This is a bizarre error that I don't understand.

Create the following class and save in a module, eg "test.monkey" in a new module folder "test".

Import mojo

Class TestClass

Method Draw:Void()

SetAlpha(0.5)
SetColor(255,32,32)
DrawText "25",200,200,0.5,0.5
SetColor(255,255,255)
SetAlpha(1)

End Method
End Class

In the main module that your program runs from have the following:

Import mojo
Import test

Function Main()
Local myapp:MyApp
myapp = New MyApp

End Function 

Class MyApp Extends App

Method OnCreate()
SetUpdateRate 30

End Method

Method OnRender()

Cls
Local test:TestClass
test = New TestClass
test.Draw

End Method
End Class

Ok..I'm using Firefox 3.5.7.
When I run within monk, it runs fine.
When I run from the web it runs fine (see here:

http://home.swiftdsl.com.au/%7Etmalcolm/error_monkey/

)

However, if run it from my local machine in the build folder, or any other folder on my machine I get an "NS_SECURITY_DOM error "1000"".

If I remove the DrawText command then it runs fine.

I only noticed this when I tried to run one of my games from my local machine instead of from the web....

Strange bug. Although I'm guessing it is something more to do with the browser than monkey.

It is a 'security' problem on Firefox - or a bug of FF if you prefer.
To avoid this Mark introduced Mserver.exe to play locally HTML5 contents from MonkIDE.

This isn't really a bug on Monkey or FF's end. When calling DrawText, it tries to access mojo_font.png, which is included in the data folder. Since you're trying to load the HTML file directly, the browser's javascript engine is (correctly) blocking access to the data directory. Something to do with domains or referrers or something I think.

With one of the recent patches, Mark added MServer (a tiny web server) to host and test HTML5 builds. (degac beat me to it...)

So it's the same as Flash, except that Flash gives you a fix to okay some of your own folders for use with Flash (that little online applet we have to run before we can target Flash)?
