From ffd5faaf020fa5f8504c2b8b90e5daf93ed1edaf Mon Sep 17 00:00:00 2001 From: tobigun Date: Mon, 28 Jan 2008 09:31:22 +0000 Subject: TTexture.Z was never initialized (TTextureUnit.LoadTexture). In FPC (not in delphi) this resulted in a floating-point error when calling glVertex3f(x1, y1, z) in DrawTexture (UDrawTexture.pas) git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@807 b956fd51-792f-4845-bead-9b4dfca2ff2c --- Game/Code/Classes/UTexture.pas | 2289 ++++++++++++++++++++-------------------- 1 file changed, 1145 insertions(+), 1144 deletions(-) (limited to 'Game') diff --git a/Game/Code/Classes/UTexture.pas b/Game/Code/Classes/UTexture.pas index 82dedf45..770b88bd 100644 --- a/Game/Code/Classes/UTexture.pas +++ b/Game/Code/Classes/UTexture.pas @@ -1,1144 +1,1145 @@ -unit UTexture; -// added for easier debug disabling -{$undef blindydebug} - -// Plain (alpha = 1) -// Transparent -// Colorized - -// obsolete?
