Hy there,
I got a very simple setup, but already odd behavior when using two keys. At least I interpret it like that.
To the code below and its outcome I have the following questions:
- Why is it such a big difference in speed when using either Commands or KeyTriggers. -> somehow related to the last post…
- Why does a Command action interrupt a KeyTrigger action ? And why does it work fine the other way around ?
- Here too, is there something I should know about not mixing these two kind of triggers, or do I just use them wrong ?
I am using the latest SVN Revision 4483 from http://jmonkeyengine.googlecode.com/svn/trunk/
Thank you for any answers,

* maxx_981, TestInputHandlerTwoButtons
*
* Tested on:
* - Intel Core Duo E8200, 32-bit Vista
* - Genuine Intel CPU T2500, 32-bit XP
* -> same behavior
* <p/>
* Don't think the graphics setup is of any importance here ...
* <p/>
* Strange behavior with just two actions defined.
* The target of the test is, to have a key with repeating trigger and evt information about triggerPressed,
* and to have another key, which does not need the triggerPeessed information and is also repeating.
* <p/>
* So the setup below is my try to achieve this ;-) which fails terribly ....
* <p/>
* If you press button 1 you will notice how slow the updates are, and there are some initial hangers.
* But it is repeating the action even though it's set to false; -> related to my last post
* <p/>
* If you press button 2 additionally, certainly button 1 stops getting updates, also after releasing the button 2 again.
* <p/>
* So this scenario outpus:
* ...
* Performing Key-Trigger-Action Key1
* Performing Key-Trigger-Action Key1
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* ...
* <p/>
* If you first press button 2 and then button 1, you see a behavior I would call correct, as both are repeating its
* actions. But the Key-Trigger-Action is so much slower ... this looks like:
* <p/>
* ...
* Performing Comman-Action Key 2
* Performing Key-Trigger-Action Key1
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* Performing Comman-Action Key 2
* Performing Key-Trigger-Action Key1
* Performing Comman-Action Key 2
* ...
