Cave Story Versus?

Is it possible to make a mod were multiple players can verse each other? I think it would actually be fun with boosters and missiles going at each other. Even a mode where other players have to capture the flag or something. I'm no programmer or let alone know how to use the mod tools on this site, but I think it would be a great idea.

 

It's not possible to "verse" other people, but they can definitely "face against" each other, if you know what I mean. That aside, as far as I'm concerned, there's no possible way to incorporate multiplayer with modding alone. I don't know if assembly hacking changes any of that, though.

thank you

In any case while /technically/ this would be possible, it's nowhere near worth the astronomical amount of effort you'd need to put in.

 

Or just do what sonicfandude1 did on YouTube when he tried to make his own Cave Story 2 (before cancelling it) by making a new engine entirely from scratch with Multiplayer incorporated. (Don't know how he did that, considering he didn't reveal any of the software he used.)
Or you could just use M.U.G.E.N.

 

Cave story versus Ikachan.

 

The premise seems fun though... A quick matchmaking setup where forum members and other fans could battle it out (would have to edit the values and likely the mercy invincibility...)

Yah.. Not worthwhile in the original exe, but possible with one's own engine. It's also been started multiple times, but none have made it through.

 

Nobody.
No one ever.
It's been attempted at least 3 times and Cave Story isn't getting any younger. The truth is that Cave Story is poorly designed for PvP, so you'd either end up with a shitty game or one that barely resembles Cave Story. You might as well play Gang Garrison 2.

 

uhhhhhhhh it should be in defines.txt ... which you replace the existing defines.txt or whatever with

freebie function, computes the distance between two points
PUSH P2Y
PUSH P2X
PUSH P1Y
PUSH P1X
CALL <function>
ADD ESP, 10
length rounded to the nearest integer returned in eax

Then tell me what this is.

 

, computes the distance between two points

it says right on it

 

it says right on it

But why would you make it if you weren't going to use it for *something*.

and the P1X (Player 1 X positon) P1Y ect has me suspicious.

and you mentioning two player Cave Story in one of your modding videos.



I know your going to pass this off as "I was using it for something else", but only time will tell.

Then... then we shall know the truth.

 

Bombchu you do know that you need two points to compute distance between two points, right
First point = A(X1, Y1)
Second point = B(X2, Y2)

 

It's Point1X, not Player1X

 

I'm pretty sure if I ever mentioned it, it would be to say that it is beyond impossible
and computing the distance between points is just a useful thing in general

 

When they say it's impossible, we just accept that as a challenge.

E: but I know that you wouldn't make the function if you weren't going to use it for something.

 

No.
Cave Story is not fit for multiplayer in its vanilla state. It is a story driven game that would not be compatible with the addition of a second character.

 

Yeah, Cave Story isn't really made to do anything but be Cave Story.

 

I dunno, I mean
It's pretty damn moddable

 

I dunno, I mean
It's pretty damn moddable

I meant by crazy ASM hacks and implementing *new* features.


It's suppose to be a side scrolling Shooter, Period.

the only mod that I can think of that came close, is Randolf's space mod.

Without stuff like the source code, it's just not going to happen.

 

What are you even trying to argue anymore

 

...Actually I have no idea at this point.
