sdk - Stop a corona collision event from firing multiple times -


so want collision listener fire once. i've tried putting in if execute variables it's not elegant.

local function collideground( self, event )          local obj  = event.other          local phase = event.phase                 if ( phase == "began" )                          if obj == ground                 print("hit")              end          elseif ( phase == "ended" )            end         return true     end     player.collision = collideground     player:addeventlistener( "collision", player )

collision listener not touch event or tap event. whenever player object awakes collision event, collideground called , that's why provided 3 different event.phase.

any collision event handler returns true stop further propagation of collision event, if there further listeners otherwise have received it. allows further limit number of events created , passed lua side. while individual events not expensive, large numbers of them can affect overall performance, limiting event propagation practice.

i think collision detection somehow achieve goal. 😉

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
