I am trying to use TiddlyWiki to create a database of exercises. The
database includes descriptions on how to prepare for and execute an
exercise, with corresponding videos for the preparation and execution
movements.
My current intention is for each exercise tiddler to open with a thumbnail
image of the exercise along with two buttons that will allow the user to
view either the preparation or execution videos. In each case, the
thumbnail image (or video) should be replaced with the preparation or
execution video of the respective button when selected.
I have created the tiddler template below to include the videos in each
exercise tiddler, and it pretty much does what I want, except for one
problem, which I don't know how to solve.
What I would like to happen is that when the exercise tiddler is closed and
reopened, the tiddler returns to the original state of showing the
thumbnail image. However, as I need to use a field or tiddler to store the
button/reveal state, when I reopen an exercise tiddler it uses the last
state value that was set.
Is there a way to use variables for this purpose or to reset a tiddler
field when a tiddler is closed? Alternatively, is there a better way to
solving my problem?
<$button><$action-setfield $tiddler="$:/exw/state/video"
$value="prep"/>Preparation</$button>
<$button><$action-setfield $tiddler="$:/exw/state/video"
$value="exec"/>Execution</$button>
<$reveal type="nomatch" state="$:/exw/state/video" text="image">
<$button><$action-setfield $tiddler="$:/exw/state/video"
$value="image"/>Reset</$button>
</$reveal>
<$reveal type="match" state="$:/exw/state/video" text="prep">
<video width={{$:/exw/setting/video-size}} autoplay src=
{{!!video-preparation}}/>
</$reveal>
<$reveal type="match" state="$:/exw/state/video" text="exec">
<video width={{$:/exw/setting/video-size}} autoplay loop src=
{{!!video-execution}}/>
</$reveal>
<$reveal type="match" state="$:/exw/state/video" text="image">
<$image width={{$:/exw/setting/video-size}} source={{!!image}}>
</$reveal>
