From 2f51f25369ef2a533fd5e3f421a2f4ae87846506 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Emil=20Seger=C3=A5s?= Date: Thu, 2 Jul 2015 14:22:43 +0200 Subject: [PATCH] Refactorized demo platform integration to better suit game loops. Makes it easier to reuse the demo platform glue for other projects. Especially game loops or platforms where rendering is set up in a different order. TB API change: Removed language file path from tb_core_init. g_tb_lng->Load should be called manually after tb_core_init instead. --- Demo/demo01/Demo.h | 26 +++--- Demo/demo01/Demo01.cpp | 94 +++++++++---------- Demo/demo01/ListWindow.cpp | 7 +- Demo/demo01/ListWindow.h | 4 +- Demo/platform/Application.cpp | 46 ++++++--- Demo/platform/Application.h | 67 ++++++++++---- Demo/platform/port_glfw.cpp | 170 ++++++++++++++++++---------------- src/tb/tb_core.cpp | 3 +- src/tb/tb_core.h | 2 +- 9 files changed, 237 insertions(+), 182 deletions(-) diff --git a/Demo/demo01/Demo.h b/Demo/demo01/Demo.h index e45c037..5d3ecd6 100644 --- a/Demo/demo01/Demo.h +++ b/Demo/demo01/Demo.h @@ -12,19 +12,21 @@ using namespace tb;
