Even the most people get sick of hearing this... Its the best and easiest way to get better
Keep playing
The only way to master any fighting game is to play it over and over, win OR LOSS. To level up your game, you are going to need training mode, and i mean literally hours, just to know exactly what can combo off of what, and this goes for all fighter man. Plus, these forums have lots of information, so try to learn as much about a character as possible. If you keep dropping combos against another person, practice that combo in training, and better yet put the CPU on so you arent just punching the dummy to death. Now that I got through the intro, lets go in depth
How to get good at fighting games
1. Learn you character
In fighters, most people end up using,(maining) at least 1~2 characters, or even more. I suggest picking one character to start with and try to see how well your game develops. After you pick that 1 character, search the internet for info on that character, and there are 2 main sites for fighters(well more, but these two are the most popular):
Shoryuken.com- Street fighter series, some blazblue, Tekken series, Marvel series, V.S series
Dustloop.com- In-depth material on Blazblue series and guilty gear
Go to either site and look up info. You'll learn that characters in games have certain things that make that character special, for example, I wanted to main Carl Clover. He is good at resets and, well, yeah. So what is the next thing you do after you find info about a certain character you want to main? Well, you always want to know the characters Anti-Airs(AAs), Bread-and-Butter combos[bnBs] (simple combos to get a match started, or to use in any match), and match-ups( what you should be focusing on in a match when fighting against certain characters). When you figure out these things go on to step two.
2. Train
Once you have info on a character, hit training mode. Practice combos, BnBs, and see what move combos off of which. When you feel "confident" try to put the CPU on max difficulty(most fighters have this option available) and try all the new things you learned. Now dont be discouraged if you cant do everything on a maxed level Ai opponent, because people will not be able to read every input and counter you, but wait, what if you could do that?
3.Ask around/ seek more info
remember when I brought up match-ups, well they came back to haunt you. Most forums have a match-up thread where all characters have some method of dealing with other characters. These methods were discovered by posters like myself and in the future, you. For example, in general, if you had a character who was good at zoning( or spacing, pushing an opponent to control the stage or fighting space) and a character who is better as a rush down( not letting the opponent get a chance to retaliate by applying a tactic known as a pressure game, or just pressure), how do you think the match would go? Would the zoning character just let the rush down character attack? Hopefully not(but some people will). Its Your job to find ways to expose your opponents weaknesses during any match. However, some people have the ability to use their weaknesses against you, or better yet, make it difficult in finding their weakness. :8/: (what, how?) well, because they looked up information. They can predict exactly what you are going to do next( called reading your opponent) How did they read you? They know about your character, and they use your weaknessese against you.
*this is probably the weirdest number here, i can clarify to you directly, but I think another poster can help you.
4. Get friends
So you did steps 1-3, now you want to play with people. Well, playing online with random people is fun, but not as fun as playing with a friend. You already have a beastly friend but they seem as if they don't want to tutor your ass, so i suggest finding somebody who is also looking to get better at fighters, or some fighting vets who are willing to help. Having friends is a fun and good way to get better at any fighter
Im going to stop here, but I hoped I helped you with some info.
Good luck, and fighters are not easy to master (most) they take patience, and work, just like everything else in life. But the more effort you put in, the easier to get better.
