效果

原理与源码

获取角度，然后一直更改角度，角度到达180度后赋值成-180度，然后转到开始获取的角度的角度的时候就停止旋转

            function rotateModel(layerID){let bearing = map.getPaintProperty(layerID,"model-rotation")let afterBearing = [0,0,bearing[2]+1]let interval =setInterval(()=>{if(afterBearing[2] ==bearing[2]){clearInterval(interval)}else{if(afterBearing[2]==180){afterBearing[2] = -180map.setPaintProperty(layerID,"model-rotation",afterBearing,)}else{afterBearing=[0,0,afterBearing[2]+1]map.setPaintProperty(layerID,"model-rotation",afterBearing,)}}},0)}
