Ok. I will make as you say. First of all as far as I know there is no Naruto singleplayer maps. I'd like to make something original and easy in the same time, because I'm just a beginner. So this was the perfect idea.
Being a single player doesn't make it authentic.
I think I can do a good terrain thanx to the cool tutorials from this site... Anyway it will be better then it Naruto Ultimate RPG. It won't be hard at all because there are very good images in the anime and I can make them easily.
Reading the tutorial would not be enough, you need to practice it as well.
The biggest chalange for me are the triggers. They aren't hard at all if you know how to do them, but the problem is I don't really know all the triks. So I will need some help at the triggers.
Read the tutorial and try to make it yourself to understood what need to be done.
I will ad some cool sistems you guys made. I've found some very good inventory sistems and I will use one of them. This will make my map unique as the first Naruto map whit inventory sistem.
Having an inventory system doesn't make it any good. The term of unique are varied to everything and not just limited to 1 inventory system.
I'd like to make an ability sistem where you can upgrade your spells.
If you mean by increasing the damage, it would be a waste of time considering that each time a hero level up. They would earn a point to level up their spell, which gradually increase the power and effectiveness of the spell.
If I make a spellbook, I can't change the level of abilityes separatly.
You can add all spell into 1 spell book and set it as hero ability, but if you want to make the ability level separate. That would be a case nobody could solve.
In the end my third problems are the spells.
Our spell section have what you want, go do a research.
From what I seen, I do not think you ever finish reading the tutorial written by me. Your project are going to fail from my aspect of view, even if you manage to finish it. It would be a rather poor quality work.
I would give you 3 reason why it won't success.
1) This is your first project and you are new to WE; even if you have determination, you lack of the basic skill require in mapping.
2) Your first project is campaign, campaign is the hardest generic map to be accomplish compare to other genre (I do not kid you, I am making a campaign and I know how hard it was).
3) Instead of learning how to make a basic generic map such as melee map, you jump right ahead into a tough genre (Campaign) without any proper practice. This is equalvailent to trying to swim when you do not even learn how to walk yet.
Read this tutorial of mine again and try to understand it, not try to glance at it.

90% of the Naruto map are complete failure and useless, only a few are outstanding and excellent. If you still insists of making the campaign, go ahead but you would make yourself a laughning stock if you do not make a proper planning for it.
My suggestion for now is to learn the basic. Do not drown yourself.
