From 9d5d74d826ceaa227c3d1684dde0743c08ae1175 Mon Sep 17 00:00:00 2001 From: Samuel Barney Date: Tue, 5 Nov 2013 14:01:51 -0700 Subject: Added more documentation. Changed cTracer::Trace to return a bool instead of an int because it was only returning 1 or 0 anyways. --- source/Tracer.cpp | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'source/Tracer.cpp') diff --git a/source/Tracer.cpp b/source/Tracer.cpp index d7a613891..4d036486e 100644 --- a/source/Tracer.cpp +++ b/source/Tracer.cpp @@ -131,12 +131,12 @@ void cTracer::SetValues(const Vector3f & a_Start, const Vector3f & a_Direction) -int cTracer::Trace( const Vector3f & a_Start, const Vector3f & a_Direction, int a_Distance) +bool cTracer::Trace( const Vector3f & a_Start, const Vector3f & a_Direction, int a_Distance) { if ((a_Start.y < 0) || (a_Start.y >= cChunkDef::Height)) { LOGD("%s: Start Y is outside the world (%.2f), not tracing.", __FUNCTION__, a_Start.y); - return 0; + return false; } SetValues(a_Start, a_Direction); @@ -157,7 +157,7 @@ int cTracer::Trace( const Vector3f & a_Start, const Vector3f & a_Direction, int // check if first is occupied if (pos.Equals(end1)) { - return 0; + return false; } bool reachedX = false, reachedY = false, reachedZ = false; @@ -236,7 +236,7 @@ int cTracer::Trace( const Vector3f & a_Start, const Vector3f & a_Direction, int return true; } } - return 0; + return false; } -- cgit v1.2.3
