fileReader for 10 marks
Dec 13th, 2006, 9:34pm  
We just had an in lab test today :p for 10% of our overall subject marks.

we had 2hrs to make a sceneload system.

**Text file***(file starts from 800, 800)***

800, 800
layer 1
rect
f 0, 255, 0, 128
s 0, 0, 0
400, 400, 600, 600
rect
f 255, 0, 0, 128
s 0, 0, 0
400, 400, 200, 200
layer 2
rect
f 255, 0, 0, 128
s 0, 0, 0
400, 400, 400, 400
ellipse
f 0, 255, 255, 255
s 0, 0, 0
400, 400, 100, 200
