How would I work with Gui Collision?
A user controls a frame with arrow keys and moves it around, I don't know where to start when making it so if the frame called Pixel touches other frames called Border or Block it will not allow them to move past that frame or move into it. How would I completely disable movement in the direction they are going when the pixel frame touches another frame?
How would I use Gui Collision? How do I use it? What methods should I use?
I just want a better understanding and what I need to do to apply it with what I am doing.

Here's a function to check for GUI collision. You call it like this:
if isColliding(enemy, player) then --blah end
function isColliding(body1, body2)
local b1x = body1.Position.X.Scale + body1.Position.X.Offset
local b1y = body1.Position.Y.Scale + body1.Position.Y.Offset
local b1sx = body1.Size.X.Scale + body1.Size.X.Offset
local b1sy = body1.Size.Y.Scale + body1.Size.Y.Offset
local b2x = body2.Position.X.Scale + body2.Position.X.Offset
local b2y = body2.Position.Y.Scale + body2.Position.Y.Offset
local b2sx = body2.Size.X.Scale + body2.Size.X.Offset
local b2sy = body2.Size.Y.Scale + body2.Size.Y.Offset
return (
b1x + b1sx > b2x and
b1x < b2x + b2sx and
b1y + b1sy > b2y and
b1y < b2y + b2sy
)
end
GUI collision is actually really simple once you wrap your head around it. It's just simple comparisons using > and <. If you want an in-depth explanation, just ask.
