No error but window doesnt show

[frostways]

Hi, I'm trying to build a game, I'm completely new to this... and I don't know how to structure a code...
I've those tree codes
This one which juste defines window :

package auxiliaire 

import (
	"github.com/faiface/pixel"
	"github.com/faiface/pixel/pixelgl"
)

//Config des fenêtres
var Dimension pixel.Rect = pixel.R(0, 0, 1400, 780) //dimenseion

var MainWindowCfg = pixelgl.WindowConfig{
	Bounds:    Dimension,
	Resizable: true,
	VSync:     true,
	Title:     "IACATS",
}

var MainWindow, _ = pixelgl.NewWindow(MainWindowCfg)
var Centre pixel.Vec = MainWindow.Bounds().Center()

This one which (in the future) run a level :

package niveaux

import (
	"jeu/auxiliaire"

	_ "github.com/faiface/pixel"
	_ "github.com/faiface/pixel/pixelgl"
	"golang.org/x/image/colornames"
)

func LaunchLvTest() {
	WindowLvTest := auxiliaire.MainWindow
	backgroundColor := colornames.Cornflowerblue
	for !WindowLvTest.Closed() {
		WindowLvTest.Clear(backgroundColor)
		WindowLvTest.Update()
	}
}

and the last one which is main :

package main

import (
	"jeu/niveaux"

	_ "github.com/faiface/pixel"
	"github.com/faiface/pixel/pixelgl"
)

func run() {
	niveaux.LaunchLvTest()
}

func main() {
	pixelgl.Run(run)
}

but it doesn't show any window just printing this in the terminal

(base) MBPdeAlexandre:jeu frostways$ go run main.go 
niveaux/niveautest.go:4:2: found packages auxiliaire (animations.go) and main (fenetres.go) in /Users/frostways/go/src/jeu/auxiliaire

I suspect this has something to do with the way you are setting up your packages. Can you show your golang env variables like $GOPATH, $GOROOT, $GO111MODULE and the paths that those files are in please?

It was just a misunderstanding of how go packages are working.
Ty fort you time <3

Yeah I'm really enjoying this library but since I'm kinda new to programming and because there is not a lot of learning ressources about pixel (and I don't know the "regular" ways to code a game) It's quite hard but I enjoy the journey by now! Fortunately I'm studying math and physics at university... It helps for modelisation understanding and having ideas :')
