Designed for 2d objects, such as a canvas placements, this permits the receipt of touch (mouse click) events to enable the simulation of avionics with a touchscreen.
The coordinates are passed in as arguments to the action; these can be accessed with Nasal via the cmdarg() method.
example:
<animation>
<type>touch</type>
<visible>true</visible>
<object-name>VSDImage</object-name>
<action>
<touch>0</touch>
<repeatable>false</repeatable>
<binding>
<command>nasal</command>
<script>print("touch input
(",cmdarg().getNode("x").getValue(),",",cmdarg().getNode("y").getValue())</script>
</binding>
</action>
</animation>
