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.
