From 686f82e51124747cbe650d04dfb053830b6660fa Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jan-Arve=20S=C3=A6ther?= Date: Thu, 23 Apr 2009 23:25:35 +0200 Subject: Fix a bug in the ease{In,Out}Bounce easing functions + small cleanup. The bug was in easeOutBounce_helper(), where the last else-block adjusted t wrong. It should adjust t so that the peak is at t == 0, but it adjusted it too little. The old code did t -= (2.25f/2.75f), but it should have been 21/22. The rest of the changes in that function is just simple mathematical rewrites (use a more readable fraction), and removed the b argument, since that was always 0. Finally, fixing the original bug also revealed a bug in the first line of easeOutBounce_helper(), where we always returned 1.0 for t == 1.0. That was wrong since it did not respect c. --- src/3rdparty/easing/easing.cpp | 34 ++--- tests/auto/qeasingcurve/tst_qeasingcurve.cpp | 183 +++++++++++++-------------- 2 files changed, 108 insertions(+), 109 deletions(-) diff --git a/src/3rdparty/easing/easing.cpp b/src/3rdparty/easing/easing.cpp index 340be86..9177c26 100644 --- a/src/3rdparty/easing/easing.cpp +++ b/src/3rdparty/easing/easing.cpp @@ -547,20 +547,20 @@ static qreal easeOutInBack(qreal t, qreal s) return easeInBack(2*t - 1, s)/2 + 0.5;
