Darn. That makes sense. Well, thanks.

EDIT: Unless...!
I remember seeing a separate npc that's a defeated Gaudi! Maybe I could just put the run script on death flag on that!

I'm not sure.

I'm using Cave Editor... Do the flag checkboxes in the npc editor correspond to the ones in the map editor? 'Cause some of them have different names. Is there a run script on death button in that menu?

I'm quite all right with having every gaudi death run the script.

 

What Serkol said.
Gaudis, butts, and other enemies have extremely large health values and magically transform into other npcs once their health drops below a certain threshold.
That's why changing their health with npc.tbl doesn't do anything, and also why runondeath won't work.

 

Edited my post. Anyone know if that might work?

 

Welllllllll when npcs are created ingame they get a script number of 0000 automatically.
Even if you make those npcs always run an event on death, that event number will be #0000 (unless you hax), so you'd have to restructure the way your script works if you wanted that to wok.

 

Ohh, I see the issue there.
Wait, restructure the way the script works? How? Why? You mean like with ASM?

Couldn't I just make the script that I want to run at 0000? or does the game not allow a script number 0000...?

 

What I meant by the restructuring is that you'd have to change every YNJ and anything that goes to event 0000.
Which is quite a few things

 

Oh, that's not so bad. Besides, I'd only have to do it in the levels that have gaudis! Thanks!


EDIT: Hmm, the Defeated Gaudi entity does not seem to be the same as the defeated gaudi. Changing flags on it in the npc list doesn't seem to do anything. Can you point me in the right direction?

 

can anyone please explain the "run script on death" flag to me? I've flagged a gaudi with it, and put its event number in the script. For some reason when the gaudi gets killed, though, it doesn't run the event. And it still drops shinies when it dies, which I remember shouldn't be happening if it's got that flag on. Anybody know the problem?

Gaudi have very very high health values, and their AI (that is, ASM stuff) watches that health value. When it drops a certain amount, the AI changes the npcID to that of the defeated gaudi, which then kills itself and spawns loot. The reason run script on death will not work on gaudi is because that event is handled inside the bullet x npc collision function (00471D50), and it relies on the npc's health being below 1. In other words, what you want to do is not going to work unless you tweak the gaudi directly (that is, ASM.)

However, what you want could work if you added a clause in (00471B80) [enemy dies] to handle checking flag 200 and an eventnum. However, doing just that would end up having any npc with flag 200 running their script twice, since the latter would also get run from (00471D50). It's perfectly doable, sure. But it's not as simple as it looks.

Tiles 0x0-0x1F are behind the player
Tiles 0x20-0x3F are never drawn
Tiles 0x40-0xFF are in front of the player

I should point out that the game only knows how to handle tiles up to something like 0x70 or such. If you use higher values it starts to act weird. That is, if iirc. XD

 

Well I think values that are higher than the max expected (that is, the max pixel programmed for that collision group) get caught by the default value of the SWITCH statement he uses, and nothing happens (effectively same as tile type 0)
I can't remember any issues with the rendering engine that would arise from high values either.

 

Hmm... Is there any list of bullet offsets anywhere? There isn't one in your amazing assembly compendium, Nox. :/

 

I had one. I dunno whether it got lost with my hard drive.
One sec.

Awesome! Thanks, Lace!

 

No problemo

 

How to change sound that weapon makes when the bullet is shot?

 

...
Um... How to change weapon's sound when the bullet is shot?
In assembly or in hex, if it's necessary.

.__.

Look for calls of 0x420640.
PS: Use your resources before asking questions. I found that function in like thirty seconds here.

sorry

I forgot to look

How to change behavior of boss?
I only want to add some new projectiles to him.

 

Requires some vicious assembly. You'd have to locate and rewrite the boss script I think.

Where are the fireball's/snake's framerects located in the .exe? I've found the bullet.pbm framerects since they're in the bullet code, but I can't find the framerects for caret.pbm.

 

I'm assuming you mean the trail. I'd guess that it's probably an entity, which one I havent' a clue.

 

So I should look through the npc scripts to find the framerects? I don't really understand.

 

You should look through the NPC list to find the one that's the trail for the snake/fireball
Failing that, it isn't listed, so you should look through the code of the fireball/snake to find out which entity it spawns and then tell me so I can add it to the list.
