But... you can kill her.

The npc wont' run the script, because they never actually "die", rather they become a different npc/ state after they get to a certain health amount. For Sue, I believe it's 500.

 

How do you lower the damage done by spike tiles?

What <SOU commands trigger the sounds for the big explosions that room bosses make and the sounds for Misery's lightning? Can you even makes those sounds with the <SOU command?

Alright, I need to make this thing change it's velocity quicker, so how would I do that?

Edit: This is the Homing Flame npc btw.

 

find
add [e_x+10] ___ (horizontal)
add [e_x+14] ___ (vertical)

and increase it

 

How do you get the debug save thing to work that you can see in Resource Hacker?

 

Oh, I found an easier way to do it, make one resource before the debug mode have the same value, 40005, and it should delete that one.

 

What's the highest possible HP that any entity can have?
Or is there a different way to make an entity immortal while it can still take damage and such?
(I had in mind something like practice dummies, to test out which weapons are useful at specific levels.)

 

Pretty sure this has been asked before, but can I prevent a weapon from reaching level 3?(Other than not including experience in stages or requiring 9999 experience)

you can always make an npc with like ~1000 health and set it to 1000 every frame
unless one of your weapons deals 1000 health in one blow you can never destroy it

 

Alright, how would I make the exp capsule change from spawning the amount of exp from the flag number to just adding the flag number to the exp of the current weapon.

Edit: Never mind I did it myself. It was quite easy, actually.

Mind telling us how then, I'm curious and may want to use such a feature in my mods

 

Alright I have it! The exp capsule now gives the exp directly to the weapon, instead of spawning it. The flag id determines the amount of exp, like before.
Code:

Spoiler

00457A4B nop
00457A4E nop
00457A51 nop
00457A52 nop
00457A55 nop
00457A58 nop
00457A59 CALL 004196F0
00457A5E ADD ESP,4

Have fun!

You don't need ADD ESP, 4. POP EAX will do just fine, plus it uses less space. It does run very slightly slower though, but that's not going to affect anything, since the game processes millions of lines of code every second anyway. You can also condense the NOPs into FNOPs since they do nothing anyway.

I believe you can only give NPCs 10 digits of health. I've made an NPC with 1000000000 health before, --unless your weapons are doing fuck-tons of damage--nobody will ever kill an NPC with that much health.
Also if you make an NPC run an event on death, and that event is, say 0, it will just end the event and the NPC will never die. Although this may let people skip H/V Triggers if they have the Spur and they can get the game to constantly run an event other than the H/V Trigger's event whilst they walk trough it.
If you want the illusion that the player is making no headway turn off the "Show Damage #" flag. In BL it's actually the second "Interactable" flag.

you can always make an npc with like ~1000 health and set it to 1000 every frame
unless one of your weapons deals 1000 health in one blow you can never destroy it

Max HP = 2,147,483,647 (dec)
7FFFFFFF (hex)
More than that and it will go into the negative (since the values are signed)
So it's larger than 1,000,000,000
But even if you've filled all weapon slots with bullets dealing the max of 127 damage/frame, you'd still only reach about 406,400 dps. That would take half an hour to kill an enemy with 1,000,000,000 HP, and over an hour to kill one with 2,147,483,647

Pretty sure this has been asked before, but can I prevent a weapon from reaching level 3?(Other than not including experience in stages or requiring 9999 experience)

Find some empty space or optimise the weapon slightly, then add in a CALL 0419890

Spoiler: Easiest way

Easiest way to do it is to replace the
MOV ESP,EBP
POP EBP
RETN
with
CALL 419890
LEAVE
RETN
You'll have to use some of the INT3s after the command, don't use this method if there's no space.

This will prevent it levelling up at all. If you somehow level it up in 1 frame it levels down instantly the next frame

I got to 110. But I think I know why it broke the game. Cave Story is just very tricky.

from what I remember, you could have something like over 180 maps with cave editor and like thousands with boosters lab (I remember noxid saying this somewhere, but I can't remember where).

It appears that more than 0x80 maps will write into the player's flags! Probably not the best idea.
I've created a working (hopefully) hack that allows you to have up to 256 maps in total:

Okay guys, now for my question.
Why can you only give NPCs a direction of up to 4 using <CNP? It's a DWORD value!
