But you didn't understand enough of what you were doing to know that you need to define variables before you use them.

Do I call the variable HealthPoint?
I've abandoned the HealthPoint thing for now.

local something = API.load "HealthPoint"

HealthPoint.setNPCHealth(npcID, Health)

something.setNPCHealth(npcID, Health)

I would recommend using rng.lua for sure. Also, do you mean after the player eats npc-263? That's the ?-mushroom. If so, you would start by loading rng.lua. Next, start with the onNPCKill() event and inside test to see if npc-263 has been killed. Then, if npc-263 was killed use the parameter player.reservePowerup and make that equal a random number (using rng)

This code works, but it's the shortest longest code in the world Can I somehow make it shorter?

Mario_and_Luigi_55 wrote: Yes. You can call it whatever you want for example:

Code: Select all

local something = API.load "HealthPoint"

But then you don't use

Code: Select all

HealthPoint.setNPCHealth(npcID, Health)

, but

Code: Select all

something.setNPCHealth(npcID, Health)

Health = 0

function Health.setNPCHealth(54, 5)

I've done what you've done and this is my new code:

Code: Select all

Health = 0
local Health = API.load "HealthPoint"

function Health.setNPCHealth(54, 5)
end

And the error I'm now getting says: <name> or '...' expected near '54'

From 54 I mean NPC 54 if that helps.

also this didn't work

What is the [code] bbcode,? Also you didn't tell me how I'm supposed to actually use hastebin.

It's not that hard. You just press paste. Then you press save. Then you copy the url and paste it here

I want to try to put a pointer to an NPC in 0x140, because otherwise an NPC i'm using in a simulated warp-type generator assumes its generator is to its right and immediately thinks it's "finished" if it's moving left.

If you just want to store references attached to the NPC, the best way is to wrap it with pnpc and using the PNPC.data table that is attached to all pnpc objects.

I'm not really sure what you're asking for here. All the memory locations in the NPC struct have specific types and uses, you can't just change it by trying to store an NPC object there, which won't work anyway. The closest you can get is storing the index into the NPC array, which is what SMBX usually does when it needs to keep track on an NPC.

Why are you setting your variable to 0 and then to the API you want? There's no reason to set it to 0 first.
