Simulator crash when using director class with physics

Director Class
#1

I am having trouble using the director class when using the physics API. I have made a small example below. As soon as I add the physics.addBody line the simulator will crash. The code below is loaded by a director:changeScene in another module that also loads the physics package.

What I am doing wrong here?

Thanks
Thomas

module(…, package.seeall)

local gameGroup

function new()
gameGroup = display.newGroup()
local background = display.newRect(0,0,display.contentWidth,display.contentHeight*2)
background:setFillColor(255,255,255)
gameGroup:insert(background)

local bottomEdge = display.newRect(0,display.contentHeight*2,display.contentWidth, 10)
bottomEdge:setFillColor(255,0,0)
physics.addBody(bottomEdge, { density = 1.0, friction = 0.3, bounce = 0.2 } )
gameGroup:insert(bottomEdge)

return gameGroup

The physics module will only work if you require it at main.lua file once or if you require it individually at all the files you want to use it. [import]uid: 8556 topic_id: 6140 reply_id: 21141[/import]

Hi Ricardo,

I have already included it in the main file. You can see the main file and the file that is called below. It is a really short example but enough to generate the problem. When I have the physics.addBody line there the simulator just crashes. If I delete the physics.addBody it runs ok and shows a white background.

Do you know what is going wrong?
Best,
Thomas

[code]
– main.lua
display.setStatusBar( display.HiddenStatusBar ) --Hide status bar from the beginning

– Import director class
local director = require(“director”)
local physics = require(“physics”)
local gameUI = require(“gameUI”)

– Create a main group
local mainGroup = display.newGroup()

– Main function
local function main()

– Add the group from director class
mainGroup:insert(director.directorView)

director:changeScene( “level3” )

return true
end

– Begin
main()

– level3.lua
module(…, package.seeall)

local gameGroup

function new()
gameGroup = display.newGroup()
local background = display.newRect(0,0,display.contentWidth,display.contentHeight*2)
background:setFillColor(255,255,255)
gameGroup:insert(background)

local bottomEdge = display.newRect(0,display.contentHeight*2,display.contentWidth, 10)
bottomEdge:setFillColor(255,0,0)
physics.addBody(bottomEdge, “static”)
gameGroup:insert(bottomEdge)

return gameGroup

You forgot to start the physics engine, please take a look at the link below to read some really useful information about it.

physics.start()

Ahh… thanks! That helped a bunch. Sorry, but I am completely new to this, but having great fun trying it out.

No problem, if you learned how to use it then it’s what matters! [import]uid: 8556 topic_id: 6140 reply_id: 21487[/import]
