Destroying listeners

[einarnordengren]

Is there any way to destroy contact listeners or destruction listeners? It looks like the references to them are destroyed in the world's Destroy() function, but the number of LuaRefs keeps increasing every time I reinitalize the world.

If you set nil, Listener should be destroyed

defold-box2d/box2d/native/src/world.cpp

if(world->destructionListener != NULL){

I look at code. It looks like listeners removed when world is destroyed.

defold-box2d/box2d/native/src/world.cpp

Line 736 in bb6ca23

if(contactListener != NULL){

Right, so it should work by just destroying the world. However, if I add

self.world:SetContactListener({
    BeginContact = function() end,
    EndContact = function() end,
    PreSolve = function() end,
    PostSolve = function() end
})

in the init function of the dominos_scene.script, the number LuaRefs increases (checked in the web profiler) every time I press restart even if the world is destroyed in final.
