Global Var MenuSelect

Global Var MenuSelectPx

Global Var GoSelect

Create Object MenuSelect as Bar Color (Opacity 40 (Ex))

Start Layout MenuSelect = 1 (A)

MenuSelectPx = Inicial Pos Y Menu A (Ex: 400)

A=1 <- Selected MenuSelect Bar Color - Pos Y of A(Ex: 400)

B=2

C=3

D=4

E=5

F=6

Distance between menu texts (ex: 40 px)

Gamepad:

On Game Pad DPad Down MenuSelect = Min(6,MenuSelect + 1)

On Game Pad DPad Up MenuSelect = Max(1,MenuSelect - 1)

Mouse:

On mouse over A - MenuSelect = 1

On mouse over b - MenuSelect = 2

Etc...

Every Tick: MenuSelect "<-(bar color)" lerp(Self.y,MenuSelectPx+(MenuSelect*40),10*dt)

Or

Event: MenuSelect <> 0 and trigger once

MenuSelect (Bar Color) Destroy

Create Object MenuSelect (Bar Color) Pos X (ex: 1100) Pos Y MenuSelectPx+(MenuSelect*40)

On click:

GamePad Button A - GoSelect = 1

On Mouse click - GoSelect = 1

Event: System Global GoSelect = 1

SubEvent - MenuSelect = 1 Goto Layout x

SubEvent - MenuSelect = 2 Goto Layout y

SubEvent - MenuSelect = 3 Goto Layout z

SubEvent - etc...

I think this is it.
