===== Code =====
<code xml>
<macro id="UserMacro.SetChaseOverlap50" name="Set Chase Overlap 50%">
  <description>Set fixture overlap of connected chase to 50%.</description>
  <sequence>
    <step>ActionScript.SetProperty("Playbacks.Editor.SelectedPlayback", Chases.ConnectedHandle)</step>
    <step>ActionScript.SetProperty.Float("Playbacks.Editor.Times.ChaseFixtureOverlap", 0.5)</step>
  </sequence>
</macro>
</code>

<code xml>
<!-- Ricster's reply: -->
<step>ActionScript.SetProperty("Playbacks.Editor.Times.ChaseFixtureOverlap", Math.Cast.ToSingle(1))</step>

<!--
     Might also work. 
     Or even 
-->

<step>ActionScript.SetProperty.Float("Playbacks.Editor.Times.ChaseFixtureOverlap", 1)</step>

<!-- And as of 10.1 I think you can do -->

<step>ActionScript.SetProperty("Playbacks.Editor.Times.ChaseFixtureOverlap", float:1)</step>
</code>
===== Explanation =====

This explains the functional steps within the sequence. For all the other XML details please refer to [[macros:formats_and_syntax#xml_format|Formats and syntax]]

  * ''ActionScript.SetProperty("Playbacks.Editor.SelectedPlayback", Chases.ConnectedHandle)'' makes the currently connected handle active in the editor
  * ''ActionScript.SetProperty.Float("Playbacks.Editor.Times.ChaseFixtureOverlap", 0.5)'' sets the property ''"Playbacks.Editor.Times.ChaseFixtureOverlap"'' to 0.5 which is 50%

Another example was published by kimwida: http://forum.avolites.com/viewtopic.php?f=20&t=5579 where the chasers are referred by their usernumber and a legend is set to reflect the current overlap value:

<code xml>
  <step pause="0.01">ActionScript.SetProperty("Playbacks.Editor.SelectedPlayback", handle:"chaseHandleUN=19159")</step>
  <step pause="0.01">ActionScript.SetProperty("Playbacks.Editor.Times.ChaseFixtureOverlap", 0.2)</step>
  <step pause="0.01">ActionScript.SetProperty("Playbacks.Editor.SelectedPlayback", handle:"chaseHandleUN=19160")</step>
  <step pause="0.01">ActionScript.SetProperty("Playbacks.Editor.Times.ChaseFixtureOverlap", 0.2)</step>
  <step pause="0.01">Handles.SetSourceHandleFromHandle("chaseHandleUN=1293")</step>
  <step pause="0.01">ActionScript.SetProperty("Handles.PendingLegend", "Overlap 20%")</step>
  <step pause="0.01">Handles.SetLegend()</step>
  <step pause="0.01">Handles.ClearSelection()</step>
</code>
===== How to use it =====

  - [[macros:deploying|make this macro available]]
  - once a chase is active and connected, fire this macro to set the chaser to 50% crossfade
