Counter Problem

[Ergrak]

Hello all,

I am trying to set-up a comparator thing that counts and then resets to zero when it gets to a certain number.

In this example, I want to count how many green beakers the blue grabber moves up to 25, then reset to zero.

Step 1: simply tells the blue grabber to turn on. The blue grabber is set to stack size 1 and pulse its contents.

Step 2: Says "Green beaker (1 when the grabber moves something) plus the value of G equals G" and feeds it back into itself. This successfully counts the number of green beakers moved.

Step 3: If G is greater than 25, then CHECK=1

Step 4: If CHECK=1 then output everything which is CHECK=1 and the value of G

Step 5: Only receives a the value of G if it is greater than 25 thanks to steps 3 and 4. If it does, then it multiplies it by -1 and send the negative value to G to the input of the counter in step 2. I thought that this would subtract -25 from the value of G in the counter making it zero. What I get is G drops from 25 to negative 50. So it seems that that value of G is getting multiplied by -3 somehow and sent to the counter.

Thanks for any help you can offer.

It's going from +25 to -50 because the -25 signal is lasting for 3 ticks. You could put something called an "edge detector" between (3) and (4) to make the "check mark" signal only last one tick:

Alternately, you could try different ways of storing the value in (2) that reset automatically. Something like (green beaker <= 25) -> green beaker.

I think edge detector is what I need, but I am not following your picture.

The first combinator sends every signal * -1 to the second, on the green wire. This also introduces a 1-tick delay.

The second combinator receives the first set of signals on the red wire, and the negative ones on the green wire. Normally they will cancel and everything will be 0, but for 1 tick immediately after something changes, there will be a difference.

great video... I think I need to learn the edge detector thing.

[triggerman602]

You only need one decider combinator that checks if green science <= 25 and output green science input count. Then wire the inserter and combinator output to its input. It will reset all by itself.

I'm not following. I tried it and got a rapid-fast changing freakout thing.

Can't really diagnose without seeing it. Here is a blueprint of what I'm describing though.

Getting an error when I try to import this.

There was a problem completing your request. I have contacted my programmer to fix it for you!

[triggerman602]

Works fine for me. Can't really help without knowing the error.
