Expression Gate Documentation

[Syranide]

Everybody look at the Wiki page. http://www.garrysmod.com/wiki/?title...xpression_Gate
I'm working on a wiki page for the expression gate. As you can see I am writing a guide to the gate. Please help improving![/b]

Ah, that looks terrific!
(Especially "Syranide = God" )

Basically, I would hook it up to a pulser to simulate a frequency variable. It would check if the frequency was true, so if I had a ticktime of .001, it would have a frequency of 1000.

That's the reason I wanted to see if Input1 == 1 -> Input2 == 1 -> Out = 1; would work. So I can make something like

~Frequency ->
*rest of the Expression code*

To simulate the Frequency variable on the CPU.

Nevermind...[/b]

Yes, the expression gate is clocked using an external pulser instead of an internal as is the case with the CPU.
The way I do is like you describe there, although Frequency is slighty misleading because it implies a value... but anyway, yes that's how you do it if you would like it to run 1000 times per second, just know that the it is not possible to do it because the wirelib does not support it, I think you can do something like 50 per second at most (and there would be no reason to do otherwise either because no other component can work faster), a simple way of setting it up is using a timer instead as clock, as it would then update as fast as possible I believe.

And doing ~Clock would only update it when the clock has updated meaning that it won't speed up if the other inputs are changed.

How would you do a value range? like.. the value can only be between -1 and 1

Value < -1 -> Value = -1;
Value > 1 -> Value = 1;

or even simpler

Value = clamp(Value, -1, 1)

which is the same as

Value = max(-1, min(1, Value))

I suggest the second, the others as just given as examples.
Cheers!

I have found a VERY useful tool if you guys like to use the expression gate for formulas

Currently im using it to tweak the power stroke of a racing machine.

Hi, is there an code that negates a value?

Also, how do I do a greater than / less than gate?

Thanks!

Negate: (Simple arithmetic)

A = -A

Greater than: (C will be 1 if A is greater than and 0 otherwise)

C = A > B

In terms of a the code for creating an actual greater than gate it would be

Inputs: A B
Outputs: Out
Out = A > B

Hope it helps, just ask if you have any more questions!

Thank you very much, so simple now Iv seen it.

But about The greater than gate, I just want something with a Value Range but outputs 1 if its between it and 0 if its not in the value range.

Cheers

thats an is in range(inclusive) gate (exists under comparison)
and would be

Inputs:Min Max Value
Outputs: Out
Out = ((Value < Max && Value > Min) ? 1:0)

[Syranide]

Aha!
Hmm perhaps I should add this to the available functions, anyway, I don't want to be picky, but I want to show people how you can do it in the "intended way", that is now using (B ? 1 : 0) which is the same as just writing B (and yours is exclusive ):

inclusive in-range gate (minimal version)

Inputs:Min Max Value
Outputs: Out
Out = Value => Min && Value <= Max

Yah and a very Simple Delta is this:

O@O
O = $A
