Time dependent variables
|
Is there a way to make a variable change if a conditional trigger does NOT occur within a set amount of time?
#TR {line1} {var=1}
#COND {line2} {var=0}
(great)
line2 almost always occurs within 2 seconds of line1. However when it does not, I would like to be able to assume that it did, and set var=0. Any advice on how I could do this?
#TR {line1} {var=1;#ALARM +2 {var=0}} messes up if I recieve two line1's within two seconds, because I only want var=0 after two seconds have passed from the last line1, or if line2 is recieved.
Hope this makes sense to you. |

If you always want var=0 either when line2 is received, or if its not recieved within 2 seconds, for var=0 to be true anyway,
#tr {line1} {#var var2 0;#alarm 2 {#if (@var2=0) {#var var1 1;#var var2 1} {#noop}}}
#tr {line2} {#var var1 1;#var var2 1}
should work
sorry, to clarify, your orginial var i have called var1 |

since you want the var to change wheter you get the line or not after two seconds you can use a #COND trigger with a wait state
#TRIGGER {line1} {var=1}
#COND {} {var=0} {wait|param=2000}
The first Trigger set var to 1 upon recieveing the line
The Conditonal waits 2 seconds (please note this is NOT the #WAIT command) then sets the var to 0 note the blank pattern |

#TR {line1} {#VAR var1 1}
#COND {} {#VAR var1 0} {wait|param=2000}
#TR {line2} {#VAR var1 0}
How would this behave if I recieved two "line1" from the MUD within two seconds of each other? Would it wait two seconds after the first "line1" or after the most recently recieved match to change the variable? If "line2" is recieved before the two second wait completes it will change anyways, which is what I want.
Made up mud output:
[0:00:00]:line1 -> var1=1, waiting 2 seconds
[0:00:01]:line1 -> var1=1, waiting 2 seconds
* now, would var1=0 at [0:00:02] or [0:00:03]?
[0:00:00]:line1 -> var1=1
[0:00:01]:line2 -> var1=0
[0:00:02]: -> var1=0 (no change) |

It would only fire once as the trigger is *waiting* in its second state and not the first |

Thanks for making that clear. Unfortunately I don't think it will work for what I'm trying to do.
I'm trying to figure out how to get it to change two seconds after the most recent line1, or if line2 is recieved. The challenge is that line1 and line2 may both reoccur within those two seconds.
#tr {line1} {#var var1 0;#var var2 0;#alarm +2 {#if (@var2=0) {#var var1 1;#var var2 1} {#noop}}}
#tr {line2} {#var var1 1;#var var2 1}
I think the above would work, except that a second occurance of line1 would start seperate #alarm, where I would prefer it to just restart the same timer. Can the Tick timer be used to solve this by possibly resetting the tick to 2 seconds at every line1, and having line2 and the Tick changing the variable? |

Name your alarms and they will overrite
#alarm "varAlarm" {+2} {#if (@var2=0) {#var var1 1;#var var2 1} |
