interface()

Syntax

xtra("XtraName").interface()

interface(xtra "XtraName")

Description

Function; returns a Return-delimited string that describes the Xtra and lists its methods. This

function replaces the now obsolete mMessageList function.

Example

This statement displays the output from the function used in the QuickTime Asset Xtra in the

Message window:

put Xtra("QuickTimeSupport").interface()

interpolate()

Syntax

transform1.interpolate(transform2,percentage)

Description

3D transform method; returns a copy of transform1 created by interpolating from the position

and rotation of

transform1 to the position and rotation of transform2 by the specified percentage.

The original

transform1 is not affected. To interpolate transform1, use interpolateTo().

To interpolate by hand, multiply the difference of two numbers by the percentage. For example,

interpolation from 4 to 8 by 50 percent yields 6.

Example

In this example, tBox is the transform of the model named Box, and tSphere is the transform of

the model named Sphere. The third line of the example interpolates a copy of the transform of

Box halfway to the transform of Sphere.

tBox = member("3d world").model("Box").transform

tSphere = member("3d world").model("Sphere").transform

tNew = tBox.interpolate(tSphere, 50)
