From 7eb047b2417d9b6cc3690fba75a50967a315955c Mon Sep 17 00:00:00 2001 From: wm4 Date: Tue, 21 Oct 2014 23:55:32 +0200 Subject: command: make reverse cycle_values match up with forward one The behavior of reverse cycling (with the "!reverse" magic value) was a bit weird and acted with a "delay". This was because the command set the value the _next_ command should use. Change this and make each command invocation select and use the next command directly. This requires an "uninitialized" special index in the counter, but that is no problem at all. --- DOCS/man/input.rst | 2 +- player/command.c | 7 +++---- 2 files changed, 4 insertions(+), 5 deletions(-) diff --git a/DOCS/man/input.rst b/DOCS/man/input.rst index b0a7ed2a2e..05cc9da562 100644 --- a/DOCS/man/input.rst +++ b/DOCS/man/input.rst @@ -419,7 +419,7 @@ Input Commands that are Possibly Subject to Change The special argument ``!reverse`` can be used to cycle the value list in reverse.
