So can someone help me on how to actually do it?

Thomas Xin · Feb 8, 2016

Here's the code for damage:
PUSH [VALUE]
CALL 00419910
ADD ESP,4
So the damage code is in 419910.
Now let's check the data.

EDIT: Looks like it removes XP as well; I think that you'll have to decipher the random stuff above for the XP I'm too lazy
EDIT: Also I think that the format thing doesn't work in this forum. Ceebs fixing it

If you want to remove HP without XP, you could always set a LI+ 000/ to add negative 1 health
or LI+00/9 for -2, LI+00/8 for -3, LI+00/7 for -4 etc.

Or you could remember the true negative values but I'm too lazy to check that either.

Does adding more maps to the game through cave editor (the most recent version, 0.99d, I believe) mess with the .exe file at all? I've run into a problem where after adding a few extra maps, the scripts don't work right on the higher numbered ones.

do not add extra maps with cave editor

That is self-evident, I should think.
Is there any way I can add extra maps, or delete/replace the original ones en masse without having to go through the tedium of deleting/replacing the old ones individually?

Noxid · Feb 14, 2016

uhh.. with Booster's Lab?

GIRakaCHEEZER · Feb 14, 2016

I'd just recommend overwriting old maps as needed, since it's the least likely to mess up your executable.

To more directly answer your question, problems usually don't arise when you use Cave Editor's copy map feature and edit that copied map. If you use the "add map" feature, then this can make backgrounds have trouble displaying properly. Still, as GIR implied, it's really rare that you'll actually need to add a new map, so it's best to replace existing maps if you can. Also, I don't think Booster's Lab's add map feature is broken.

Q: Is there a way to skip the transition between screens?

You mean the fade out (<FAO) between rooms?
Well instead of:

Code:

<PRI<FAO0004<TRA0042:0094:0029:0080

Do:

Code:

<PRI<TRA0042:0094:0029:0080

And remove the fade in (<FAI) command from #0090, #0091, #0092, #0093 and #0094 if you really want to, but it won't change anything if you don't put a <FAO.

Thank you. I thought <FAI,<FAO meant "Fade In","Fade Out" for something else.
But, I can't find #0090.

Slither · Feb 15, 2016

Oh important! If you're not using <FAO you shouldn't use <FAI either because otherwise it will still try to fade in but look really weird.

Where is the health Misery has to reach before she starts spawning the double/quadruple black rings around herself stored in the executable?

Probably a check in her enemyAI, I'd read it through to see if you can find it there if I were you.

Help. This makes no sense.

misery is not a big boss, she's an NPC kind of boss

This is how much damage she can take before teleporting, edit the 50 (you can't exceed 7F so be careful here; unless you change the code a bit but I am too lazy to show you how atm)
e: okay, if you need this for some reason this should work for 80+

just fun stuff

As for the rings

these two ^ & v

cheers

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?

I really would recommend you just take the time to learn ASM yourself, since finding a good hacker who is willing to help others with their projects on the forums will probably be difficult.

What do you mean by that? Because as far as I know Spur pierces the enemies (or does it only do that on kill?), and I can't really find any other meaning to that at the moment.

Other than me.

I think zxin refers to the invincible entities like Monster X's wheels, horizontal presses and most of Ballos during the second and third phases.

Hina · Feb 16, 2016

zxin said:
Indeed I do.
I want it to be able to go trough (with or without damaging) entities and bosses.
This might involve completely cutting out whatever checks for the solid entities.

That sounds at least a bit complicated. Well, I'm not touching it, I guess.
BUT:
Technically, you could make Spur fire an NPC instead of the bullet (the leading one) and make it spawn the trail bullets, I think that's the easiest solution to your problem, because NPCs can pass through other NPCs no matter what.

I tried. I really did. But for the love of hacking (and google), I cannot figure out how to into OllyDbg. D:
Basically my problem is, I noticed that OllyDbg doesn't show the entire executable's ASM code at once. It arbitrarily starts at 0x77A90000, and I cannot figure out how to make it show everything or how to jump to the proper address. [The inconsistencies in the Assembly Compendium's hex addresses is quite a prick in my side, but I think I can manage.]

You mean this?

Might be a different version, but welp.
