为对象增加属性2

给增加的属性添加事件

说明：点击“获取坐标”按钮，在spinner中列出所选对象的X ， Y ，Z 坐标

改变spinner的值，可以改变所选对象的坐标

 

列出代码：

newAttrib = attributes posAttribs(parameters PosParam rollout:optRoll(xPos type:#float ui:xSpin default:0yPos type:#float ui:ySpin default:0zPos type:#float ui:zSpin default:0)rollout optRoll "Options...."(spinner xSpin "X Position" type:#float range:[-300,300,0]spinner ySpin "Y Position" type:#float range:[-300,300,0]spinner zSpin "Z Position" type:#float range:[-300,300,0]button bt1 "获取坐标"on bt1 pressed do(xSpin.value = $.pos.xySpin.value = $.pos.yzSpin.value = $.pos.z)on xSpin changed tempV do($.pos.x = xSpin.value)on ySpin changed tempV do ($.pos.y = ySpin.value)on zSpin changed tempV do($.pos.z = zSpin.value)))custAttributes.add $ newAttrib
