IKJoint  - AS3 Flash

The head bone associated with the IKJoint object.

Static constant for the rotation degree of freedom.

Static constant for the x-translation degree of freedom.

Static constant for the y-translation degree of freedom.

The IKJoint instance's name.

Returns the number of IKJoint objects branching from the specified IKJoint. This method does not account for sub-branches. Traverse each child branch to traverse the whole IKArmature object.

The parent IKJoint object.

The IKJoint's coordinates.

The current rotation value. This value is read-only. The IKMover object udpates this value automatically during an IK movement.

Returns if the rotation is constrained.

Specifies if the rotation is enabled.

The maximum rotation value.

The minimum rotation value.

The rotation speed degree of freedom; the xTranslation and yTranslation properties respect the same speed setting.

The spring damping value. Damping adds spring resistance when used in conjunction with the strength property. It affects the rate of decay for the spring, which is the amount of time between the initial movement and when the bones connected to the joint return to their rest position. The range is from 0 (no resistance, the default) to 100 (highly damped). A maximum damping value does not negate strength With damping at 100 and strength at 1, there is still an effect. Because of the rigidity of the joint, it may be difficult to notice, but there is a physics-based reaction nonetheless.

import fl.ik.*;

var armature:IKArmature = IKManager.getArmatureAt(0);
armature.springsEnabled = true;
var joint:IKJoint = armature.rootJoint;
while(joint)
{
    joint.springStrength = Math.random() * 10;
    joint.springDamping = Math.random() * 100;
    
    if(joint.numChildren > 0)joint = joint.getChildAt(0);
    else joint = null;
}

The spring position (for translational joints) or angle (for rotational joints).

The spring strength value. This is the amount of spring in the joint. The range is from 1-100, with 0 being rigid (the default Flash behavior) and 100 being a very loose spring that is mostly controlled by physics.

var armature:IKArmature = IKManager.getArmatureAt(0);

var joint:IKJoint = armature.rootJoint;

    if(joint.numChildren > 0)joint = joint.getChildAt(0);
    else joint = null;
}

The current x-translation value. This value is read-only. The IKMover object udpates this value automatically during an IK movement.

Returns if the x-translation is constrained.

Specifies if the x-translation is enabled.

The maximum x-translation value.

The minimum x-translation value.

The current y-translation value. This value is read-only. The IKMover object udpates this value automatically during an IK movement.

Returns if the y-translation is constrained.

Specifies if the y-translation is enabled.

The maximum y-translation value.

The minimum y-translation value.

Clears the current spring angle.

Clears the current spring point.

Returns the child IKJoint object at the specified index value.
