Re: coordinates problem
1) when you move the mouse cursor around in the window, you can see its x and y coords in the bottom.
2) you can drag a sprite to where you want it, and then switch to Motion blocks and the different blocks will automatically show up with that sprite's x and y in the selection windows. If you are already viewing the Motion blocks, just click on any of the other blocks (Control, Looks, etc) and then click right back and the current values will load.
aka Pain from DragonSpires, Delrith Online, BotBattle, Urban Dead etc etc lol

Re: coordinates problem
The costume center might be off. Go into the paint editor, and look in the lower-left corner. Click the button that looks like a crosshair, and drag it to the centre of the image. That's the most common problem.
I'm taking a break from Scratch until 2.0 comes out. Any messages sent between then and now probably won't be read - sorry.

Remember that (0, 0) is the exact centre of the project - you might be under the impression that it's the upper left corner.
Other than that, I can't entirely help you unless you upload your project.
Wait if 0,0 is the center, and the screen is 480 x 360, then would the corners be:
(-240, 180), (-240, -180), (240, 180), (240, -180)?

Re: coordinates problem
Is that the limit of the screen though? Isn't there a small space around it? How much is the extra space added together with the 480x360 screen? And also for sprites, the center that you set on them; does that point go to the xy point on the screen when you put 'glide to x, y' ? Is there some kind of grid thing that you can activate on the paint editor?

You mean that shadow? That's actually on the screen.

Are you referring to that when the sprite goes off the screen, it will never fully exit?
Yes, I've found this to be a problem. There's 8 pixels on either end, I think, that will always stay on the screen, unless the sprite is less than 8 pixels.

Re: coordinates problem
So that's... 496 by 376 without being compressed. I've seen a project where the background has been enlarged a lot of times, and it goes off the screen. Where exactly does that extra part of it go? It's certainly bigger than 8 pixels.
Can you set a pixel as the center of a sprite or is it always the corner of a pixel?

The pixel can be the center of the sprite.
You can still use the 8 pixels on all 4 sides, it's just that the 8 pixels might get filled up when a sprite tries to leave the stage. In reality, it truly is 480 by 360.
