1.只支持数字文字横向滚动，从开始数字到目标数字,间隔时长
2.使用时将脚本绑定在Label上调用 SetData 函数就可以了
代码如下:
import { _decorator, Component, Node, Label } from ‘cc’;
const { ccclass, property } = _decorator;
@ccclass(‘NumberScroll’)
export class NumberScroll extends Component {
isPlayAnim:Boolean = false;
start_num:number = 0; //开始数字
end_num:number = 0; //结束数字
src_number:number = 0;
add:number = 0; //总想加数量
temp_num = 0; //当前显示
callback = null; //回调
interval = 0.05; // 每隔50ms更新一次数值
dt = 0
stratTime = 0
endTime = 0
start() {
}
//将数字用逗号分隔
GetChangeNumber(num:number):string {
let formattedNum: string = new Intl.NumberFormat().format(num);
return formattedNum
}
//设置数字
SetData(end_num:number, start_num:number, duration: number, interval:number, callback: (value: number) => void){
if (null == interval){interval = this.interval}
this.interval = interval
this.start_num = start_num
const steps = duration / this.interval; // 计算需要更新多少次数值
this.add = (Math.abs(end_num - start_num)) / steps // 计算每步增加多少数值
this.temp_num = this.start_num // 当前数值初始化为起始数值
this.callback = callback
this.SetStringLabel(this.temp_num)
this.end_num = end_num
this.stratTime = new Date().getTime()
this.isPlayAnim = true
}
SetStringLabel(number){
let node = this.node.getComponent(Label);
node.string = this.GetChangeNumber(number)
}
SetStringLabelNull(){
let node = this.node.getComponent(Label);
node.string = ""
}
//定時器刷新
refreshTime(){
if(!this.isPlayAnim) return;
if(this.start_num > this.end_num){
this.temp_num -= this.add
}else{
this.temp_num += this.add
}
if (Math.abs(this.end_num - this.temp_num) <= Math.abs(this.add)) {
this.isPlayAnim = false
this.temp_num = this.end_num
if (this.callback){
this.callback(this.end_num)
}
this.endTime = new Date().getTime()
console.log("時常=",this.stratTime,this.endTime,(this.endTime - this.stratTime) / 1000)
}
this.SetStringLabel(this.temp_num)
}
update(deltaTime: number) {
if(!this.isPlayAnim) return;
this.dt += deltaTime
if (this.interval > this.dt) return;
this.dt = 0
this.refreshTime()
}
}
}
