So, uhm, I'm having a problem, and I feel that it's pretty serious.
I was attempting to do window scaling for my pixel game. I wanted to give the user the option to play in a regular window(320x320) or a doubled window(640x640), for those who like to see everything at 2x size. However, no matter how many times I tried, my results turned out blurry as heck. It seemed that regardless of whether I chose point sampling or linear sampling, I had the same results. I had thought that what I was trying to do was a very simple thing. I was just setting the client height and width to double what they already were.
So, in effort to solve my problem, I checked this post. The first thing I did was take a look at the Megaman example provided. However, when I opened it, and tried the enlarged settings, they looked blurry as well. At this point, I became quite confused.
It seems to me that point sampling does not work on my computer or something. To me, linear and point sampling look exactly the same, regardless of whether I'm viewing my .cap or the one provided in this post. Point sampling appears blurry, just as linear.
I consulted the IRC channel, and someone using a dual monitor set up tried my .cap. According to him, when he moved the window to one screen, point sampling worked. However, when he moved the window to his opposite screen, it no longer worked(as if one screen was using point and the other was using linear). This, to me, was even more confusing.
My conclusion is just that point sampling is broken.
Here, is a screencap of a tile scaled to double size in paint(right), and one scaled to double size using point sampling in construct(left). As you can see, point sampling is blurry.
And lastly, here is the .cap of my project, set to point sampling. On my screen it appears blurry when the client is doubled(press Z). But, on your screen, it may appear correct, I really am not sure.
(Note that in order to downlaod the .cap on that page, you must scroll to the bottom and find "click here." Otherwise, you'll end up downloading a toolbar, or a robot dancing to Miley Cirus.)
If any additional details or screencaps are needed, please let me know.
Thanks in advance.
