Need help with lua? - LunaLua General Help

Just use Graphics.drawImageWP with the priority of the HUD - you can look up how to use it and what that priority is on the wiki.

OK so i played some levels with custom HUD and this happens (I had this problem since i updated my Lunalua from 0.7.2.2 into 0.7.3) also this problem happens with Hudoftime and SMB3 Overhaul

Looks like those levels used LunaDLL for the HUD. If you wanna replace the default HUD graphics, you can edit the hardcoded graphics using LunaLua, like h2643 did in his SMB2 HUD.

Invisible HUD icons happen to me too in level timer api. I have Lua 0.7.3.

I'm trying to give my enemies more health with the HealthPoint lua.
I've copied the HealthPoint.lua file into my level folder.
I'm experimenting using a Fighterfly and I'm giving him 2 more health points.
This is the code I'm using (excluding the spaces).

Spoiler: show

function onStart()
HealthPoint.setNPCHealth(54, 2)
end

When I test it, it gives me this error saying 'attempt to index global 'HealthPoint' (a nil value).'

My LunaLua isn't bugged (I think). I've tried the Red Birdo AI and it worked fine.
What am I missing here?

That's not how APIs work.
You don't need to copy anything. You just need to load the API in your Lua file using API.load, like this:

Code: Select all

local myAPI = API.load("myAPI");

It is possible, a way to increment like a combustible a timer like +1 sec. each time I get a coins
and when the 1 sec is over the coin stocked disappear ?

Thanks

I changed my code to this:

Spoiler: show

local myAPI = API.load("HealthPoint");

function onStart()
HealthPoint.setNPCHealth(54, 2)
end

And it still says the HealthPoint is a nil value error.

Has anyone else noticed that variables defined through pnpc's data property seem to have issues with generators & NPCs spawned from generators? Perhaps I'm using an outdated version?

nono, "myAPI" has to be "healthpoint".

"HealthPoint"*

[underFlo]

whoops, you're right. Didn't see that he capitalised it like that.

[Hoeloe]

I strongly suggest you read some Lua tutorials if you can't work out why this is happening. You're never going to be able to do anything if you have to resort to asking the forums for every small thing.

I'm copying from what it says in the HealthPoint lua.
I tired Misc.npctocoins and that's a nil value as well.

Next I tried putting local next to both Misc.npctocoins and HealthPoint.setNPCHealth and it says 'unexpected symbol near '.''
The Fighterfly still dies in 1 hit and doesn't turn into coins.

I suggest you listen to Hoeloe. For the record, Lua is case-sensitive.

That's not a Lua tutorial. You should learn the basics of how Lua works as a programming language if you need to do more than just copy and paste.

I was copying the functions in the lua file near the beginning.

I was copying the functions in the lua file near the beginning.

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

[Quantumenace]

Has anyone else noticed that variables defined through pnpc's data property seem to have issues with generators & NPCs spawned from generators? Perhaps I'm using an outdated version?

Could you be more specific? Are the entries getting shuffled to the wrong NPC or something?

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