How to check if frames are touching

Help and Feedback Scripting Support
#1

Hi,
I need a function that would check if a frame is touching another frame and return true if so. One frame is a pin (I’m doing a lockpicking system) and the other one is a centre line. Both are sized and positioned using Scale not Offset.

I got this function from one nice person but it doesn’t seem to work, it throws an error about comparing UDim2 > UDim2.

function:

local function isLockTouchingCenter(lock)
	local lockPos, lockSize = lock.Position, lock.Size
	local centerPos, centerSize = centerLine.Position, centerLine.Size

	if lockPos + lockSize > centerPos and lockPos < centerPos + centerSize then
		return true -- lock is touching the center line
	end
end

You’d have to use the AbsoluteSize and AbsolutePosition properties, note that this does not take into account or anchorpoints or rotation but this should give you a basic idea since PlayerGuis have a :GetGuiObjectsAtPosition method:

local function getTouchingFrames(frame)
    local corners = { 
        frame.AbsolutePosition
        frame.AbsolutePosition + Vector2.new(0, frame.AbsoluteSize.Y)
        frame.AbsolutePosition + Vector2.new(0, frame.AbsoluteSize.Y);
        frame.AbsolutePosition + frame.AbsoluteSize;
    }
    local touching = {}
    for i,position in ipairs(corners) do
        local guiObjects = playerGui:GetGuiObjectsAtPosition(position)
        for i,object in ipairs(guiObjects) do
            if object ~= frame then
                table.insert(touching,object)
            end
        end
    end
    return touching
end

Thank you for helping, I’ve already done it another way and it works just fine.
