Unigine::BootConfig Class
| Header: | #include <UnigineConfig.h> |
A singleton that controls the Engine startup configuration and enables you to customize the boot screen.
Notice
Fonts, textures, or any other resources used in the boot screen cannot be packed into an UNG archive.
Usage Example#
By using the BootConfig class, you can customize the boot screen and change the startup settings and save them to the configuration file for the next engine start-up. For example:
AppSystemLogic.cpp
Source code (C++)
#include "AppSystemLogic.h"
#include <UnigineConfig.h>
#include <UnigineConsole.h>
using namespace Unigine;
/* .. */
int AppSystemLogic::shutdown()
{
// set the window title
BootConfig::setWindowTitle("Project Name");
Console::setString("starting_world", "my_world");
// customize the boot screen
BootConfig::setScreenWidth(960);
BootConfig::setScreenHeight(540);
BootConfig::setScreenBackgroundColor(Math::vec4_black);
BootConfig::setScreenTransform(Math::vec4(1.0f, 1.0f, 0.5f, 0.5f));
BootConfig::setScreenThreshold(16);
BootConfig::setScreenTexture("textures/boot_screen.png");
BootConfig::setScreenText(" \
<p align=\"center\"> \
<font color=\"#ffffff\" size=\"64\"> \
<xy x=\"%10\" y=\"%50\"/>Helicopter \
</font> \
</p>");
BootConfig::setScreenMessageEngineInit(R"( \
<p><font size=\"24\" color=\"#777777\"> \
Engine initialization. \
</font></p>)");
BootConfig::setScreenMessageFileSystemInit("Custom message for file system initialization.");
BootConfig::setScreenMessageMaterialsInit("Custom message for materials initialization.");
BootConfig::setScreenMessagePropertiesInit("Custom message for properties initialization.");
BootConfig::setScreenMessageShadersCompilation("Custom message for shaders compilation.");
BootConfig::save();
return 1;
