Hello.

Is there a way (in Dispatcher) to compare 2 counters, and if the difference between them is a certain value, do the action? I cannot figure it out  

I use counters a lot, and love them   but I haven't found how to do just this   Is it possible?

Best regards,
Per

Hi Per,

sure, you can do that. Within the dispatcher you'll find the condition "counter comparism" (expertmode is mandatory). Here you are able to set the conditions between two counters (e.g. not-equal). The corresponding action in your case could be "counter calculation".

Hello!

Thank you.  I already know this.  This works if the 2 counters are equal, or if one is bigger (smaller) than the other.  But I want this to be true ONLY if the difference between the two, are for example 4.  Can I do that?

Per.

Hello Per,

I don't have WDP open right now but I would use a third counter. This counter is always the second counter minus 4. Now you can compare the first and the third counter.

Hello, Stefan!

Yes, I was thinking something like that myself.  But I was hoping there was an easier way

Stefan, can you show me an example?  I am actually struggling with this..

Hi again.

My problem is:  How do I make "Counter 2" always 4 (or any other value) higher (or lower) "Counter 1" ?  To be true always when "Counter 1" changes value.

Per.

Hi Per,


I'm a little short of time at the moment. But I will think about your problem.

Hi Per,

I found the solution yesterday when lying in my bed. The point is that a dispatcher fires only if a condition becomes true. It does not fire if it is already true. Counter 1 is your starting point and counter 2 should be counter 1 plus 4. So you need a condition that changes when you change counter 1.

You need 4 counters. There are the above mentioned counters 1 and 2 and then there are the helpers 1 and 2. Helper 2 is always 4. Helper 1 stores the last value of counter 1.

So at the beginning counter 1 and helper 1 have the same value. In the dispatcher you compare the values of counter 1 and helper 1. If you change the value of counter 1 the dispatcher will fire. It will set counter 2 to the value of counter 1. Then it will add the value of helper 2 (here: 4) on top. Finally helper 1 is set to the value of counter 1.

So this will add 4 as you wished and it will always fire whenever you change the value of counter 1. See attechments.

Hello.

Yes, I know it fires only when there is a change. 
I tested your suggestion, and it works fine!  So now I will implement it to my layout.  It should work nicely

Thanks again, for super help, Stefan!

Per.
