OFS Simulator3D Mod: Surge & Sway Fix - v1.6

Falafel · September 16, 2024, 9:47am

If your measurements are correct, apply the following code in Simulator3D.cs, starting line 250.

		strokerMesh.GlobalRotate(Vector3.Right,
			Mathf.Deg2Rad(
				Mathf.Lerp(35.0f, -35.0f, pitch)
			)
		);

		strokerMesh.GlobalRotate(Vector3.Forward,
			Mathf.Deg2Rad(
				Mathf.Lerp(-30.0f, 30.0f, roll)
			)
		);

		strokerMesh.RotateObjectLocal(Vector3.Up, 
			Mathf.Deg2Rad(
				Mathf.Lerp(-120.0f, 120.0f, twist)
			)
		);

		strokerMesh.Translation = new Vector3(
			Mathf.Lerp(0.667f, -0.667f, sway),
			Mathf.Lerp(-1.0f, 1.0f, mainStroke),
			Mathf.Lerp(0.5f, -0.5f, surge)
		);
	}
}

About the twist, it varies according to the servo.

I measured mine but got different results.
up/down: -6cm to +6cm (12cm)
left/right: -4cm to +4cm (8cm)
forward/backward: +2.75cm to +2.75cm (5.5cm)
pitch: -28.5° to +28.5° (57°)
roll: -19° to 19° (28°)

Mine is the customized SR6 with metal bearing arms from FunOSR.
@Tempest May I ask what’s the roll and pitch range for a default SR6? Is it the same as the OSR2+?

Tempest · September 16, 2024, 10:53am

This is how I set up the inverse Kinematics, as in the maths that’s going on inside the ESP32 to calculate the servo angles:

The design is based around a modified Stewart platform with six servos driving six arms, which connect to the receiver via six linkages. The arrangement gives a theoretical total movement range of 120mm in the up-down direction and 60mm in the left-right and forward-backward directions. The receiver can simultaneously also rotate in roll and pitch by approximately ±30 degrees.

So your values are about right. It will vary a bit because there’s variation between different models of servo.

Update: V1.6

Changed Pitch and Roll of the model to 30° to better match an actual SR6. (Previously 45°)

Ratattack15 · September 17, 2024, 5:27pm

Dunno if it hasn’t processed yet but I can’t see the update, still shows the last release being v1.5

Falafel · September 18, 2024, 9:45am

should now be publised

Falafel · September 18, 2024, 10:35am

Just found out that the angles are different for SR6 and OSR2+.

My OSR2+ with Khrull’s firmware:
Pitch: -25° to 25° (50°)
Roll: -29° to 29° (58°)

I think there might need a way to switch between the two device.

Ratattack15 · September 18, 2024, 5:13pm

Sure about that? As you asked Tempest if they were the same which they didn’t say yes to.

Falafel · September 19, 2024, 6:34am

I’m sure they are different by design? The OSR2+ has wider pitch and roll range than the SR6. Correct me if I’m wrong @Tempest @soritesparadox.

I think what this means for the simulator is there needs to be a way to toggle between SR6 and the OSR2+. I may do this by detecting if there exists .surge and .sway scripts.

Why I load FunscriptSimulator3D Inside ofs it shows a link error

Falafel · September 20, 2024, 9:33am

You shouldn’t load it inside OFS. It’s a separate application that communicates with OFS via websocket.

Blue1 · September 29, 2024, 2:15pm

Is there a guide for new users of this program? As someone who used to only use OFS, it’s hard to know the connection between OFS Simulator3D Mod and Gobot and how to link it.

MrRadicalsheep · September 29, 2024, 8:14pm

Yes I was wondering if someone could help, I am strugling to get the background to be transparent for what is on screen, and also to change the websocket connection.

Transparency issue:

Connection issue:

I’m not sure where to set the websocket connection, or if it’s correct. I put it in the time stamp server URL, under export window. Help would be appreciated.

@Falafel @codeScripter
You guys seem to better understanding of the software than me. I already hve the 3D model as I want just need insturction on where to change stuff to make it work, thanks! :))

codeScripter · October 1, 2024, 3:15pm

Just modify it here

Falafel · October 1, 2024, 3:20pm

Try this option under project settings.

Falafel · November 8, 2024, 1:48pm

can someone tell me if roll is inverted in v1.6?

smeedler · February 13, 2025, 2:49pm

anyone have an idea how to fix this? dependencies are all in the listed locations, but not found by godot. “fix dependencies” does nothing. searching suggests this is a godot bug.

Edit: I was a silly billy and had the standard version of Godot instead of the .NET version

Dimava · February 28, 2025, 6:33am

Can you add a version with clitoris on front and a tongue on the back as a default model?
It’s way easier to understand then those two squares

Ah I see
Still would’ve like to have a dot on the front

Hmm
I think I should make my script generator to scale L0 based on distance to entry
so it doesn’t fall off when there is a roll on 100% L0 (cuz I set it to “barely touches”)

Falafel · February 28, 2025, 6:49am

I don’t think that’s a huge problem, you can make L0 y axis and it still make sense. The distance visualiser was added due to the concerns of a careful scripter who voiced worries of slipping out (In reality you can prevent slipping with the smart limit in MFP).

It’s a good idea. If you just add a sphere mesh as a child to the cylinder.

I’ve lost the Godot environment I built for myself so I’m not in the mood to update it soon

Dimava · March 1, 2025, 4:56pm

Could you also add ability to rotate L0 the not soon when you make it?
