Your OPE has a hit trigger going to a state event.

Spawn an Impulse splitter and make the hit trigger go to the impulse splitter. Set the impulse splitter to go to the state event.

Spawn your sound effect and sound event. Set the impulse splitter to target that and away you go. If its still not aligned correctly, try inserting an impulse delay between the impulse splitter and the sound event (or the OPE) and this will enable you to try and sync them by delaying the start of one of them.

Then spawn another sound event and effect and another impulse delay. Set these to trigger at the end of the ope movement (you have a time period set for your OPE so use that as the delay for the impulse delay). Then set the impulse trigger to target the impulse delay. This should now be triggered when the OPE is, but the impulse delay will prevent the signal reaching your "bang" until the end of the OPE cycle.

So it will be trigger > splitter > impulse delay > event > etc.

Each splitter can accomodate 8 targets, fyi.

Hope that makes sense. If not, check this page: <!-- l --><a class="postlink-local" href="http://www.redlynxgame.com/forum/viewtopic.php?f=83&t=10376">viewtopic.php?f=83&t=1 0376</a><!-- l -->

which links to tutorials by the community including my little one for impulse splitters! lol
