can some 1 help me to learn how to make loading page?

PLS PLS TELL ME HOW i beg of you idk how if u say how ill be happy :)

Firstly, you should know this isn't a request site and people will not make scripts out of thin air for you, you need to have done an attempt yourself.

Secondly, you can find out how to make a basic loading screen here.

I hope my answer helps you. If it did, be sure to accept it.

Well, too add on to Spongcardo's answer, you can make another in-game loading screen here. It's not much of a loading screen but you can use this to load pictures, sounds, decals, etc. This is good if you have a well detailed game because sometimes when you play it, there are no textures, decals, etc. So loading is always a good thing :3 This might be better than the basic loading screen because the basic loading screen loads and prepares the game for you to join. It doesn't help load instances and stuff.

Hope it helps!
