Quick Modding/Hacking Answers Thread

@Fixer90 you only need post once and then edit your old post, double posting is frowned upon.

He didn't double post, he made two threads which both got merged into this one

This is why you shouldn't try to comment on other people's behaviour

 

Right. Since nobody is telling me the offsets for the boss HPs, I've figured it out for myself.
Monster X: 0x047E813______________________________MOV DWORD PTR DS:[ECX+40],2BC
Balfrog: 0x04793E4________________________________MOV DWORD PTR DS:[ECX+40],12C
Core: 0x04744CD__________________________________MOV DWORD PTR DS:[ECX+40],28A

Undead Core: 0x04754C0____________________________MOV DWORD PTR DS:[ECX+40],2BC
Heavy Press: 0x047C985_____________________________MOV DWORD PTR DS:[ECX+40],2BC

If you also need the HP offset for Omega, here you go.

@TLincoln:
Oh oops I forgot that sorry

EDIT: Looking at it again, it's the only boss health that doesn't use [ECX+40].
I wonder why.

Awesome, thanks. Still need help with the big bosses health, but this is a good start.
Also would someone be able to help me make the spur go trough solid entities?

Oh yes. I'm sorry to answer this so late, but I'm going to answer this now. I sorta forgot how to do this, since I did it a long time ago.
I think it was because for the Spur bullets, I set all the flags except 'Ignore Solid' and 'No destroy Solid'.
Either that, or just change the number of hits and damage to a ridiculously high value and it'll go through.

EDIT: Oops double post. Meh

From the wise words put in this post:

Omegas coding is so wierd

Really though, when I was making CSTSF Mod, I took a guess based on this thread. The offsets didn't really match up, but they were close, and it worked. And I guess I never bothered to mention it at the time.

 

Thank you both very much.
Now I can make Ballos truly impossible.

If you're just gonna give him a shit ton of health, then that doesn't really count.

 

How come when you give the blade ammo, an try to shoot(...?) It, the ammo doesn't deplete?

 

because it wasn't programmed to use ammo

 

because it wasn't programmed to use ammo

Ok then... I mean... every other weapon is apparently programmed to use ammo, except for the blade...?

So another question, is there like, an offset where I could change what type of bullet curly shoots when she's on your back?

 

@zxin:
If you're going to give the booster infinite fuel, just change the 32 in
4157A1: MOV DWORD PTR DS:[49E6E8],32 for Booster v2.0;
4157B7: MOV DWORD PTR DS:[49E6E8],32 for Booster v0.8.
Otherwise you could do the <IBF command:

; <IBF Infinite Booster Fuel
; 0002 = infinite fuel
; 0000 = not infinite fuel

^That's the <IBF command.

@Kenzo ITC:
Curly can only use 2 types of bullet: Polar Star and Machine Gun.
The most I know about Curly AI is that its offset is 0x044B210
EDIT: Oh I thought you meant Curly AI. Yes, you can change the bullets shot by Curly Carried.

 

So another question, is there like, an offset where I could change what type of bullet curly shoots when she's on your back?

You can, and it's hilarious when you do. I changed it once to fire fully charged spur shots and it was great.

I don't remember the offest off the top of my head, but check the AI function for the "curly on your back" entity (it'll be an entity in the top left corner of the hell maps where she appears).

 

I have a question. I was editing some asm stuff and looks like I messed with the wrong offsets, because now my mod crashes whenever I level up any weapon. The crash is an access violation at 0x0040C7A6. Could you guys maybe find the problem?

 

looks fine to me

 

the jet puffs are tied to the amt of fuel it has. So if you keep the fuel a constant #, it will either always or never puff.
The correct way to do it is to make the fuel reset when it hits zero but that's more work.
