Creating Estims - Definitions and Functions

scrumpbus22

Hello, I've been trying to wrap my head around the way crafting estims works, I'm a Coyote users so I'll be approaching it from that angle.

Some of the stims have values defined that make it easier or harder to interpret what they mean, Pain stims having a channel intensity of 1 vs. teases at 15. Two different edging stims at 3 and 35 intensity. Just looking to outline where things are less clear and might be useful for others as well.

Channel Intensity - Is this the base intensity of the stim being crafted?
Frequency - is there a cap? Most of the base stims are either at 5 or 10 for frequency. I assume the 4 fields mean the stim goes from A to B to C to D across the duration of the stim, or does it iterate through the numbers on repeat every X seconds?

Base Time, Delay, Speed, Max Speed make sense on their own. Does the existence of Speed and Max Speed mean that Speed is minimum speed?

Then the Graph and where the maths come in:
If a graph goes from 0 to 50 then back to 0, how does that work with the Channel Intensity value and then how does that scale with the device settings? I assume the Y value on the graph is more of a % based thing, but is that a % of the Channel Intensity or the Device's Intensity?

Example:

Device is set to 50 intensity
Stim Channel Intensity is set to 10 intensity
Graph goes from 0 to 25 to 0

What is the device outputting?

0 to 12.5 to 0 (25% of the Device's 50 intensity)
0 to 15 to 0 (25% of the Device's 50 intensity combined with the 10 Stim Channel intensity making it 60)
10 to 22.5 to 10 (25% of the Device's 50 intensity, then add 10 on top from Stim Channel intensity)

Then for pain_shocks it's 1 second, no data, 100 channel intensity. Is that to simulate 1 second at 100% Device Channel intensity?

Thanks for your help!

scrumpbus22 Channel intensity is indeed the base value from which the stim values are calculated. For example, a stim with an intensity of 10 and a channel intensity of 50 will result in an intensity of 5.
For a pain stim, it's the same, but it uses "Pain Intensity" as the base value instead of channel intensity.
This means that if you set channel intensity to 50, and a stim has an intensity of 100, your Coyote 3 device will be set to an intensity of 50 out of 200. Same logic for pain intensity.

Frequency: It's capped at 240. Most of the stims are at 5–10 because above that it starts to feel uncomfortable (at least for me) and falls in the tetanic contraction range.
The way it works is that it's an array of 4 values sent every 100ms, and thus played during those 100ms. I intended to let the user create sequences for frequencies, allowing for richer frequency modulations, but I didn't have time to test it properly before the release.

The graph: It works the same as the intensity of the stim. But when there is a sequence, the stim intensity is not used. This isn't clear on the interface, but instead of using the stim intensity as the main value, it uses the values set in the sequence.
So for your example: 0 → 50 → 0 over one second means that the value will gradually increase from 0 to 50 over 0.5s, then gradually decrease back to 0 over 0.5s.
And the 50 on the graph means 50% of channel intensity (so 25 if we're still at 50 channel intensity — that's 25/200 of your device intensity).
And yes, speed is used as the minimum speed.

For the pain shock: There is no sequence, so it plays at 100% of the "Pain Intensity," with no time limit. Same as before — let's say you've set Pain Intensity to 90, then it will set your device to 90/200 intensity.
Shocks are not always at 100%, so a 70% shock will be a calculation between a floor value and the max value (Pain Intensity).

Actually, it's obviously limited in time, but not by the stim itself — it's limited by Eudaimonia's way of handling pain shocks.

I think a lot of the confusion comes from the Intensity slider not being disabled when adding a sequence in the graph.

I hope this is helpful!

Yep, that makes everything perfectly clear, thank you!

Something else I just realized I'm not entirely certain how the AI amplifies the stim based on intensity 1-5.

Is "Intensity 1" equal to 20% of the device's channel, 5 = 100%?
Stim Strength = Device Channel Intensity * Graph % Intensity * (AI Intensity * 0.2)
This would make sense to me, but wanted to make sure.

scrumpbus22 It's a calculation between the intensity (1–5) and the speed (0–100), which then directly adds to the device intensity.

For example, if your channel intensity is set to 50, a 4/5 intensity stim at 70% speed will increase it to ₆₅. Increasing the speed tends to lower the intensity, so I compensate for it a bit.
