Just replace a goomba or something. The hiding part of boos is unchangable to my knowledge.

Can't you set it to always be in one AI phase?

Not with boos. I tried.

I believe you, but maybe you could use another boo? I know the brown donut block can't move in the same ways with Attach to Layer as a red one.

I tried changing the speed of boos with npc codes, but it doesn't work. Is it possible to increase the speed of boos using lunalua?

What NPC code did you use? It should be possible with them.

He probably means up and down speed which is not possible with npc codes.

Okay. I thought he was referring to just the speed in general.

Is it possible to make a fireball shooted from a Fire Piranha melt the ice blocks like the player can with a fire flower?

I'm working on a post-game feature of my episode titled "Life Factory" where the player can trade 99 lives for one of the special power-ups. How can I modify the player's life count without killing and respawning the player over and over? Also, the 99 lives trade-off gives you a modified fire flower power-up, a tanooki suit (not found anywhere else in the game), or a special hammer suit (hammer suits aren't found anywhere else in the game either). So, how do I load alternate graphics and text files for the fire flower power-up onEvent, that will automatically replace all fire flower related graphics and add the text file for the fireballs that currently are in the main episode folder?

http://engine.wohlnet.ru/pgewiki/SMBX_Global_Memory for the life counter.

http://engine.wohlnet.ru/pgewiki/PlayerGfx.lua for a new fire flower spritesheet.

http://engine.wohlnet.ru/pgewiki/Npcconfig.lua for changing npc codes at runtime.

Thanks. Those are extremely helpful.
But how do I use HUD Lives Count? I want to check to see if the value of HUD Lives Count is equal to another value (99) and if true subtract a value of 99 from HUD Lives Count?

[underFlo]

mem(0x00B2C5AC,FIELD_FLOAT) returns the life number
mem(0x00B2C5AC,FIELD_FLOAT,lifecount) lets you set the amount of lives to "lifecount"

[Emral]

Yeah you can get and set mem(0x00B2C5AC, FIELD_FLOAT) and do exactly what you just described.

wow nice ninja geez

Transferring some of my layer movements to Lua, I ran into a problem Hoeloe also pointed out: http://talkhaus.raocow.com/viewtopic.ph ... &start=250

When the player gets a powerup or gets hit, all layer movements and basic event timers are paused briefly, but Lua is not. (generators, NPCs, and attached layers aren't either.) That can throw off the layer positions because the script assumes they have been moving. Defines.levelFreeze accounts for stopwatches but not this.

I did find a workaround that uses a test block on an oscillating test layer. If the layer movement is "paused", including from stopwatches, the block's speed will register as 0 instead of the layer speed. If that's the case you can tell your script not to update its layer script for that loop.

Is there a simpler way to check this? If not I'll post the code. It's still far from ideal because you have to manually place the block and type in its coordinates to find it. As far as I know you can't use script to place a block on a non-default layer. Blue P-switches also make it lose track of the block and freak out.

[Emral]

Normally SMBX discontinues layer movement while the player is in a forced animation state. There's a player mem offset for that state (0x122 I believe). Just check if that's 0 and only run your code inside if it is.

Also, you can do block = Block.spawn and then block.layerName = "string"

[Quantumenace]

It looks like 1, 2, 4 and 7 are animation values associated with frozen layers, the others don't pause them. Is there a global memory offset that stores whether the layers are paused?

As for the block, layerName is read-only

[Emral]

oh really? I remember 500 pausing stuff like NPC platforms at least. You can still single out the forced frames by adding conditions to the if clause. If, for example, 1, 2, 4 and 7 are frames which bother you and shouldn't run the code, you type:

if (player:mem(0x122, FIELD_WORD) ~= (1 or 2 or 4 or 7)) then
your code
end

(I think this should work. I'm not too familiar with fancy stuff you can do in if clauses.)

[Quantumenace]

Oh, 500 does pause it, it's just so short it's hard to tell by just watching the layer. Same with 8. I know that 3 (pipe) does not, however.

There appear to be other values, like 11 for getting the Tanooki powerup, 41 for ice flower, 12 for hammer. It may work to just check whether it is 0 or 3.

I may just go with the block as an indicator, I don't intend to use P-switches anyway.
