JSL $01A7DC only seems to make him jurt you if he hasn't been hit yet. If he has, then he starts going through you again.
the table used by the sprite to store HP must be used for another prupose in that routine
In that case, then, what should I do differently so that he hurts you on contact all the time?
you fix the previous stuff by locating the table that store the HP to store it to another table(look at the RAM map to find some mostly unused one), I belive the table is $c2 but I'm not too sure.

Also, your post make it sound like you want us to do it for you>_<
Huh? I was only asking what it was I needed to do next. I was never trying to get people to do stuff for me.

Anyway, thanks. I'll try that in the morning. It's about 12:30 AM in my timezone, so I'll be hitting the hay soon.
well, the code it's supposed to amke mario "cape swing damage" if he touches an enemy at max speed, but It doesn't works.
There isn't another way to make what I'm trying?
thanks for your help, anyways

It is my turn to ask a question now!


I have a DMA code (Channel 1) that uploads Layer 3 tiles to the screen, shows them up and stuff (NOT a code to upload custom layer 3 tiles to the tilemap.) I have a problem with it though:

When I use it in a normal level, it works correctly

When I use it in the title screen, it won't work at all.

someone can help me Can someone help me making it show up? I'll post the code here if needed.

--------------------
My blog. I could post stuff now and then
Okay, can someone else help me out with a sprite?


Code
	PHX
	LDA #EVENT_TO_CHECK
	PHA
	AND #$07
	TAX
	PLA
	LSR A
	LSR A
	LSR A
	TAY
	STZ $00		;generate mask, due to lack of absolute addressing for blocks
	SEC
LOOP
	ROR $00
	DEX
	BPL LOOP	;X = shift count	
	LDA $1F02,y
	AND $00		;mask
	BNE EVENTSET
	PLX
	JSR DOWN_GEN
	RTL

EVENTSET
	PLX
	JSR UP_GEN
	RTL


SNN got me that code for making the Door Generator sprite generate a block depending on the status of an event. I've been trying to modify it to react to a certain RAM address instead, but when I get back to the level after said address is set to the right value... The screen goes black. The game crashes, essentially. D:

Code
	STZ $00		;generate mask, due to lack of absolute addressing for blocks
	LDA $0662
	CMP #$00
	BNE EVENTSET
	JSR DOWN_GEN
	RTL

EVENTSET
	PLX
	JSR UP_GEN
	RTL

RETURN              RTS                     ; return


Then there's the smoke-generating routine...I doubt the problem is THERE...


<Adam> I feel like smwc is a prostitute now, because we put up a porn ad for money

Remember, people! Telepathy is a wooonderful magic!
I'd answer Lucario's question, but we already talked and stuff in IRC and I was kind of having the same problem, so yeah.

Anyway, quick question of my own. Know how you can use the "Midway Point Passed" checkbox on levels on the overworld so that, after the level is beaten, the midway point was set permanently? Is it possible at all to do this within a level, or is there some specific table where these midway things are stored? I have no idea about it, to be honest.

Thanks.

I can probably use it, Because I need to make the status bar in Layer 2. (Or use both Layers 3 and 4.)
I seem ti have an ASM problem of my own.
I tried to make the mouser sprite work with the level ender sprite but but the level ender sprite actives before the boss fight can even start.
how do I fix it?

Do you ask for my code or something? >_>

Also, if you use Layer 4, you need to use Mode 0, which forces all Graphics to go 2bpp format or something. Unless you use IRQ or HDMA...

Anyways, here is the code:

		LDY #$01 	 ;2 regs write once alternate 
		STY $4310	 ; meaning this will write to $2118 and then $2119 back and forth

My blog. I could post stuff now and then
What do I have to write (ASM) to make a block turn into the next tile in the Map16 (Or, if that's easier, into tile 25)?
It should execute some code and after that, it should be invisible and not do anything.

Be patient next time ~ Ersan
Wow... you've been waiting a whole 16 hours!!!!!!!!!!!!!!!!





Please get a clue and realize that no one is obligated to help you. The notion that people have been making you wait to make you upset is absurd as well.

Basically, you should go up if you press Up and down if you press Down (along with some additional stuff, determine your position and those of blocks). The block is not entirely complete with every feature, but even THIS fails to work. Someone help me out? I'm branching in a wrong way, so how do I do it?

This code SHOULD make the player invincible while they are ducking. However, it just crahsed the game. What needs fixing? (I'm assuming it's the org part, but I don't know.)

Hmm... I'm not an expert in this but did you traced it through the debugger? There's some code missing, I just don't exactly know what. XD | The org part tells where you want the code to be inserted. Search an empty string in your rom with a hex editor, then convert the starting adress in Lunar Adress and the result is the number you add after "org".

Also, don't forget, if the code goes over 5 bytes, you have to add a NOP or more depending on how much bytes it is.

I hope you had a backup. You corrupted some routine.

Put "ORG $1FB000" before "Duck:" (the label)

You can change $1FB000 to an SNES PC address which has free space.

Now patch it to the ROM.

Okay, so this is what it looks like now. I added the org $1FB000 right before the duck label, like you said. When I patch this to a clean, unmodified ROM, it doesn't even make it to the "Nintedno Presents" logo. If I patch it to any modified ROM, it will make it all the way to the intro screen, but crashed right before displaying the welcome message.
