Object Doesn't get removed (again)

Games
#1

Now another object doesn’t remove, it stays on screen.
Even before removal print says what weapon is nil, but it is still on screen.

Example of my code:

function a()
  local weapon = display.newImageRect(...)
  ...
end

function b()
  print(weapon)
  display.remove( weapon )
end
#2

It’s a scope thing. You defined weapon in a() which prevents it being called from b(). You can either:

local weapon

function a()
    weapon = display.newImageRect(...)
end

function b()
    display.remove(weapon)
end

OR

function a()
   weapon = display.newImageRect(...)
end

function b()
    display.remove(weapon)
end

Scope tutorial for more information.

Thanks, now I understand why sometimes people use just local object

And how do I remove particles (emitters)?

ok, nevermind I removed it with display.remove()
