TRUE. I did make the docs after reading this post because I thought they might help, and forgot to link them once I was done haha.

(kidding of course, the docs are actually pretty good atm)

I haven't been here in a while but I'm looking for a way to stop Link from being able to bounce on spikes. Not great at lua but thought there must be a way better than mine which was putting collider boxes a touch above spikes to harm the player.

technically you don't need any custom lua for that. there's already block 672 which is a solid hurt block that link cannot bounce off.
i guess a slightly cleaner solution if you absolutely need to use the vanilla spikes would be to make a custom block that mimics them? i don't know of a documented memory offset that lets you control link's down stab (and even if there was it would probably make you unable to down stab npcs as well, and i assume you don't want that)

Never thought about using the hurt block. I could try that instead of some lua solution. Thanks.

Any way I could make an NPC chase the player?

Just along the ground, not in the sky as if it were a parakoopa, I mean.

Added in 2 hours 19 minutes 5 seconds:
In this case, I have a JSON field for all NPCs:

Code: Select all

		{
			"control": "checkbox",
			"name": "chasesMe",
			"title": "Chase Player?",
			"tooltip": "Do you chase the player?",
			"value-default": false
		}

So now, the game is intended to override the NPCs current speed and direction with this:

Code: Select all

function onStart()
	Hostiles = NPC.get()
end
function onTick()
-- Chase Player --
	for k,v in ipairs(Hostiles) do
		if v.data._settings._global.chasesMe then
    		local cx = v.x + 0.5 * v.width
    		local p = player
    		local d = -vector(v.x - p.x + p.width):normalize() * 0.1
    		local speed = NPC.config[v.id].speed
    	v.speedX = v.speedX + d.x * NPC.config[v.id].speed
    	v.speedX = math.clamp(v.speedX, -4, 4)
    end
    end
end

Okay, so I just updated it so that the NPC follows the player.

Code: Select all

function onTick()
Hostiles = NPC.get()
-- Chase Player --
	for k,v in ipairs(Hostiles) do
		if v.data._settings._global.chasesMe then
			Text.print(Distance, 70, 70)
			Text.print(v.direction, 70, 90)
			closeplayer = Player.getNearest(v.x,v.y)
    		Distance = closeplayer.x - v.x
    		if Distance < 0 then
    			v.direction = -1
    		end
    		if Distance >= 0 then
    			v.direction = 1
    		end
    	end
    end
end

Problem is, they'll change direction initially, but if you go past them, they don't change direction. I'm not sure, but they seem to remain going in one direction regardless.

I'm having two problems setting up my custom HUD.
1. I can't remove the weird 2-pixel spacing between numbers
2. For some reason, the coin counter uses vanilla graphics for its numbers despite the fact I have replaced the hardcoded number graphics with SMB3 style ones in my episode folder

Basically, right now it looks like this:

but I want it to look like this:

Hoping this won't be too difficult to fix.

Create folder called "textplus" and then another folder inside it "font"
then copy 1.png from "SMBX2 > data > scripts > textplus > font" and then you can edit it

Thanks, this does the trick perfectly for the coins. Now, if only I could also remove the spacing in the lives/stars counters or replace those with textplus font1 as well. Afaik, there is nothing in huboberride.lua that determines which counters are displayed as textplus, so this is probably not going to be easy to solve.

I'm trying to make a layer disappear but it's not working.

Code: Select all

for k,w in ipairs(Layer.get("WallsafeLock")) do
			w:hide(false)
		end

What am I doing wrong? The event that would normally hide the layer occurs just fine so something's wrong with the layer visibility command I guess.

Posted: **Sat Aug 20, 2022 12:01 am**

https://docs.codehaus.moe/#/reference/layer
Layer.get(name) returns the layer with that name, not a list of layers. Store it into a local variable and call :hide() on that local variable. No need for a for loop.

A quick question - is it possible to modify the game's slippery/ice physics? I'd like to change the acceleration/deceleration properties of slippery blocks to better fit Enjl's playerphysicspatch.lua, if possible.

Question,

Is there a way to call a random variable everytime a new episode is started?
This is to give a certain item a randomized location and give the game some replay value.

Like this,
Upon starting a game in the episode, var will randomly equal 1, 2, or 3.
if var = 1:
Item goes to level 1 as opposed to level 2 or level 3
if var = 2:
item goes to level 2 as opposed to level 1 or level 3
if var = 3:
item goes to level 3 as opposed to level 1 or level 2

Oh, I know how to use a random variable, calling it when the episode first starts is the thing, like maybe when the overworld loads for the first time and then done.

Although, I guess I can also load a random global variable to save on the intro level. Maybe that'll be easier.

if you do use an overworld, putting this in your map.lua should do the trick:

Code: Select all

function onStart()
	if(SaveData.randomGlobalVar == nil) then
		SaveData.randomGlobalVar = RNG.randomInt(1, 3)
	end
end

then, you can spawn items accordingly by checking in each level's luna.lua:

Code: Select all

function onStart()
	local seekValue = 1 -- value corresponding to this level
	if(SaveData.randomGlobalVar == seekValue) then
		-- do stuff here
	end
end

Is there a way to trigger an event upon warping through a specific door?

Or at least manually trigger a warp upon an event occurring?

Okay, here's another question.

I put various image files into another folder within my episode folder to make a less crowded library. The thing is,
Item = Graphics.loadImage(Misc.resolveFile("MyItem.png")) returns an error message. Isn't the resolve supposed to load this folder on its own?

Is there something I should add the Graphics.loadImage command?

it's always best to read the fine print. resolveFile won't look absolutely everywhere, and has a strictly defined search pattern. if the file is in an arbitrary folder, you have to also include the folder name:

Code: Select all

Graphics.loadImage(Misc.resolveFile("Folder/MyItem.png"))

however, if the lua file itself is right in your episode folder too (as opposed to a level's custom folder), the resolveFile() call is superfluous and can be removed:

Code: Select all

Graphics.loadImage("Folder/MyItem.png")
