|
<h2 class="section">Saving your parameters</h2>
|
|
<div class="collapsable">
|
|
<div>
|
|
<p>The simplest way to save your parameters is via <code>GUI.saveURL()</code>. This method directs your browser to a URL containing the current GUI settings.</p>
|
|
<pre class="prettyprint">
|
|
// Make a button for the url function
|
|
gui.add(GUI, "saveURL");</pre>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
<div class="collapsed">
|
|
<h2 class="section">Advanced saving</h2>
|
|
<div class="collapsable">
|
|
<div>
|
|
<p>Let's say you'd like to share your settings with someone. Instead of sending a long link with lots of parameters stored in it, you can make your saved settings the defaults.</p>
|
|
|
|
<p>First, add the method <code>GUI.showSaveString()</code> to a gui object:</p>
|
|
<pre class="prettyprint">var gui = new GUI();
|
|
|
|
// Add some stuff (and pretend I change their values);
|
|
gui.add(someObject, "someProperty");
|
|
gui.add(someObject, "someOtherProperty");
|
|
|
|
// Make a save button.
|
|
gui.add(GUI, "showSaveString");</pre>
|
|
|
|
<p>Clicking the "showSaveString" button bring up an alert with a string. Copy and paste that string into the method <code>GUI.load()</code> before you instantiate any gui objects.</p>
|
|
<pre class="prettyprint">
|
|
// Replace COPIED STRING with the value you got from showSaveString()
|
|
GUI.load("COPIED STRING");
|
|
|
|
var gui = new GUI();
|
|
|
|
// Now these properties will be set to the values you just saved.
|
|
gui.add(someObject, "someProperty");
|
|
gui.add(someObject, "someOtherProperty");</pre>
|
|
|
|
<p><strong>Save strings won't work if you change the order in which you've added properties to your gui objects, or the order of the gui objects themselves.</strong>. If you want to add more parameters to your gui and use an old save string, make sure they're added after the properties whose values you've saved.</p>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
|
|
<div class="collapsed">
|
|
<h2 class="section">Listen for variable changes inside the GUI</h2>
|
|
<div class="collapsable">
|
|
<div>
|
|
<p>To fire a function whenever a user changes a variable via the GUI, use the following syntax:</p>
|
|
<pre class="prettyprint">gui.add(obj, "propertyName").onChange(function(newValue) {
|
|
alert("You changed me to " + newValue);
|
|
});</pre> <p>This can be slightly annoying for types like number or string. You may not want to fire a function while the user is sliding, or while they're typing. To fire a function when the user has <em>finished</em> making changes, use the following:</p>
|
|
<pre class="prettyprint">gui.add(obj, "propertyName").onFinishChange(function(newValue) {
|
|
alert("You just finished changing me to " + newValue);
|
|
});</pre>
|
|
<p>Finally, if you'd like to do a little something extra when a function is called, use the following:</p>
|
|
<pre class="prettyprint">gui.add(obj, "functionName").onFire(function() {
|
|
alert("You called a function with gui-dat");
|
|
});</pre>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
<div class="collapsed">
|
|
<h2 class="section">Listen for variable changes outside of the GUI</h2>
|
|
<div class="collapsable">
|
|
<div>
|
|
<p>Let's say you have a variable that changes by itself from time to time. If you'd like the GUI to reflect those changes, use the <code>listen()</code> method.</p>
|
|
<pre class="prettyprint">gui.add(obj, "changingProperty").listen();</pre>
|
|
</div>
|
|
</div>
|
|
</div>
|

|
<div class="collapsed">
|
|
<h2 class="section">Advanced listening</h2>
|
|
<div class="collapsable">
|
|
<div>
|
|
<p>By default, <strong>gui-dat</strong> will create an internal interval that checks for changes in the values you've marked with <code>listen()</code>. If you'd like to check for these changes in an interval of your own definition, use the following:</p>
|
|
<pre class="prettyprint">
|
|
gui.autoListen = false; // disables internal interval
|
|
gui.add(obj, "changingProperty").listen();
|
|
|
|
// Make your own loop
|
|
setInterval(function() {
|
|
gui.listen(); // updates values you've marked with listen()
|
|
}, 1000 / 60);</pre>
|
|
|
|
<p>Alternatively, you can forego calling <code>listen()</code> on individual controllers, and instead choose to monitor changes in <em>all</em> values controlled by your gui.</p>
|
|
<pre class="prettyprint">
|
|
gui.autoListen = false; // disables internal interval
|
|
gui.add(obj, "add");
|
|
gui.add(obj, "lotsa");
|
|
gui.add(obj, "properties");
|
|
|
|
// Make your own loop
|
|
setInterval(function() {
|
|
gui.listenAll(); // updates ALL values managed by this gui
|
|
}, 1000 / 60);</pre>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
|
|
<div class="collapsed">
|
|
<h2 class="section">Multiple panels and custom placement</h2>
|
|
<div class="collapsable">
|
|
<div>
|
|
<p>You can instantiate multiple <code>GUI</code> objects and name them however you'd like.</p>
|
|
<pre class="prettyprint">var gui1 = new GUI();

var gui2 = new GUI();

// The name function overwrites the "Show Controls" text.
|
|
gui1.name("Utilities");
|

gui2.name("Camera Placement");</pre>
|
|
|
|
<p>By default, <strong>gui-dat</strong> panels will be automatically added to the HTML document and fixed to the top of the screen. You can disable this behavior / styling and append the gui DOM element to a container of your choosing.</p>
