ios - Add SKNode as trigger so that it does not affect other node's path -


so, wondering if possible add skspritenode , give physics body/properties such functions trigger. can thought of finish line in race. when pass line, point or something, path not physically/visually affected; pass right through it. sure possible, however, not know how achieve this. here have sprite:

var revolutionbar = skshapenode(circleofradius: 25) revolutionbar.alpha = 1 revolutionbar.fillcolor = skcolor.bluecolor() revolutionbar.physicsbody = skphysicsbody(circleofradius: 20) revolutionbar.physicsbody?.affectedbygravity = false self.addchild(revolutionbar)

what should add want achieved?

assuming trying achieve fire off function after passing line, first setting skspritenode have categorybitmask , collisionbitmask.

next write didbegincontact function in swift file , handle conditions checks right nodes trigger event.

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.
