The code didn't crash when I added the other end but it's not making the blocks slippery. ???

Then use function onTick(). That should work

function onTick() also doesn't work.

Did you put next end?

[Hani]

Did you put next end?

Code: Select all

function onTick() 
end


for k,v in pairs(Block.get()) do 
   v.slippery = true
end

I think so..

I think so..

That way you qre ending function right after start.

Code: Select all

 function onTick()

for k,v in pairs(Block.get(id of block,-1)) do 
   v.slippery = true
end
end

Thank you! I finally know a little bit more of lunalua coding now.

Okay, so I've used the raocoin2 lua, and when I copypaste the code from the wiki, which is this:

Code: Select all

raocoin = loadSharedAPI("raocoin2");
rc = raocoin.registerCurrency(274, true, 472, 66);
coins = raocoin.registerMemCurrency(0x00B2C5A8,FIELD_WORD,true,false,0,0,"coins.png");

Then I load a level,and I get this error:

Code: Select all

lunaworld.lua:2: attempt to index global 'raocoin' (a nil value)

I swear this error is really annoying. Is it because you're not supposed to put it in a lunaworld file or something?

[Emral]

Looks like you don't have the api. You can download it from http://wohlsoft.ru/pgewiki/Raocoin2.lua and put it into your LuaScriptsLib folder.

How do I make Link-6 the only character with his own health bar for a whole episode?

[PixelPest]

How do I make Link-6 the only character with his own health bar for a whole episode?

Put this in your lunaworld.lua:

Code: Select all

if player.character == 5 then
    --health bar script
end

    --health bar script
end 

I thought you need to set the player to player 6. If the player gets hurt, it will go to player 2 or 1. Check if that is occurring, the set it to 6. That way, it will keep track, but if the health bar reaches 0, you need to use tbe "kill" command. It is later, so I can not think straight, bjt that should be the jeist of it.

Sorry, didn't read the whole question. You just have to do this then:

Code: Select all

if Player.character == 5 and Player.powerup == 6 then
    --health bar script
end 

That should work. Btw MECHDRAGON777 you can't just set "player" to something, that's not how that works at all for what you're trying to do

[Hoeloe]

That should work.

No it won't. You've used "Player" when it should be "player". There is a big difference between the two.

[PixelPest]

That should work.

No it won't. You've used "Player" when it should be "player". There is a big difference between the two.

Right. Sorry. So Mudkip, do:

Code: Select all

if player.character == 5 and player.powerup == 6 then
    --health bar script
end

Right. Sorry. So RoundPiplup, do:

Code: Select all

if player.character == 5 and player.powerup == 6 then
    --health bar script
end 

Mudkip is the one asking though... I never wrote the code for him to use because I can not reference the wiki while on a phone. I also do not have the entire wiki printed out yet as of today... I was just trying to help a little bit.

[Mudkip]

I copypaste'd the code you wrote but I still play as Link normally. Don't I need to activate the code first or something?

[Emral]

Right. Sorry. So Mudkip, do:

Code: Select all

if player.character == 5 and player.powerup == 6 then
    --health bar script
end 

What no
How is
how is what you're doing even remotely helpful.
He's asking how he should tackle a healthbar script and how to force the character to state 6 at all times.

While I won't write the code for you (mudkip), because it's important that you work this out for yourself, I'm gonna (unlike other people *nudge*) provide some sources and tips on what to do and how to tackle this.

-Setting the player to link and initially setting him to state 6 is no issue. Use function onStart() and player.powerup, as well as player.character, which you can find here:
http://wohlsoft.ru/pgewiki/Player_%28class%29
You might want to build in a check though for the latter.

-Setting the player powerup to 6 might be a bit tricky. If the player powerup was 1 before, link will start clipping through the ground. There are a few workarounds, but the safest is probably breifly setting the powerup state to 2 before setting it to 6.

-To impliment your own health bar you want to create a variable in the data class:
http://wohlsoft.ru/pgewiki/Data_%28class%29
The data class is a class which you can use to save variables between levels. Pyro made a tutorial on it, too: https://www.youtube.com/watch?v=dnTH_cBYZhs
By using it you can make a variable which will store the player's current HP. Once it reaches 0 you kill the player (once).

-The normal way how smbx handles health might sound to be obsolete, however you can still use it to detect changes to the player's hp.
http://wohlsoft.ru/pgewiki/SMBX_Player_Offsets
Offset 0x16 stores the number of hearts. Ideally you want this to be 2 at all times, breifly falling back to 1 when hit and going to 3 when getting a powerup for a frame or two. During that time you catch the difference and adjust your data class variable (and the player powerup if needed).

For a first-hand look on a health bar script like this, take a look at hudOfTime.lua. It does what I described here. Make sure to not copy the code though without having understood what it does, since else you might end up puzzled in a few weeks when something breaks somehow.
