Description
Updated with an initial impulse filter.
A machine that looks very simple but needs a compex circuitry.
Get the cube and place it in front of the horizontal pusher. Press the button and the cube should travel it's round automatically. You see the vertical pusher moving up right in time, the funnel activating right in time and then deactivating when the cube touches the switch.
However the cube eventually doesn't cut the upper laser beam and the machine won't work correct.
In this case take the elevator to the maintenance room (2nd floor) and press the reset button.

Finally I got the time to add an initial impulse filter (see my map "How to fix the inverter glitch") and now the machinery works right from the start.

Well, another problem you may encounter if you add too much laser stuff into your map is that the laser will stop being transmitted after a certain limit ^^" Anyway you can use some combination of funnel/cube/button to replace the laser gates, but it's slower...

Thank you Geneosis. This map took me some days to complete. By looking at the notes I scanned and uploaded you can see it was a real brain blaster. :-D
And thank you for the valuable tips. I will try the angled plate and keep Hammer in mind.
P.S.: Such a huge logic circuit for two elevators and one funnel is insane. I didn't know before, it would become such a monster.

Oh and if you want to gain items, you can surround your objects with lights to hide some antlines (that cost a lot of items...). Or if you don't want, you can compile the map with Hammer to bypass the limit ^^

Well I think the explanation is the one you thought about : this laser emitter seems to start ON an have the time to activate the laser receptor before anything desactivate it when the map loads ^^ So I suggest adding a angled pannel in front of this emitter initially deployed and that retract when the player enter the room ^^

Anyway this map is a really advanced demo of how to use logic gates to make interesting things... Will add it in the Map Creator Tools collection too :p

Darn I can't add any more circuits because the compiler complains about too many objects. :-(

BTW the other laser is driven by the weighted cube switch at the opposite end of the tractor beam.

Great advice, narkfestmojo. *ThumbsUp*
I will try that.

Just played to find out the problem you are talking about.

You figured out you need an OR input to the 'reset' circuit (accomplished with two lasers into one floor catcher with one laser initiated with pedestal button) unfortunately I couldn't follow the other input to its source, way too many indicator strips. What you need is something that produces a lag and fires once into your OR gate.

This is easy, have a cube drop into a tractor beam and as it moves (slowly) along it's path, have it interrupt a laser to catcher. The catcher turns the other OR gate laser off so when it is interrupted it will give a single lasing pulse into your OR gate. This should give you a nice lag to reset your circuit and give you some 'insanity' prevention.

Hope this helps, but you should give Hammer a try, you're obviously smart enough and Hammer has stuff like logic_auto to help you fix default start problems. If I was doing this in Hammer I would just reset after OnMapSpawn.

Too few space for a detailed description. I hope you get the gist.
