From c316180c74e144a5faecfe30ab38c8e4e0ef9e91 Mon Sep 17 00:00:00 2001 From: tobigun Date: Mon, 7 Apr 2008 08:50:43 +0000 Subject: - Removed lrs resource usage in linux. Resources are copied to /usr/share/resources now. - Unified resource handling: call GetResourceStream (UCommon) to retrieve a resource. - Removed the lazarus dependency in the Makefile (it will also use the main .dpr-file now) - Now that the lazarus dependency is gone, the MacOSX and Linux version might use a shared codebase. git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@1013 b956fd51-792f-4845-bead-9b4dfca2ff2c --- Game/Code/Classes/UCommon.pas | 653 +++++++++++++++++++++++------------------- 1 file changed, 353 insertions(+), 300 deletions(-) (limited to 'Game/Code/Classes/UCommon.pas') diff --git a/Game/Code/Classes/UCommon.pas b/Game/Code/Classes/UCommon.pas index dce11ea0..5582c59b 100644 --- a/Game/Code/Classes/UCommon.pas +++ b/Game/Code/Classes/UCommon.pas @@ -1,300 +1,353 @@ -unit UCommon;
