Ancherpoint and position

i don’t understand why changeing the anchor point changes the look of an ui element but it doesn’t change the position i t confuses me

The anchor point functions similarly to a pivot point. The anchor point is placed on the exact position that the element has. Normally it’s in the top left, which means the element extends to the right and down.

I can set the pivot point at 0,0,0. If I change where the pivot point is in relation to the object, I can align the object in different ways, but the pivot point is at the same position.

Also, when you resize a UI element, it resizes away from the anchorpoint. So if you need to resize to the right, set your anchorpoint to the left (x=0). Vice versa you can set it to x=1.
