Am thinking that similar wording should be provided for IntegerTrigger integerKey field, e.g.<br>
<br>
"Resetting the /integerKey/ field generates a<br>
corresponding /integerKey/ field output event."<br>
<br>
<a href="http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/utils.html#IntegerTrigger" rel="noreferrer" target="_blank">http://www.web3d.org/documents<wbr>/specifications/19775-1/V3.3/P<wbr>art01/components/utils.html#In<wbr>tegerTrigger</a><br>

==============================<wbr>================<br>
30.4.6 IntegerTrigger<br>
<br>
IntegerTrigger : X3DTriggerNode {<br>
SFBool [in] set_boolean<br>
SFInt32 [in,out] integerKey -1 (-∞,∞)<br>
SFNode [in,out] metadata NULL [X3DMetadataObject]<br>
SFInt32 [out] triggerValue<br>
}<br>
<br>
IntegerTrigger handles single field Boolean events to set an integer value for the output event. This is useful for connecting environmental events to the Switch node's whichChoice field.<br>
<br>
Upon receiving a set_boolean event, the IntegerTrigger node will generate a triggerValue event with the current value of integerKey. The value of set_boolean shall be ignored.<br>

Sending output fields upon value changes is how the browsers I tested behaved. Although to me the sentence in 4.4.8.1 which addresses this behaviour and begins with "Nodes also define output fields .." is more explanatory than defining and seems to be intended to leave the exact behavior specification to node definitions. Here is suggested wording to help clarify 30.4.3:<br>
<br>
The BooleanToggle can be reset to a specific state by directly setting the value of the inputOutput /toggle/ field. Resetting the /toggle/ field generates a corresponding /toggle/ field output event.<br>
<br>
There is probably a better and/or more concise phrase to add.<br>

Thank you Andreas. Looks like you have identified an ambiguity in the spec<br>
that might benefit from clarification.<br>
<br>
Since the first paragraph specifically identified output events, and the<br>
second paragraph on "reset" did not, my interpretation was that no event was<br>
sent as part of a reset. That informed the tooltips and diagram notes. However, checking event model rules:<br>
<a href="http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/concepts.html#Events" rel="noreferrer" target="_blank">http://www.web3d.org/documents<wbr>/specifications/19775-1/V3.3/P<wbr>art01/concepts.html#Events</a><br>

4.4.8 Event model<br>
<br>
<br>
4.4.8.1 Events<br>
<br>
/Events/ are the primary means of generating behaviors in the X3D run-time<br>
environment. Events are used throughout X3D: driving time-based<br>
animations; handling object picking; detecting user movement and<br>
collision; changing the scene graph hierarchy. The run-time environment<br>
manages the propagation of events through the system according to a<br>
well-defined set of rules.<br>
<br>
Nodes define input fields (/i.e./, fields with inputOutput or inputOnly<br>
access) that trigger behavior. When a given event occurs, the node<br>
receives notification and can potentially change internal state and the<br>
value of one or more of its fields. *Nodes also define output fields<br>
(/i.e./, fields with inputOutput or outputOnly access) that are sent upon<br>
signal state changes or other occurrences within the node.* Events sent to<br>
input fields and events sent by output fields are referred to collectively<br>
in ISO/IEC 19775 as /Events/.<br>
<br>
</blockquote>
<br>
The bolded sentence (beginning with "Nodes also define output fields... that<br>
are sent upon signal state changes" ...) indicates that a corresponding<br>
output event should be sent when the value is changed.<br>
<br>
Subject to review, am happy to make the tooltips and diagram notes more<br>
explicit in this matter. We should likely also add words to spec to avoid<br>
indirect ambiguity and explicitly add clarity.<br>
<br>
all the best, Don<br>
