how do i change the direction of an npc? for example, when i enter a room cthulhu is facing the left side. how do i change it so that he always faces the right side?

check the "spawns with alternate direction" flag

 

check the "spawns with alternate direction" flag

no wonder i couldnt find it. i was using cave editor instead of boosters lab. thanks!!

 

Hey, anybody have the offset for the sprite rect of the white pixel used for the map system? The modified zero I'm using doesn't have a pixel in it's normal position, so the map currently doesn't show where the player is.
Edit: Clownancy found it for me, it's in the four commands starting at 0x14646. To change them to be the pixel before the normal map pallette, change the 0 value to 0xEF, the 39 value to 0x18, the 1 value to 0xF0, and the 3A value to 0x19.

I think in Cave Editor it's option 2 but I'm not sure.

 

How exactly does Noxid's animated tiles hack work?

 

tile types are mirrored onto the unused half of the tile types mapping

if you give a tile a type on the right half, it'll function identically to the regular type but be animated. animations have a 3 frame loop and frames for animated tiles are taken from the two tiles directly underneath the animated one. you don't need to set the types of the animated tile's other frames but you can if you want to.

 

What's the event and sprite number for a health upgrade

 

What's the event and sprite number for a health upgrade

If you're talking about life capsules, then the "sprite number" for that entity is 32. The actual event number and flag ID is what ever you set it to, though. If you're talking about a health refill station, then the sprite number and default event number are both 17.

 

Thanks

 

alright so this is likely just a user error thing but,
I'm trying to use doukutsu assembler to apply a hack written in doukutsu assembler
more specifically, hina's no gravity fireball bullet found here
i've tried several of them in DA and every time get something along the lines of 'line number 10 line contents setnpinter unable to recognize this command
I figured I'd try to actually apply some previously made hacks using DA first before writing my own, but this is confusing me to no ends since what I know of DA and assembly it should be fine

 

"setnpinter"
vs
"setpointer"

 

the line contains setpointer
and it doesn't matter if it's exactly that either

EDIT: to clarify, i think it's trying to read the line as 'setnp'+'inter' instead of 'setpointer'

well are you missing the defines.txt that has all the custom commands in it because you need that too

 

that was my problem. I had the custom file just. Not in the folder. thanks a million

 

So, i was using the mimiga mask hack and when it gets above MIM0063, there's a black square around the character sprite. The problem is that i check the mychar file and there's nothing more than just 000000 black. Any clue as to why it happens?

 

Is there a way to make the curly a.i work in any map? Because it only works in the labyrinth, whenever I put the curly a.i in a different map she will just stand there MENACINGLY.

She needs to be ANP'd into action, should be like state 10 or 20, but you can check the first couple of events in the Labrynth map.

 

Does anyone know how to make a critter you can talk to that won't move?
Whenever I add the 2000 flag thing it still moves but it can't hurt me which is good, but I don't want it to constantly be moving around.
I did this before but I forget how??

 

you could either hack in a new/change an NPC with assembly, or just use the <ANP command on it I think, to set it to whatever makes it not move. I think.

 

Or you just put critter sprites on a npc that doesn't move.
