3. Already done

Just two step, and add new barrage message by pushing data into the barrageList. You needn't concern about the management of the barrageList, it will be handled by vue-baberrage. Suggest the barrageList store into the Vuex.

Custom Example

New function in version 3.2.0. Support provides VNode to render the barrage.

<vue-baberrage
        ref="baberrage"
        :lanesCount="5"
        :boxHeight= "stageHeight"
        :isShow= "barrageIsShow"
        :barrageList = "barrageList"
        :loop = "barrageLoop"
        :maxWordCount = "60"
        :hoverLanePause = "hoverLanePause"
        >
		<template v-slot:default="slotProps">
			<span style="color: #000">
			{{slotProps.item.data.userName}}: {{slotProps.item.msg}}
			</span>
		</template>
	  </vue-baberrage>

Customized your barrage UI as the slot of component.props.item data same as barrage data. Noticed that, if the width of barrage not fit in stage. You can add the field extraWidth in barrage data.

{
	id: ++this.currentId,
	avatar: "./static/avatar.jpg",
	msg: this.msg,
	data: {
	  userName: 'more data'
	},
	time: 5,
	type: MESSAGE_TYPE.NORMAL,
	extraWidth: 60
}

Since vue-baberrage only count the width of length of the barrage's message.
