Quick Modding/Hacking Answers Thread

512 is the hard limit of entities at any specific point in time, I can't remember if the function that loads entities from file starts at 0 or 256 though.

I believe nox says that there is room for either 512 entities or 256 entities, he couldn't remember. My guess is 256, so try bringing it down to that.
Do you really need 375 entities though?

I need many spikes, yes!
I guess I'd have to remove some of my area, since the spikes can't really be replaced.

 

There should be a spike tile in your tileset, if there's not then make one. They won't take up your needed entity space.
Alternatively use more than one room.

 

Sorry for the double post, but it's been like, three days and I have a question. Well, two.

I've finally broken down, and I need help.
First of all - what the heck is function 40AC90 (create animated effect) doing in 419910 (take damage function)? I tested the exe without the call to that function in it, but nothing happens.

I've also found this:

Address    Command
00419A9B  MOVSX EAX,WORD PTR DS:[49E6CC]
00419AA2  TEST EAX,EAX
00419AA4  JLE SHORT 00419AD1

From what I gather this checks if the player's current health is at or below 0 (and some overflow crap as well), and if so jumps to 419ad1, but it just seems to JMP a couple times and repeat some of the "take damage" code. I'm wondering what it thinks it's doing, because I'm trying to find the part of the code where the player dies.
Nevermind that part, found it.

I know nothing of ASM, but I would assume that would be the invincibility-flicker thing for when you take damage. You know, how you flicker in and out of existence for a short while after taking damage, being invincible during that period of time?

 

40ac90 is never called in 419910. The only calls are to playSound, runTSC, and makeSmoke. You are clearly crazy.
And you seem to have solved your other problem.

@Dunc that isn't an effect. The player simply doesn't render if he is being flickery and some other condition.

But...But...it's in the function! Before all the stack "recalibration" stuff! I swear I'm not lying!
And yeah sorta, I guess. I still need to actually bend it to my will.

 

I was looking over the commands on that website you gave me noxid, but I couldn't find the numbers for the song Starry Night.

Wouldn't that be because Starry Night isn't a song that appears in Cave Story?

 

Are you talking about Moonsong? Because that's song number 25 (or <CMU0025).

 

Well, I looked in ORGview for songs I wanted in my mod, and I found the song called starry night. I looked at the link Noxid gave me to see the number to input on CMU and it wasn't there. So that confused me since it was in the ORGview

 

@LUNARSOLD
Oh I see. olly wasn't recognizing it for whatever reason.
Yeah it appears to be the level down effect. A curiosity it is not.

 

What version of OrgView are you using? The AGTP version still says Moonsong, and I don't know any other version that says "Starry Night."

 

oops. I said the name wrong, but it's probably no different. It's called Starry SKY

 

There is no song named starry sky.
Do you remember if and where you heard it in the original CS?

 

I think he means Balcony.
Also, how would one change the title screen music?

 

oops. I said the name wrong, but it's probably no different. It's called Starry SKY

Starry sky is my org. Used in MS? Get out of there, use a fresh copy of CS.

EDIT: How do I set invincibility? I need to set it up for a 419910 hack.
Nevermind I found it.
And guess what? It was 40AC90.
The AnimatedEffect function.

No it's not, give me a minute.

 

Oh. That explains it. I must've mixed up my orgviewers. I don't know how, but lol

 

Also, how would one change the title screen music?

0x00fecb is the songid of the title screen (in hex) just use xvi32 (or equivalent editor) to change it.

How do I set invincibility? I need to set it up for a 419910 hack.

invincibility appears to be [49e6c8]

00419951      MOV BYTE PTR DS:[49E6C8],80

also in case you didn't see my previous post

Yeah it appears to be the level down effect.

 

How do you start a boss battle scriptwise? I apologize for being such a noob right now.
