A countdown

[Lieutent Slappy Moose]

I am making a trebuchet which is almost fully automated. I am using a series of winches to swing the arm, but I am using an expression and a timer to trigger everything.

How can I make it so for "X" seconds, the winches pull at a rate of "Y?"

Can I do this in the expression, or do I need a different set of chips?

If there is some sort of "countdown" chip, like a reverse of the timer, can you tell me what it is (or how I can make one) because if there is I know a way to solve my problem.

Thanks.


Actually, I just thought of a solution. I can just subtract the timer from 60, giving me "time left" which I can manipulate into winch power.

Still, if anybody has any other ideas please share them. I can always use different/simpler methods of doing things.

@NCount Down
@IStart Reset Max Min
@OTime
interval(100)
Reset -> Time = Max;
Start & Time & clk() > Min -> Time -= 0.1;
Time < Min -> Time = Min;

Acurate to the 10th of a second, it counts from the maximum value to the minimum value. It also has a built in system not allowing it to go underneath the minimum... which the version described above doesn't easily allow. Obviously, Min and Max could be replaced with constant values such as 60 and 0...

Thanks, I'll give your way a shot.

I've actually found an interesting way to do a countdown, and convert the time into length and such. If it doesn't work, I'll try yours.



Yeah, looks like I am gonna need your timer after all heheheh. The way I used mine doesn't work for certain things.

Thanks, turns out I really really needed it.

Hey, another question.


Is it possible to reverse the timer? So if the input is 1, it counts from 0 to 60, but then when the input is -1, it counts from 60 to 0.
I'm using the expression code from above, and I can't for the life of me figure out how to reverse the timer :C

Thanks in advance for any help. I really appreciate it.

N@CountDown
I@Start Reset Max Min Dir
O@TimeOut
interval(100)
Reset -> Time = Max;
Start & Time & clk() > Min -> Time -= 0.1;
Time < Min -> Time = Min;
TimeOut=(Dir==1?Time:Max-Time)

N@ I@ O@ were the wrong way before

Last line checks if Dir (direction) is equal to 1
If yes -> Timeout = time
If no -> Timeout = max - time

Hope this is any help to you.

I'll try that, and thanks.

I think I get what the last line does, thanks for the explanation.


Hmm, it didn't work.

I may be implementing it wrong, but it either seems to instantly go to max or min, or just stay at one of those.


I'm gonna try a different method.

Thank you anyway, though, I appreciate any advice I can get.

Oh wait...
You mean that the values of the start button are -1 and 1 ?
I created a extra switch to turn it around. Which makes it go instantly.

N@CountDown
I@Start  Max Min Reset
O@Time
interval(100)
Start==1 & clk() & Time<Max -> Time += 0.1;
Start==-1 & clk() & Time>Min -> Time -= 0.1;
Time<Min->Time=Min;
Time>Max->Time=Max;
Reset->Time=Min;

This code works with a toggle button (-1 Off / 1 On ) connected to start
It should smooth go up and down. It doesn't matter at what moment you toggle Start.
Push button -> it counts to max
Push button again while it's still counting to max -> it counts back to min.

I also added two extra lines to make absolute sure that Time is always between Min And Max

Reset sets the timer back to minimum...Instant.

N@CountDown
I@Start  Max Min
O@Time
interval(100)
Start==1 & clk() & Time<Max -> Time += 0.1;
Start==-1 & clk() & Time>Min -> Time -= 0.1;
Time<Min->Time=Min;
Time>Max->Time=Max;

Same code without reset. Not sure if you need a reset function.

Tested ingame.. works like a charm

Thank you so much!

I had been trying to figure out how I could have two different start values, which would change whether time was added or subtracted, and you just told me how!

I can't tell you how much this will help me.



I tried it, and it works. This code will save me so much trouble with everything I make! I am currently using this code very a type of elevator, but this will help me with so much more, especially in factories...

I appreciate you taking the time to help me!
