Moving Lasers

(PART 3)

The "off" button can be connected to an angle panel which lifts up and blocks the laser. Alternatively, the way I have it set up in this map is to point a laser at a catcher, connect the catcher to the second laser (the one that's powering itself), and make it so the new laser is turned off by the "off" button. So when we press that button, the catcher no longer has a laser pointing at it and that makes the second laser stop powering itself. You can see all this happening under the glass in the floor of the first room.

Once you have that figured out, just replace the buttons in the example with the laser catchers you see on the wall of the first room. One of those is the "on" input for the SR latch, the other one is the "off" input.

The design for an SR latch is pretty simple. In our funnel example, first we want to figure out how to keep the funnel reversed after letting go of the "on" button. To do that, we need two lasers both pointed at a single relay. The button turns on one of the lasers, which then hits the relay. We set it up so the relay turns on the other laser, which is itself pointed at the relay! This means that after you release the button, the second laser will continue to power itself by pointing at the relay. We just have to hook up the relay to the funnel, and that makes it so that the funnel stays reversed even after you let go!

After that, we just need to make it so the second button resets the funnel. Since the second laser is powering itself, if we block it even for a split second, the relay loses power and the laser turns off (until we hit the "on" button). We can achieve this in a couple of ways. The "off" button can be connected to an angle panel which lifts up and blocks the laser.

Sure! So it's not too complicated. All you really need to know is what an SR latch is.

I ended up writing quite a bit here, but I promise it's not complicated, I just got a little detailed with my explanation. I have a map (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=85980963) that showcases some simple SR latch demos (rooms 2 and 3 I think), and if you have any other questions I'd be glad to answer them.

(PART 1)

So let's say I want a funnel to be start out flowing normally, but I have a button that reverses its flow. That's simple enough to do, just connect the button to the funnel. But what if I want the flow to stay reversed even after I step off the button? And I want to have a second button that I can step on to set the flow back to normal? That's a little more complicated to do, and that's what an SR latch is for, it lets us have one input that turns something on, and another input that turns that thing off.

Can you make a comment, that explains this for begginners, like me? I have no idea what any of this means

@blu tiger135 If you look at the wall across from the laser, there are two laser catchers. There are connected to an SR latch, which is a device that turns things on and off. The SR latch is connected to the excursion funnel's polarity. You can check SR latches out in my map "HOLD Gates, SR Latches, and Priority Switches"

how do u make the lasers move back and forth.
how do you make the excursion funnel reverse polarity like that ?

MAJOR UPDATE: I've merged my "Moving Laser Demonstration" map into this one. This required me to simplify the first room a little bit. I'm on the very edge of the item limit, so I can't really add anything.

Thanks for adding it :) It would definitely be interesting to combine this with angled panels, but then the player could probably mess around with it :/ I don't usually design test chambers though, only mechanisms, so it could be a while before I incorporate this into a puzzle.

Wow, this is a really cool mechanism you have there ^^ Will add it to the Map Creator Tools collection ;)
Well if you want you could have angled lasers in your funnel, or make them move with 30/45/60 deg angle if the player transmit the funnel to an angled pannel ;)
And this remind me my map Feel the Magic :p This is more about flying lasers, but they also move a moment ;)
