Frame List Stimulus

Description

A simple movie stimulus that presents its frames at the native refresh rate of the display. The frames can be provided by a stimulus group or attached directly to the frame list as child components.

Signature

stimulus/frame_list

Optional Parameters

stimulus_group

Stimulus group providing the frames

ending

Variable that will be set to true when the frame list begins drawing its last frame (thereby notifying you of the optimal time to queue stimuli that should be displayed during the frame immediately following said last frame)

ended

Variable that will be set to true after the last frame has displayed. (Specifically, it will be set to true at the time that the next frame after the last would have been drawn, if there were one.)

loop

Default

NO

If YES, the presentation will repeat indefinitely (or until Stop Dynamic Stimulus is invoked)

repeats

Default

0

Number of times to repeat the presentation. Note that the presentation will always run at least once, even if this value is less than one.

If loop is YES, this parameter is ignored.

deferred

Options
no
yes
explicit
Default

no

Controls when the stimulus is loaded. If no, the stimulus is loaded at experiment load time. If yes, the stimulus is loaded the first time it is queued. If explicit, the stimulus must be loaded explictly with Load Stimulus.

autoplay

Default

NO

If YES, the stimulus will start playing automatically (as if by an implicit Play Dynamic Stimulus action) after it has been queued and Update Stimulus Display has been invoked. It will also stop playing automatically (as if by an implicit Stop Dynamic Stimulus action) after it has been dequeued and Update Stimulus Display is invoked.
