:ScrollItemTemplate[] = [
{key:MsgType.ROUND_START.toString(), node:this.item_roundstart},
{key:MsgType.LEFT_REDPACK.toString(), node:this.item_leftpack},
{key:MsgType.RIGHT_REDPACK.toString(), node:this.item_rightpack},
{key:MsgType.GRAB_NOTIFY.toString(), node:this.item_grab},
{key:MsgType.ROUND_END.toString(), node:this.item_common},
{key:MsgType.ROUND_RESULT.toString(), node:this.item_roundresult},
{key:MsgType.LEFT_CHAT.toString(), node:this.item_leftchat},
{key:MsgType.RIGHT_CHAT.toString(), node:this.item_rightchat},
{key:MsgType.JOIN_ROOM_NOTIFY.toString(), node:this.item_common},
{key:MsgType.QUIT_ROOM_NOTIFY.toString(), node:this.item_common},
{key:MsgType.DISMISS_ROOM_NOTIFY.toString(), node:this.item_common},
{key:MsgType.ROUND_TIMEOUT_NOTICE.toString(), node:this.item_common},
];
this.scview = new ScrollView({
scrollview:this.scrollview,
mask:this.mask,
content:this.content,
item_templates:templates,
cb_host:this,
item_setter:this.item_setter,
recycle_cb:this.list_item_recyle,
gap_y:10,
auto_scrolling:true,
direction:ScrollDirection.Vertical,
});
```
* 设置item回调内部根据传入的key及data为对应item节点设置数据
```
item_setter(item:cc.Node, key:string, data:any, index:number):[number, number]
{
const enum_key:number = parseInt(key);
switch(enum_key)
{
case MsgType.ROUND_START:
item.getComponent(cc.Label).string = format.sprintf("第%d轮开始", data);
return [item.width, item.height];
case MsgType.LEFT_REDPACK:
case MsgType.RIGHT_REDPACK:
return this.set_pack_item(item, data);
case MsgType.ROUND_RESULT:
let node_names:cc.Node = item.getChildByName("names");
node_names.getComponent(cc.Label).string = data;
item.height = node_names.height - node_names.y;
return [item.width, item.height];
case MsgType.LEFT_CHAT:
case MsgType.RIGHT_CHAT:
return this.set_chat_item(item, data);
case MsgType.GRAB_NOTIFY:
return this.set_grab_item(item, data);
case MsgType.DISMISS_ROOM_NOTIFY:
case MsgType.ROUND_TIMEOUT_NOTICE:
case MsgType.JOIN_ROOM_NOTIFY:
case MsgType.QUIT_ROOM_NOTIFY:
case MsgType.ROUND_END:
item.getComponent(cc.Label).string = data as string;
return [item.width, item.height];
default:
return [0, 0];
}
}
```
* 追加数据, 传入key及item数据
```
const notify:pb.IRoomChatNotify = resp.roomChatNotify;
const key:number = notify.sender.acc == appdata.user.acc ? MsgType.RIGHT_CHAT : MsgType.LEFT_CHAT;
let data:ScrollItemData = {key:key.toString(), data:notify};
this.scview.append_data(data);
```
3.TweenUtil, 缓动工具
* 传入节点，用时，延时，要变动的属性, 曲线函数
```
let tween = TweenUtil.to({
node:coin, duration:0.8, delay:delay, x:dest_pos.x, y:dest_pos.y, tweenFunc:TweenFunc.Sine.easeIn,
onComplete:utils.gen_handler(this.on_fly_to_dest, this)
});
```
* 取消缓动
```
TweenUtil.kill(tween);
```
4.TimerMgr, 定时器
* 无限循环
```
TimerMgr.getInst().loop(0.1, utils.gen_handler(this.loop, this));
```
* 循环10次
TimerMgr.getInst().loopTimes(0.1, 10, utils.gen_handler(this.loopTimes, this));
- 延时0.2秒后再循环
- 0.2秒后再循环
TimerMgr.getInst().delayLoop(0.1, 0.2, utils.gen_handler(this.delayLoop, this));
- 延时0.2秒后招行一次
- 0.2秒后执行一次
TimerMgr.getInst().once(0.2, utils.gen_handler(this.once, this));
