moving portal mechanic?

You guys probably remember this puzzle from the main game that used this mechanic. So you got a 3X3 square room with a pit in the middle and 2 portals on opposite ends rotating around the room counter clockwise. There are some other elements about the room but that's irrelevant according to what I need to accomplish in my own version of the puzzle. How would I implement this portal rotation? I thought I had a way by putting portals on all squares inside the room and using timers, but the way I had it in my head got too confusing and used too many timers. Any ideas on what to use, be it timers, counters or script? I am definitely interested in multiple way to do it too. Here is a slide show illustration of what I mean if anyone is unable to understand my description. The portals should change every 1 second in a continuous rotation around the room. I want it to be triggered with a hidden pressure plate when entering the room and stopped by another pressure plate on the other end.

Hint: there are four states, so you need a ticker that goes 0,1,2,3,0,1,2,3,...

an easy way to code it - not elegant but fairly straight forward, would be to use a single timer connected to a lua script with a setting of 1
the script would have a function
Code: Select all
step = 1
function cycleTeleports()
if step==1 then
telport1:activate()
telport4:deactivate()
telport5:activate()
telport8:deactivate()
step = 2
else if step==2 then
telport1:deactivate()
telport2:activate()
telport5:deactivate()
telport6:activate()
step = 3
else if step==3 then
telport2:deactivate()
telport3:activate()
telport6:deactivate()
telport7:activate()
step = 4
else
telport3:deactivate()
telport4:activate()
telport7:deactivate()
telport8:activate()
step = 1
end
All we are really doing is building a counter into the script and then turning off two and turning on two each tick of the timer.
The pressure pads would activate and deacivate the timer - you would also have them deactivate all the teleports
Code: Select all
function resetTeleports()
telport1:deactivate()
telport2:deactivate()
telport3:deactivate()
telport4:deactivate()
telport5:deactivate()
telport6:deactivate()
telport7:deactivate()
telport8:deactivate()
step = 1
end
this would need to be in the same script entity as the first script.
Am unable to test this, but it should work - if the second script cant see step, then link it to a counter instead

I tested this and it worked well, although I needed to fix a couple of minor mistakes in the script (easily done when writing untested code). I also changed the names of the teleporters in the script to the convention used by the editor when placing them.
Code: Select all
step = 1
function cycleTeleports()
if step==1 then
teleporter_1:activate()
teleporter_4:deactivate()
teleporter_5:activate()
teleporter_8:deactivate()
step = 2
elseif step==2 then
teleporter_1:deactivate()
teleporter_2:activate()
teleporter_5:deactivate()
teleporter_6:activate()
step = 3
elseif step==3 then
teleporter_2:deactivate()
teleporter_3:activate()
teleporter_6:deactivate()
teleporter_7:activate()
step = 4
elseif step==4 then
teleporter_3:deactivate()
teleporter_4:activate()
teleporter_7:deactivate()
teleporter_8:activate()
step = 1
end
end
function resetTeleports()
teleporter_1:deactivate()
teleporter_2:deactivate()
teleporter_3:deactivate()
teleporter_4:deactivate()
teleporter_5:deactivate()
teleporter_6:deactivate()
teleporter_7:deactivate()
teleporter_8:deactivate()
step = 1
end
In addition to the script you will need
- a timer with interval 1 second and with action point at the script entity cycleTeleports
- start pressure plate with 2 CONNECTORS
---- one to the script entity resetTeleporters
---- one to the timer with an activate action
- end pressure plate
with 2 CONNECTORS
---- one to the script entity resetTeleporters
---- one to the timer with an deactivate action

Yeah, it's threads like this that really peel back the curtain
and this would probably make a decent addition to the
Useful scripts repository

Thanks for all the advice guys. I managed to get this to work. I was also able to adapt it to some other puzzles I made. This dungeon is coming along nicely!

I think it's just a typo. "Can we play with this?"
