Images resources searched with a local path

[David-Estevez]

Images resources searched with a local path (use ResourceFinder instead).

@jgvictores juansays: segfault if not found

EDIT: list of files with local paths

• testMockupAudioManager.cpp
• testSDLAudioManager.cpp
• DeadScreen.cpp
• testDeadScreen.cpp
• testDeadState.cpp
• InitScreen.cpp
• testGameScreen.cpp
• testGameState.cpp
• testRdMockupImageManager.cpp
• testRdProcessorImageEventListener.cpp
• testRobotDevastation.cpp

@jgvictores which is the default folder in which the resources are installed / looked for?

For instance, which folder corresponds to the following piece of code?

yarp::os::ResourceFinder rf;
rf.findFileByName("../sounds/RobotDevastationBSO.mp3")

[jgvictores]

yarp::os::ResourceFinder is a rather complex, as seen in robotology/yarp#336, which points to "the painful details http://wiki.icub.org/wiki/YARP_ResourceFinder"

Apart from that piece of code, two intermediate important of lines from robotDevastation/main.cpp affect ResourceFinder. Combined, this results in:

yarp::os::ResourceFinder rf;
rf.setDefaultContext("robotDevastation");
rf.setDefaultConfigFile("robotDevastation.ini");
rf.findFileByName("../sounds/RobotDevastationBSO.mp3");

The yarp_install CMake directive copies/installs the files so they can be found by the ResourceFinder. Following the RobotDevastationBSO.mp3 example, the relevant lines of robotDevastation/share/sound/CMakeLists.txt are:

set(appname sounds)
file(GLOB mp3s ${CMAKE_CURRENT_SOURCE_DIR}/*.mp3)
yarp_install(FILES ${mp3s} DESTINATION ${RD_CONTEXTS_INSTALL_DIR}/${appname})

On my configuration, yarp_install copies/installs the files so they can be found by the ResourceFinder relative to robotDevastation/build/share/rd/contexts/robotDevastation or /usr/local/share/rd/contexts/robotDevastation/ (note that this is where the robotDevastation.ini file the third line of cpp above specifies lies).

@jgvictores Fonts are currently accessed though their absolute path (i.e:

const std::string rd::DeadScreen::FONT_PATH = "/usr/share/fonts/truetype/freefont/FreeMono.ttf";

)

Is this ok or does it involve any risks?

[jgvictores]

const std::string rd::DeadScreen::FONT_PATH = "/usr/share/fonts/truetype/freefont/FreeMono.ttf";

Looks totally dangerous and non-portable. If size and license are not an issue, I'd at least think of distributing it with robotDevastation.

Everything fixed in 00f62ce

Path should be something like "../images/image.png"

Fixed in fa4dd65
