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:0 yPos type:#float ui:ySpin default:0 zPos 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.x ySpin.value = $.pos.y zSpin.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
