how can make impulse vibration ?

[hoyachoe]

Thank you for your program.

However, I have a question.

When playing with an Xbox controller, the throttle trigger produces an impulse vibration at the point where the car’s tires begin to power-slide / lose traction. That feedback feels very natural.

When using your program with a DualSense controller, is it possible to reproduce a similar effect — trigger feedback specifically at the tire slip / power-slide point?

I have tried changing the settings extensively, but it seems difficult to reproduce that behavior.

Another program, Racing DSX, can somewhat express tire slip through trigger movement similar to an impulse trigger, but the effect feels very rough and harsh rather than refined.

Do you think this could be improved? If so, what would be the best approach?

I need to try it with xbox to give the same effect.

However, if the car slips while playing with steam, the haptics already vibrate. When the car is sliding

Also, the ABS effect actually serves a similar purpose, I read from the data that the car wheel locks and the car starts to slide.

Just FYI, the haptics do not vibrate when playing with steam using a Dual Sense controller. The Steam Controller doesn't offer any vibrations for PS5 DualSense controllers unfortunately. For this game, that is.

The left and right rumble motors are vibrating on my end.

TRY:

Enable DualSense vibration in Steam, and also enable vibration in the Accessibility tab (in game).

The only thing that didn't work for me was the adaptive trigger

[jmac122]

That's weird, I definitely have Playstation Accessories installed and even made sure my controller firmware is updated. I wonder if the Steam Controller plugin is preventing it, because it always shows an Xbox controller picture I click the "controller" icon on the Steam game? Maybe I need to switch the steam controller?

General rumble works for me with steam input, but I haven't been able to get the triggers to vibrate either. I'm also on Linux and wasn't able to install Playstation Accessories so I'm not sure if that would have fixed it. In any case, if it's not super complicated I would definitely appreciate such a feature .

Have you tried the installation steps for Linux? My app should work on Linux as well. it's python anyway.

If you feel a vibration when toggling these options on and off, it means the app is working.

In that case, all you need to do is configure the UDP ports within the game.

[klisurovi4]

You misunderstood me, your app works perfectly fine, I'm loving it. I definitely feel the haptics from the ABS, redline, etc. I'm talking about how with Xbox controllers, when the car starts sliding, the right trigger vibrates to let you know. Steam Input doesn't do that for Dualsense controllers, it seems to only support the general full controller rumble so there's basically no feedback when the car loses grip. Maybe on Windows that gets fixed with the Playstation Accessories app, but as far as I can see there's no way to install that on Linux.

[HamzaYslmn]

no feedback when the car loses grip.

Hmm, here’s my experience:

I don’t know the difference between Rumble and Haptic—maybe I just don’t get it.
But when the car hits the ground or skids, the controller gives off a very slight vibration.

R2 and L2 weren’t working at all, so I fixed that with my special effects. I didn't use any pre-made effects from the game (it doesn't produce any output anyway). I wrote all the effects myself.

It looks like all the effects on the DS are working for me now.

I wonder what’s missing on Linux?

Is the R2 supposed to vibrate when the car skids, or are the left and right rumble motors inside supposed to do it?

Like a year or so ago I had an Xbox Elite controller, but I believe it worked the same for regular Xbox controllers too. Both triggers had vibration motors in them. Nothing as fancy as the Dualsense adaptive triggers, but they could vibrate independently of the rumble motors in the controller's body. When you press the brakes too hard and the wheels lock up, the left trigger vibrates. If you give too much gas and get wheelspin, the right trigger vibrates. The former is emulated pretty well, by the ABS rumble in your app, but I am missing the latter. The controller does vibrate slightly when the car enters a skid, but the problem is that it also vibrates for other reasons, like for example if your RPM is high (and if you are sliding it probably will be) so it's hard to identify a slide by the vibration alone.

As far as Rumble vs Haptic, haptics are pretty much all the feedback that depends on your sense of touch, it's usually defined as controlled vibrations at set frequencies and intervals to provide a sensation representative of an in game action. Rumble is just steady vibration, so it's is a subset of haptics. The whole controller vibrating when you are driving at very high RPM would be rumble, but the gear shift thump wouldn't be (it's still haptic feedback tho). Depending on how granular you want to go with the definition you can argue whether stuff like the ABS feedback is rumble or not, but that's the gist of it.

I didn’t specifically add this effect to the adaptive trigger. For example, there was that thing about the gas hardening when it came into contact with water, but I found those details unrealistic.

You can’t tell if the rev limiter kicked in or if the car is skidding.

When the car skids while braking, the ABS vibration already does this in the LT as well.

Most of the time, when the car skids, it downshifts and hits the rev limiter anyway.

So idk.

But if I can get some sponsors, I’ll get an Xbox controller and the game from Xbox and create something compatible for all users.

Have a PR coming that addresses this. Adds a wheelspin pulse effect on R2: when drive wheels exceed a slip-ratio threshold while the player is on the gas, R2 emits an M_PULSE_AB frame combining buzz with sustained reduced resistance, intensity scaled by slip severity.

Drivetrain-aware: FWD/RWD/AWD selects which wheels are monitored, so a FWD car drifting doesn't false-trigger from rear lateral slip. Min-throttle gate keeps it quiet during off-throttle slides.

Opt-in via a Controls tab toggle plus four numeric tunables in Settings. Will link the PR here once it's up.

Note, its specific to the dualsense controller, cause I too, only have that.

@klisurovi4 How does it make you feel now?

[klisurovi4]

I just tried it and it's pretty much exactly what I had in mind. Great work!

[HamzaYslmn]

I had in mind

I added different sliding vibrations to different surfaces.

What do you think is missing? you say "pretty much"
