java - LibGDX button not working properly? -

i confused @ moment. know feeling when app should working fine, isn't reason?!

in app's playstate, have 3 states, defined variable "currentstate".

currentstate = 0 = running

currentstate = 1 = pause

currentstate = 2 = game over

public class playstate extends state { public static final int tube_spacing = 420; private static final int tube_count = 4; public static spritebatch batch;  public static preferences prefs;  private array<tube> tubes;

i have different class created buttons playstate class, called playstatebuttons.

the "resume" button supposed resume game pause running, when click it, resumes game, "boop" sound plays continuously forever , when bird collides anything, doesn't stop, displays game on menu while touching objects.

my theory "resumes" bird if resume button pressed, why cannot die , keeps playing sound. problem is, why hell doing that?!

once buttons clicked , set boolean pressed, there nothing in code ever sets pressed booleans false. once press button, pressed down forever.

this complicated , error prone way of handling these buttons anyway. convoluted have render method poll buttons see ones have been pressed.

get rid of booleans whether buttons pressed, , if-pressed cases in handleinput() method. each button's click listener should call method changes state, plays sound, etc. way code structured, need pass instance of playstate platstatebuttons constructor, various clicklisteners can access it.

as aside, buttons in libgdx behave more naturally if use changelistener on them instead of clicklistener.
