autoKeyframe [-characterOption string] [-noReset] [-state boolean]

autoKeyframe is undoable, queryable, and editable.

With no flags, this command will set keyframes on all attributes that have been modified since an "autoKeyframe -state on" command was issued. To stop keeping track of modified attributes, use "autoKeyframe -state off"

autoKeyframe does not create new animation curves. An attribute must have already been keyframed (with the setKeyframe command) for autoKeyframe to add new keyframes for modified attributes.

You can also query the current state of autoKeyframing with "autoKeyframe -query -state".

Return value

intNumber of keyframes set.

In query mode, return type is based on queried flag.

MEL examples

// Start remembering attributes that have changed
autoKeyframe -state on;

// For all attributes that have changed since the
// last "autoKeyframe -state on", set a keyframe

// Stop remembering attributes that have changed.
// Note that Subsequent "autoKeyframe" commands
// (with no flags) will have no effect until an
// "autoKeyframe -state on" command is executed.
autoKeyframe -state off;

// When auto-keying, key all character attributes, not just
// those that have changed.
autoKeyframe -characterOption all;
