Need help with lua? - LunaLua General Help

[underFlo]

Can I somehow change npc health? For example if I want goomba to die on 3 hits instead of one.

I found a api on the PGEwiki that does this.

then...why are you not telling him what the API is called?

here's the link for that btw

Well perhaps you should look at the error message? It clearly says the get() function doesn't have a matching overload. AKA, one of the get() functions ur calling has incorrect parameters.

But then how would you double check which one is wrong? A good look at the docs would help you very much.

You have an error with an lunadll.lua on line 12 in conflict with an callEvent located in the SMW Borderlands folder.
I dont think it's with "iwoyozegal.lua" file.

and why are you using colliders ? you can do it with

Block:collidesWith(Player player)

Returns a number with the side of the collision.
0 = no collision,
1 = Player on top of block,
2 = Player touching right side,
3 = Player touching bottom,
4 = Player touching left side.

This is wrong. The error is in that file. That file is a lunadll.lua file, hastebin just gave it a unique ID for hosting.

The problem is that Block.get doesn't work like that. You can't specify a section number for Block.get, so the "-1" there is invalid.

That aside, if you're using colliders you shouldn't be doing it that way. There is a function called "collideBlock" which will be a lot faster and neater. Instead of using a for loop and looping over all the blocks you might want to test against, you can just do:

Code: Select all

if(colliders.collideBlock(colliders.BLOCK_HURT, player)) then

Which will account for every "hurt" block. If you want lava as well you can do this:

Code: Select all

if(colliders.collideBlock(colliders.BLOCK_HURT..colliders.BLOCK_LAVA, player)) then

You can take a look at the stacktrace which will trace the origin of the error. In this case:
mainV2.lua line 301 called in..
lunadll.lua line 12 in function..
lunadll.lua line 11.

You want to look at the first reference of the file you are currently modifying, which in this case will let you know that the error is a wrong overload in Block.get() in line 12. A quick look at the wiki reveals that Block.get doesn't have a section parameter, like hoeloe said.

Okay. Thanks Hoeloe and Enjl. So if I can't specify the parameters of Block.get(), should I just implement w.id or is there a better way I should do it?

You misunderstand. Take a look:
http://wohlsoft.ru/pgewiki/LunaLua_glob ... _functions

You can grab by ID, but there's no section parameter.

Okay. That makes sense. Only saw the first one. Thanks again

[PixelPest]

Okay. I'm stumped again. I have a stable code, but it doesn't do what I want it to: http://hastebin.com/dacahiyute.lua

My intention is for the player to be killed any time they touch one of the listed blocks, however they're not. It does work though if they are riding the airship piece. Any ideas?

Fixed! Don't use colliders, just use the native Block:collidesWith(player)
Fixed version: http://hastebin.com/wohayehofi.lua

By the way, you don't need to use semicolons in Lua

[underFlo]

There's no problem with using them though.

[PixelPest]

Thanks for the help but I already got it fixed up and should have taken it down. The issue was with the hitboxes anyway. I'm going to keep using colliders.lua and my semicolons

Nice some one finally listen me thanks Nerx !, I knew it, it will work
Earlier quote from me :

Block:collidesWith(Player player)

Returns a number with the side of the collision.
0 = no collision,
1 = Player on top of block,
2 = Player touching right side,
3 = Player touching bottom,
4 = Player touching left side.

I have a question about boundaries, is there a way to add a square and create it from a Rectd class and adding more boundaries than 1 at at time ?
thanks, I hope yes because I have few many ideas with this

collidesWith and colliders are two different things. I'm using colliders.lua, the API, and colliders.collide(obj1, obj2)

Why use a library when there are built in functions to help you?
Glad to see you fixed your problem though.

It's simpler and I'm already using colliders to make custom hitboxes anyway

[pal4]

local hasGenerated = false;
local ran;

function onLoop()
tableOfBirdo = NPC.get(39, -1);
tableOfBirdoEggs = NPC.get(40, -1);
Text.print(tostring(ran),0,0)

if(tableOfBirdo[1] ~= nil) then
if(tonumber(tableOfBirdo[1]:mem(0xF0, FIELD_DFLOAT)) = 1) then
if(hasGenerated ~= true) then
ran = math.random(0, 2);
hasGenerated = true;
end
if(ran == 2) then
if(table.getn(tableOfBirdoEggs) > 0) then
tableOfBirdoEggs[table.getn(tableOfBirdoEggs)].id = 282;
playSFX(42);
end
end
end
if(tonumber(tableOfBirdo[1]:mem(0xF8, FIELD_DFLOAT)) == 280) then
hasGenerated = false;
end
end
end

How do I use it, and how is it supposed to help?

[Emral]

It's so your code is actually formatted well. You can also use the

Code: Select all

 bbcode but that's limited to like 6 lines at a time. Just pasting it to the page makes it unreadable.

Is that possible if i add an image into the default HUD with Lunalua?
if yes tell me how to do it pls.....
