android - Difference between libgdx Stage and Screen -


i'm making game, , see in tutorials people using stage class, , others using screen class, can't figure out diference.

a stage holds actor instances , updates/animates them , manages hit-detection among them. root of scene2d "scene graph" api. stage one way of managing list of objects draw, state on screen (textures, animation state, size, etc), , interactions user. provided stage code in libgdx oriented towards ui elements buttons , lists, core flexible enough contain game elements too.

a screen represents 1 full-screen ui "page". example, might have "main menu" screen, "options" screen, "main game" screen , "end credits" screen. screen instances managed game instance. when used game screen objects receive standard libgdx lifecycle events callbacks (pause, resume, resize, render, etc).

there no concrete relationships between stage , screen in libgdx. easiest think of example "main menu" screen implemented stage manages buttons in main menu. when user hits 1 of buttons, game might switch main game-play screen, , release of resources held main menu. game-play screen might use stage or might use raw opengl implement game.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
