I'm having some issues when attempting to show my project in full-screen mode. Here's a screen shot, with the graphical artifacts or "dithering" shown (click the image to view it full-size):
Game resolution is 640x480, game is shown in full-screen mode on a flat panel monitor.
Anyone else notice this on their projects? Any idea on what causes them, or--better yet--how to eliminate them?
I m having a 20" wide screen and it doesn't support 4:3 scaling, so I ussually set Maximized on boot up. That helps, but the resolution remains the same, it doesn't go fullscreen, but it does stretch the black color around the screen.
As far as I've heard, this kind of thing occurs thanks to the use of the built-in fadeout transition. Specifically, the one called "Fade Out." If you use that, it causes all sorts of "leftovers" to hang about on the screen.
A workaround to this issue is to adjust the object's Transparency instead of using the built-in transitions. I plan on putting together a brief article to explain some coding for this, but here's a summary.
--set aside an Alterable Value for the object you want to fade out; label it something like "trans value."
--Create an "Always" event that links the objects Transparency to this Alterable Value.
--Create an "Always event that indicates when the object is visible, add 1 (or some other positive integer) to the Alterable Value.
--Set an event that destroys the object once the Alterable Value reaches 128 or higher.
An article is forthcoming, useful in assisting newbies like myself.
Without slapping a huge technical reason for why this appears to be happening... it looks quite frankly, like you're trying to resize an image vertically without adjusting it appropriately horizontally. Just like how if you stretch an image too far in one axis and you get pixels that are bulky and ugly, you have lines of pixels here that are unusually thin.
I doubt you have any real hardware issues, monitor issues, software issues, none of that stuff. You're simply stretching the image wrong. Turn your stretch settings off and/or adjust the resolution of the game and I'm sure the problem will disappear.
