vertical drag

[Riraito]

how would I go about making it so when you drag a frame, it only moves vertically?

Have an anchor and offset tag in your frame that is relative to UIParent

On the event OnReceiveDrag check if the offset x value has changed then reset it.

Might work i'm not 100% on how dragging works.

If OnReceiveDrag doesn't work use On_Update but start your checking flag in OnDragStart
