You want to make a super smash bros game using game maker but you dont know were to get a engine or what code you need to use and It cant have any glitches?

Answer 1

I'm improving this answer for you, since the other one is not sufficient to fully answer the question. I have left the YouTube link as a resource.

A game like Super Smash Brothers is very complex in design and takes more than a simple engine to craft due to all of the unique content that usually comes with these kinds of games. If you feel that you are ready to make a game, you could learn GML if you dedicate about three days on its FAQ and some online GML guides. It is very easy to do if you read through and experiment before diving in. Three days is a small price to pay for gaining pretty much complete knowledge of the language.

Some of the commands you will find yourself using include place_free(), for loops, keyboard_pressed() or released() or press(), etc. All of these commands are easily at your disposal. Just give yourself three days to learn it all.

Youtube provides some good tutorials, but listening to very experienced Game Maker creators, such as Cactus (did an excellent presentation on quickly-made games), will give you insight on good game design.

A game only takes time to make because you have to learn how to do it first. Once you do, every thing is just a puzzle, and you have all of the pieces.

One of the better engines that have been getting praise, recently is called zPlat, an extension of _Player_'s glitch-lacking platform engine, and you can grab the edges of platforms and pull yourself up like in Commander Keen. You should easily find it in 64Digits.
