Rubygame -- need help with zoom

[Bryan Richardson]

Hello all,

I'm trying to get a Rubygame example to zoom, and can't seem to do so.
Right now, I'm simply drawing a single pixel at the center of the
screen, then trying to zoom when I press the space bar. I have my event
queue set up right, because if I tell it to print something when the
space bar is pressed it works. Here's how I'm trying to zoom:

@screen.zoom_to(@screen.w / 2, @screen.h / 2) if event.key ==
Rubygame::K_SPACE
@screen.update

Anyone know why this isn't working? The pixel at the center of the
screen stays the same size...

is a 1pixel x 1pixel object fixed at that size, ignoring scale?
have you tried drawing a box or translating it?

Ah... good point. I'll try that.

Hi Again David,

So I drew a polygon using the code below, but the screen still doesn't
zoom...

@screen.draw_polygon([ [10,10], [200,10], [200,200], [10,200], [10,10]
], [255,11,147])


Am I still missing something?
