FIX: Make sure we respect the default button press point for triggers, same for Touchscreen's tap delay time and tap radius squared by K-Tone · Pull Request #2186 · Unity-Technologies/InputSystem

K-Tone · 2025-05-21T10:10:02Z

Description

This is an attempt to fix the problem where in Editor we would really apply the default input settings correctly. Like, we would read them, but we wouldn't correctly update the derived static properties so whenever that happens, we have issues like the default button press point being incorrect.

Looking at code, I believe it's not just the default button press point that was incorrect, I think all of these folks were incorrect too (though the bug report won't mention them):

            Touchscreen.s_TapDelayTime = settings.multiTapDelayTime;
            Touchscreen.s_TapRadiusSquared = settings.tapRadius * settings.tapRadius;
            // Extra clamp here as we can't tell what we're getting from serialized data.
            ButtonControl.s_GlobalDefaultButtonPressPoint = Mathf.Clamp(settings.defaultButtonPressPoint, ButtonControl.kMinButtonPressPoint, float.MaxValue);
            ButtonControl.s_GlobalDefaultButtonReleaseThreshold = settings.buttonReleaseThreshold;

Testing status & QA

                Object.DestroyImmediate(m_Settings);
-            m_Settings = state.settings;
+
+            settings = state.settings;


So the theory here is that using the property instead of a direct setter makes sure we update all the derived data (static caches) -- that happens in ApplySettings that is ignored in here.

Ah, good catch, since the property setter triggers the apply settings.

Just made this PR ready for review because the CI redness on iOS and tvOS looks caused by xcodebuild timing out while waiting for some update or whatever. Not related to this change.

ekcoh

Approving this fix but it would be great if we could add the missing test coverage for this, which seems unrelated (as you say) to the specific setting but relates to the restoration of settings after e.g. a domain reload. I wonder if we could get it covered by exiting and then re-entering playmode from a test.....

Always good to fix a typo.

Did not forget this one, will try to review it today/tomorrow

Pauliusd01

LGTM, only one note though. Should these UTR version changes go in with this PR? I think you added them to test if it solves your CI problems? I wouldn't mind but just checking

K-Tone · 2025-06-02T08:25:38Z

In the end, I think I would send the UTR change with this PR because otherwise it's very painful to get a green automation run on this PR otherwise

K-Tone · 2025-06-02T08:27:52Z

I didn't make a test here in the end, I think I just don't know how to make a meaningful one without making a new test project with the updated defaults
