Before I say anything, the most important rule of this section is to make sure you're not making something that's already been made. For example, Mario is already in the game so nobody should make an assist trophy or a trophy of him.
This is the other work section, where all the work goes for the ssb4 game that isn't for the characters.
For example, items, pokemon, assist trophy people, stages, trophies and more.
I'm the leader of this section.
Now, down to business.
Stages are easy enough, make a stage that's big enough to have a fight on.
Assist trophies are harder so I found a tutorial.
This is NOT made by me.
Here's the sprite sheet you use to make them.
For pokemon, it's pretty much the same thing except with different sprites.
Here are the pokeball sprites.
Remember, to make pokemon, follow the assist trophy tutorial.
The pokemon and assist trophies must have a description of what they do.
For items, just sprite or find them and we'll see what I think.
For trophies, the trophy stand is here, just put whatever sprite you want on it.
These are not character trophies though because the person who's making the character can make those.
These are just regular trophies that you can unlock.
Here's the trophy stand.
Credit to SSF2 for the trophy stand.
The trophies have to have an explanation of the character.
Bosses are like assist trophies.
You need a lot of animations for attacks and stuff but not as much as for a character.
Enemies are pretty simple.
You make an animations for it moving around, at least 1 attack, a stance, a dying animation and maybe some other stuff.
You have to claim your character at it's appropriate list before you start.
Everything has to be accepted by me so don't think you can make any random crap and it'll be in the game.
When your work is accepted, it will say (accepted) beside the title of the topic.
You MUST put what it is before the title.
So, for example, if I was going to make an assist trophy of krillin, I would put in the title: Assist Trophy: Krillin.VERY IMPORTANT RULE: Everything you make must have a trophy and a trophy description.
If you still don't get it, look at some of my stuff.
That's about it, make stuff to your hearts content.
Have a good time!
