Furry Player When Screen is Not Scrolling

[Frostt]

Hey all,

I'm trying to fix a problem I came across with the clarity of RMXP's graphics, but I am not sure what is causing the issue.

With a default new project in RMXP, when the player moves around on a small map where the screen does not have to scroll with the player to show more of the map, the framerate looks choppy and the player appears to be blurry.  But when the map is big and the screen scrolls as the player moves, the player appears perfectly clear.

Does anyone know what causes this, and how it can be fixed?  Does it have something to do with the way RMXP refreshes when the screen is not scrolling?

I'm drawing a blank here.  I'd appreciate any help!

Bump.

Has anyone ever noticed this problem?

Thanks again.

I didn't notice it until you brought it up.

I think it's just the fact that the character animation is only 4 frames, and when the map is moving the character is stationary in the center of the screen, so it looks clearer.
You can improve it by setting the frame rate (F1 -> smooth scrolling, reduce screen flicker).
I think the only other way to improve it would be to increase the number of frames used for animation. (script)

Be Well

It starts scrolling the screen earlier and stops later when you reach the edge, so the fuzzy look to the player isn't so bad.  I need to use it in all my games because my eyes are so bad, and Reduce Screen Flicker doesn't help me.

... or you can press F1 while playtesting a game and make sure that all 4 checkboxes (in particuliar the Smooth Scrolling and the one with your CPU name in it)

That improves the framerate a lot ^_^
