Mojo2 crashes in Glfw3/Mac when setting font

Monkey Forums/Monkey Bug Reports/Mojo2 crashes in Glfw3/Mac when setting font

Provided that the font.png file is in the correct place, this code works in html5, but causes a memory violation in Glfw3 on a Mac (El Capitan, up to date Xcode).

[monkeycode]

Import mojo2

Function Main()
New Test
End

Class Test Extends App

Field font := Font.Load( "images/font.png", 32, 96, True )
Field canvas :Canvas

Method OnCreate()
SetUpdateRate( 30 )
canvas = New Canvas
End

Method OnRender()
canvas.Clear()
canvas.SetFont( font )
canvas.DrawText( "Test 0123456789 abcdefghijklmnopqrstuvwxyz", 20, 20 )
canvas.Flush()
End

End
[/monkeycode]

Never mind, just found out that loading the font inside OnCreate() works.
Took me a while to figure it out... this will work:

[monkeycode]
Import mojo2

Function Main()
New Test
End

Class Test Extends App

Field font :Font
Field canvas :Canvas

Method OnCreate()
SetUpdateRate( 30 )
canvas = New Canvas
font = Font.Load( "images/font.png", 32, 96, True )
End

Method OnRender()
canvas.Clear()
canvas.SetFont( font )
canvas.DrawText( "Test 0123456789 abcdefghijklmnopqrstuvwxyz", 20, 20 )
canvas.Flush()
End

End
[/monkeycode]

k.o.g.

I think it's not a bug. In Monkey, you have always to load graphic and sound stuff after initialization, eg: OnCreate :)

I don't find currently the text about this behavior in the Documentation sorry, but it's true :D

Yeah, I tend to initialize things as I declare them, forgot about loading only inside OnCreate. Will remember next time.
Thanks!
