Oh.. on a second try i passed this step.
The error 'improper store' is because a mistake in given line of code:
ogl drawString: frames printString, ' frames: ', (framesPerSec
truncateTo: 0.1), ' fps'
at: 0...@font hei...@0 font: font color: Color black.
should be:
ogl drawString: frames printString, ' frames: ', (framesPerSec
truncateTo: 0.1) asString , ' fps'
at: 0...@font hei...@0 font: font color: Color black.
but then there some other errors in #uploadFont: method.
i just commented out a #flipvertically send
and two lines with 'Smalltalk isLittleEndian' ...
since its not important..
after that last fix it was able to run w/o errors, showing a swirling
red rectangle.
Here's a hacked uploadfont method.
uploadFont: aFont
| glFontID form |
glFontID := glx glGenLists: 256.
0 to: 255 do:[:i|
form := aFont characterFormAt: (i asCharacter).
" form flipVertically.
Smalltalk isLittleEndian ifTrue: [self swapBytesOf: form bits]."
glx glNewList: glFontID+i with: GLCompile.
glx glBitmap: form width
with: form height
with: 0
with: 0
with: form width
with: 0
with: form bits.
glx glEndList.
" form flipVertically.
Smalltalk isLittleEndian ifTrue: [self swapBytesOf: form bits]."
].
^glFontID
(btw, its a complete waste of CPU cycles to flip the form.
It can be flipped by a simple
glScalef(1.0, -1.0)
of a texture coordinate matrix, or use a different texture coordinates :)
So, a texture's up will become down and vise versa :)
