x is expected near y means that the code expected x where it found y. For example if you write:
if ... do

then it will tell you "then expected near do"

This doesn't make sense to me.

It means you've got a ) somewhere without a matching (.

Alright so I'm doing a thing and there's a thing I can't completely get to work.
First of all, here's the fabulous code: And now here's the thing: As you can see, this code implements a gravity flip: You touch an smb1 coin and your gravity flips, returning back to normal when you touch a ring. So far three things work: the player's sprite flipping upside down, inverted gravity, and being able to jump while touching the ceiling (but the last one is a bit bugged)
The only problem is that I can't get the player character to stand still in mid-air as if he was touching the ground. I already tried setting player offset 0x146 to 2 but that didn't seem to do anything. Any suggestions?

This isn't currently possible to do. It's a lot more complex than just that.

My suggestion for anti-gravity would be the following:

1) Make two versions of the level, one the right way up, one upside down, in separate sections.
2) When you want to flip gravity, move the player and all NPCs to the opposite section.
3) When in the reversed section, apply some code using LunaLua's Capture Buffers to flip the screen upside down.

That's what I feared. Well, thanks anyway.

I mean, you could spawn a block or NPC underneath the player, but that would affect other NPCs as well.

Yeah I realized that after replying to the other post. An npc with npcblock=0 and npcblocktop=0 wouldn't affect other npcs, right?

Possibly not, actually. Worth a try.

Hoeloe wrote:Possibly not, actually. Worth a try.

Well, npcblock=0 seems to work correctly.
But npcblocktop doesn't want to work. Npcs still stand on top of whatever it is. :C

Also, how can I show and hide layers? Everything I've tried doesn't seem to work

Use Layer.get(name) to get a layer by its name, and then use Layer:show(hideSmoke) and Layer:hide(ShowSmoke) (where ShowSmoke is a boolean, if it's true then there won't be any smoke).

That worked, thank you!

I found a way to attach it, but it's saying my board attachment quota has been reached. I haven't attached a single picture yet!!!!

Many people have told you how to upload pictures by using imgur and you also received a response from an Admin that the attachment quota likely won't be increased, so you should probably just listen to them. You've asked this question so many times and in the wrong spots, but never listened to anyone

I added the .lua, but I'm starting to feel something's up. I updated to 1.3.0.1, and it's notifying me of an attached lunalua. I only tried the level in the editor, but I have some suspicion that it's trying to indicate it will work if I play it in the actual game. I'm not trying it yet since my adventure isn't nearly done yet. Spoiler alert: I am currently working on world 4, and will upload the project when I finish that. The level with the problem is a ghost house serving as a transition between worlds and 4.

What's wrong with this? I pretty much mooched this code off of the documentation but I'm getting the error "unknown collider type":

Code: Select all

local colliders = API.load("colliders");
 
function onTick()
	for _, v in pairs(BGO.get(38)) do
        	if (colliders.collide(player, v)) then
           		player:kill();
        	end
		if (colliders.collide(npc, v)) then
			npc:kill(9);
			Audio.playSFX(16);
		end
    	end
end

Which line in lunadll.lua gives the error?

Where do you define the variable "npc"? If it's nil that may be causing that error.

Nm. Got it resolvedish

Note "lunadll" was changed to "lunadll.lua" at a later point.

What's your question then?

You have a LunaSavedVars file almost as new as the lunadll file, which implies that the script is being run and saving that.

Do you happen to have more than one onLoop() function? I think they will overwrite each other if you try to make more than one with the same name.


Edit: General question: What's the difference between API.load and the other API loading functions? API.load isn't mentioned at all on the wiki.
