From: Mikko Rasa Date: Fri, 17 Sep 2021 23:56:23 +0000 (+0300) Subject: Specify underlying type for format descriptor enums X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=a4d83d3748cdde8cf30683d36a040d3dfacfd693;p=libs%2Fgl.git Specify underlying type for format descriptor enums This makes it possible to use them directory in the associated format structs without increasing their size. --- diff --git a/source/builders/primitivebuilder.cpp b/source/builders/primitivebuilder.cpp index ca16fcde..85c695c3 100644 --- a/source/builders/primitivebuilder.cpp +++ b/source/builders/primitivebuilder.cpp @@ -59,10 +59,9 @@ PrimitiveType PrimitiveBuilder::get_type() const void PrimitiveBuilder::vertex_(const Vector4 &v) { - const VertexFormat &format = array.get_format();
