Yes, it still hides the HUD and I can get the PrintText function to work. But the image codes don't work.

Mhh.... could you send me your level with the code and images or at least the code and images?

Anyway:


LunaLua is now v0.5 BETA. We can now run code in the overworld YAY!
To run your code for the overworld make a file called "lunaoverworld.lua" in your episode dir.

Following events can be used for the world:

Spoiler

* onLoad
* onLoop

Following functions can be used for the world:

Spoiler

* windowDebug
* printText
* loadImage
* placeSprite
* mem

Classes are not supported yet!

A small Q&A to that:

Spoiler

Q: Can we run Autocode (lunadll.txt).
A: No you can only run lua code.

Q: Could you implement Autocode for overworld?
A: I could, but it would take way too long time. If kil does it then I am fine.

Q: Can we deactivate the world HUD?
A: No (maybe later), but the render code is the last painting code which is called. So you can overdraw everything if you want to.

Q: Why BETA?
A: There might be some bugs floating. If you have any issues please report them to me!

Okay, I just noticed that you are missing a HUD folder!

This code should work:

Code: Select all

function onLoad()
  loadImage ("HUD/hud.bmp", 1, 0xdc00ff);
  placeSprite (1, 1, 174, 8)
  hud(false)
end


[Sambo]

I just tried that, and it still won't load the images. I'll try downloading v 0.5 and see if it works.
Also, the HUD code only works if it's placed under the onLoop function.

EDIT:Just downloaded v 0.5, and it finally works now. How do you type in the filename to go BACK a directory? I have the codes in the lunaworld file, but it still starts from the level's CGFX folder. I would like to go back a directory so I don't have to create a copy of my HUD image for each level.

[Kevsoft]

simple do "../HUD/yourImg.bmp"

Added after 6 hours 45 minutes:
And here is the first LunaLua update for the overworld adding now the world class!
Example Code:

Spoiler

Code: Select all

function onLoop()
   local output = ""
   if world.playerIsCurrentWalking then
      output = output .. "Running "
   else
      output = output .. "Looking "
   end
   
   if world.playerCurrentDirection == ODIR_UP then
      output = output .. "Up"
   elseif world.playerCurrentDirection == ODIR_LEFT then
      output = output .. "Left"
   elseif world.playerCurrentDirection == ODIR_DOWN then
      output = output .. "Down"
   elseif world.playerCurrentDirection == ODIR_RIGHT then
      output = output .. "Right"
   end
   
   printText(output, 10, 10)
   if world.levelTitle then
      printText("Current Level: "..world.levelTitle.str, 10, 30)
   end
end


Changes for LunaLua 0.5.2:

Spoiler

* Added world class with following functions and properties:
** field double world.playerX
** field double world.playerY
** field int world.playerWalkingDirection
** field int world.playerWalkingTimer
** field int world.playerWalkingFrame
** field int world.playerWalkingFrameTimer
** field boolean world.playerIsCurrentlyWalking
** field nil or VBStr world.levelTitle
** function mem

Documentation will be updated soon!

Thank you for all the help.

EDIT: Is there a way to count number of NPCs with a certain ID, like, for example, if I wanted to return the number of Dragon Coins in a level?
Also, how do I make a counter that goes up every time a certain NPC is destroyed?(with more than one of that NPC in the level)

[Kevsoft]

if I wanted to return the number of Dragon Coins in a level?

Code: Select all


function countNPCID(id)
  local npcs = findnpcs(id, -1)
  local count = 0
  for k,v in pairs(npcs) do
    count = count + 1
  end
end

function onLoop()
  local goombaNPCCount = countNPCID(1)
  if goombaNPCCount == 5 then
    --do stuff
  end
end



Also, how do I make a counter that goes up every time a certain NPC is destroyed?(with more than one of that NPC in the level)

I could do it but with the restriction, that the type of that NPC has no spawner, or in other words: The value should not increase.

[Sambo]

Is there a way to make it so an onLoopSection# function can have multiple section numbers? I don't want it to be for the whole level, just all the sections except for 1 or 2 of them. I would just do:

Code: Select all

function onLoopA()
  ...(stuff I want it to do goes HERE)...
end
function onLoopSection1()
  onLoopA()
end
function onLoopSection2()
  onLoopA()
end

...

end

But since the codes are run from lunaworld and this would only be for 1 level (lunadll), That wouldn't work in a way that wasn't a total pain to deal with, because I'd have to add all those codes to every level.

[Kevsoft]

You can use player.section in onLoop:

Code: Select all

function onLoop()
  if(player.section == 0 and player.section == 1)then --section in lua are 0-20!
    --dostuff
  end
end



Please note that this only works for 1-player mode. If you want to use it for 2-player mode you have to also check player2.section!

[Sambo]

What I'm trying to do is make it so my custom HUD is hidden while in sections 4 and 5, on just one level in the episode, while the HUD functions are run from lunaworld.lua.

[Kevsoft]

You should be able to access variables from lunadll.lua in lunaworld.lua and the other way round.

This is a code that's supposed to save the user data when the checkpoint is reached, but it will not work. I get the checkpoint and die, and then test the level again and the values are the same as they were before. This is really odd because it was working earlier and I didn't change it. I didn't update LunaLua or anything. It just stopped working.

Code: Select all

function countNPCID(id)
   local npcs = findnpcs(id, -1)
   local count = 0
   for k,v in pairs(npcs) do
      count = count + 1
   end
end
function onLoop()
   local checkpoint_count = countNPCID(192)
   if checkpoint_count == 0 and checkpoint == 0 then
      UserData.save()
      checkpoint = 1
   end

[Kevsoft]

Code: Select all

function countNPCID(id)
   local npcs = findnpcs(id, -1)
   local count = 0
   for k,v in pairs(npcs) do
      count = count + 1
   end
   return count
end


I probably forgot to tell you that you have to return the count value!

With return you can set the value you get from a function.

[Sambo]

Oh, that was an obvious mistake.
I know how the return command works and I still didn't think to add it in.

You should be able to access variables from lunadll.lua in lunaworld.lua and the other way round.

I tried to access functions from lunaworld.lua in lunadll.lua and got "attempt to call a nil value." Functions are a type of variable, right?
