In/Out platform movement?

Archive: 9 posts


I was wondering how you get plats to move from back plane to front and back again. I know it involves a mover I think, but I need to get it to function as though the block were on a piston pushing in sync from one plane to another and back.

My plan is to have a block ledge climb that starts from below and moves up in sequence then starts over much like syncing pistons for a wave, and only 2 blocks will be out at any 1 time so that when the next block in the climb comes out, the last one retracts. So block B and C are out, then when D comes out B retracts and so on. It continues in that fashion, so player has to hurry up climbing using the 2 blocks out at any one time. None of this will be activated by player. I want it to be a constantly active cycle so I would think any special sensors arent needed.

Set up your platforms with a microchip with a battery, a NOT gate, and two in-out movers one that moves in one that moves out. Connect the battery output to one in-out mover, and the NOT gate. Connect the output of the NOT gate to the other in-out mover.

Now place as many blocks as you want, and set up a selector with the same number of ports as you have blocks. Connect the output of each selector port to the bottom of 1 of the blocks microchips (preferably in sequential order). You can set a timer gadget to count up, and connect the output of the timer to its own reset and to the cycle input of the selector. Each time the timer fills, another box will move out and the others will move in.

Wow! All of that just hurt my brain. >>

Thank you. I'll try following that step by step and see where I end up.

I'll still be checking this thread though in case anyone knows of an easier way. If I get the above method working I'll post or edit that I did.

Read through rtm223's logic blog. It will shed some light on many of the elements I described.2011-01-21 04:10:00

Okay, I tried everything you mentioned. It was very easy to set up. Confusing at first then I got it.

But it isn't working, the blocks will go in one by one rather than 2 out at a time, and when the cycle repeats (I know repeat is working because you can see the wires turn yellow from beginning again) the blocks wont come out as though they can only move in and that's it.

No matter what setting I set the movers for with one mover to in or back and out or front, nothing gets them to move out and then in.

Maybe do what you did, but twice, so one timey-wimey thing for A and C, and one for B and D.

Then switch around the NOT gate and battery on B and D.

Sorry if I've said this cryptically, but ideally one timey-selector thing will be doing the opposite to the other.

Here's how i would start with it.

On each block have two movers. Set one so that when it is activated it moves to the back position, and the other so that when it is activated it goes to the forward. Basically that gives you an on/off pair.

Place a NOT gate next to your off position mover and connect the output from that to your off mover.


Next place a selector with as many outputs as you have blocks. and attach the cycle input to a battery. The selector will continually cycle through each output, and repeat when it finishes. Connect each output from the selector to both the on mover, and the not gate on each block.

I know you said you wanted two out at a time, but this is all i can think of off hand. It should give you at least a good basic start.

Just do this and wire the first selector to two blocks and the second to the other two.

Hey guys thanks for all the help!

A friend helped me last night and took it to his moon and figured it out in 8 minutes. This happened before tdarb's post.

In order to have only 2 blocks out at any one time with the 3rd coming out and the first retracting so on until cycle ends and repeats, he did this . . .

The first and last block of the 6 had a different logic set on the chips.

Block 1: OR gate, NOT gate, and 2 in/out movers with one for in and one for out
Block 2 through 5: NOT gate, and 2 in/out movers with one for in and one for out
Block 6: OR gate, NOT gate, and 2 in/out movers with one for in and one for out

Instead of a selector, he said if I wanted more than 1 block out at once rather than one at a time I would need a sequencer instead of a selector.
So he wired each port of the sequencer set to as many blocks as I have to each logic pieces on chips. So for block 5 and 6 he had to wire the OR gate twice from that blocks port, then wired the OR gate to one mover and the NOT gate, then wire the NOT gate to the other mover. And for 2 through 5 he wired the NOT gate and one mover from same port, and the NOT gate to the other mover.

He also said sometimes the game acts weird and wont function right if you wire to the chip itself rather than pieces on the chip.

Then finally he wired a battery to the sequencer. To start the sequence block 1 and 6 (1st and last) had to begin already out while 2 through 5 start in the in position.

I just shared this to spread LBP2 knowledge around. Hope I didn't make it sound too confusing.
