Keeping size no matter screen resolution?

So in my shop, I am trying to keep the same size, and when looking up how to keep the same aspect ratio, it changes the size and squishes all my items into a small space. But in Assassin, if you do that, it keeps its size.

Hope someone can answer my question! Thank You!

Hey KingStared,

The reason why you keep encountering this 'problem' is because in Assassin the Size of the Guis is done by Offset however, the Position is done in Scale. Which is why, the Gui changes it's position when you resize the window however, it's size stays the same. For you to change your Gui's Size to Offset is quite simple.

Guis have Size and Position and these are UDim2 values. UDim2 values have 4 parameters in total. 2 of the first ones being 'X' and 'Y' and inside 'X' and 'Y' are 2 more properties: Scale and Offset. When you change the Scale of a Gui, that means that no matter how big or small the window becomes, the Gui will adjust accordingly however, with Offset the Gui keeps it's original coordinates and will not change it's Property no matter if you resize the window or not. So, you just have to change the Size properties of your Gui from Scale to Offset. By the way, I made a Java program a while back that changed Offset to Scale and vice-versa. I'll give you the equation to change from Scale to Offset.

####For X Coordinate Changing of Scale to Offset

local max_pixels = 1439; -- The max amount of pixels. For me it's 1439 idk what it is for you might be the same but, I think it changes for each screen. Check yours by simply extending a Part's Size all the way and see when the opposite end of the Gui leaves the screen and that's how you find the max amount of pixels in the X coordinate.

local scale = -- This is the scale of the X coordinate of the Gui that you currently have.

local pixels = scale * max_pixels; -- This is the amount of pixels that your scale is. Just substitute this into your Gui's Size and erase the Scale of the X coordinate.

print(pixels)

####For Y Coordinate Changing of Scale to Offset

local max_pixels = 610; -- The max amount of pixels in the Y coordinate. For me it's 610, might be different for you.

local scale = -- The scale of the Y coordinate of the Gui that you currently have.

local pixels = scale * max_pixels;  -- Yea, the formula is pretty much the same but, the maximum pixels for the Y coordinate on my screen is different then the X so I had to make 2 different functions to figure them out. Idk what yours is but, just substitute my max_pixels for yours.

print(pixels);

##Well, I hope i helped and make sure you only change ur Size from Scale to Pixels and not your Position. Also, delete the Scale coordinate once you are done converting and you've set the Offset property accordingly.
