属性详细信息

distanceLimit

属性
distanceLimit:Number

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

IK 引擎应该对每次迭代移动的最大距离(以像素为单位)。该距离按欧几里德距离进行计算:

sqrt(dx*dx + dy*dy)



实现
    public function get distanceLimit():Number
    public function set distanceLimit(value:Number):void

相关 API 元素

iterationLimit

属性 
iterationLimit:int

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

指定 IK 引擎对每个运动执行的最大迭代次数。必须将 limitByIteration 属性设置为 true 才能使用 iterationLimit 值。如果 limitByIteration 属性为 true,IK 引擎将遍历指定次数的迭代,或直至 IKJoint 对象到达目标点。如果此类的所有“limitBy...”属性都为 false,IK 引擎将执行一个步骤。如果任意“limitBy”属性为 true,IK 引擎将继续处理,直到达到条件限制或目标中存在结束效果器为止。



实现
    public function get iterationLimit():int
    public function set iterationLimit(value:int):void

相关 API 元素

limitByDistance

属性 
limitByDistance:Boolean

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

指定在超过 distanceLimit 值后 IK 引擎是否结束运动。



实现
    public function get limitByDistance():Boolean
    public function set limitByDistance(value:Boolean):void

相关 API 元素

limitByIteration

属性 
limitByIteration:Boolean

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

指定在超过 iterationLimit 值后 IK 引擎是否结束运动。



实现
    public function get limitByIteration():Boolean
    public function set limitByIteration(value:Boolean):void

相关 API 元素

limitByTime

属性 
limitByTime:Boolean

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

指定在超过指定的 timeLimit 后 IK 引擎是否结束运动。



实现
    public function get limitByTime():Boolean
    public function set limitByTime(value:Boolean):void

相关 API 元素

stepCount

属性 
stepCount:int  [只读]

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

IK 运动的迭代次数。



实现
    public function get stepCount():int

timeLimit

属性 
timeLimit:int

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

指定 IK 引擎执行运动的最长时间(以毫秒为单位)。必须将 limitByTime 属性设置为 true 才能使用 timeLimit 值。如果 limitByTime 属性为 true,IK 引擎将运行指定的毫秒数,或运行到 IKJoint 对象到达目标点为止。如果此类的所有“limitBy...”属性都为 false,IK 引擎将执行一个步骤。如果任意“limitBy”属性为 true,IK 引擎将继续处理,直到达到条件限制或目标中存在结束效果器为止。



实现
    public function get timeLimit():int
    public function set timeLimit(value:int):void

构造函数详细信息

IKMover

()构造函数
public function IKMover(endEffector:IKJoint, targetIn:Point)

语言版本: ActionScript 3.0
产品版本: Flash CS4
运行时版本: Flash Player 10, AIR 1.5

IKMover 对象的构造函数。对于形状 IKArmature 对象,构造函数将忽略 targetIn 点参数。

参数
endEffector:IKJoint — 要移动的 IKJoint 对象。
 
targetIn:Point — 运动的起点坐标。此点类似于 Flash 创建工具的舞台上的点,您可以单击作为 IKArmature 对象的一部分(不一定是连接)的元件,移动该元件,从而按照为 IKArmature 对象规定的限制移动 IKArmature 对象。

例如,您有腿和脚,并想要从脚趾开始移动脚。如果您在脚的脚趾处指定一个 targetIn 点,则可以从该点开始移动脚。否则,您必须在脚趾处创建一个元件,将脚趾与骨骼连接,这样才能移动脚。

[ X ]为什么显示为英语?
《ActionScript 3.0 参考》中的内容以英语显示

《ActionScript 3.0 参考》中的部分内容未翻译成所有语言。当某个语言元素未翻译时,将显示为英语。例如,ga.controls.HelpBox 类未翻译成任何语言。因此在简体中文版的参考中,ga.controls.HelpBox 类显示为英语。
