Lua Box2d Gideros: Hide bodies

Question

In Gideros studio box2d, bodies(which are basicly the physical object, not the picture that goes with it) always show up as a translucent shape. In my game, i don't want players to be able to see these bodies. I've seen that you can do this in corona, but I haven't seen anything about Gideros. Is there anyone who knows lua and box2d well enough to tell me how to do this? Thanks!

Thanks! I was editing an example that I downloaded, and I didn't see that part of the code. — Henry V, Sep 28 '14 at 13:07

If it is really debug drawing, then click on top menu Edit, choose Find in files and search for DebugDraw

You should find something like:

local world = b2.World.new(0, 10, true)
local debugDraw = b2.DebugDraw.new()
world:setDebugDraw(debugDraw)
stage:addChild(debugDraw)

Just comment out the line --stage:addChild(debugDraw) and you are good to go. Remove setting debug draw completely for production for better performance

You can setup some global variable debug and toggle it to enable/disable debug drawing:

DEBUG = false

and then later in your code

if DEBUG then
    local world = b2.World.new(0, 10, true)
    local debugDraw = b2.DebugDraw.new()
    world:setDebugDraw(debugDraw)
    stage:addChild(debugDraw)
end
