So I have another question.

How would I go about making a custom animation for an enemy grabbing the player after charging into them? I guess the idea would be to (1) set the player state to invisible and making a custom graphic for the npc to transform into depicting them grabbing the player and then end the scene and set the player back to normal? Or maybe (2) make a custom graphic sheet depicting the player getting grabbed and find a way to make it look like the enemy is strangling them or something.

If you could provide any advice about how I would do this, I'd appreciate it!

Anyone know how I'd add custom world music?

I'm doing the thing with music.ini and the visible file name (not in another folder) but when I play the song in the music box section in the world map editor, it's still the same vanilla song.

[world-music-1]
name="MY WORLD Overwold"
file="MySong.mp3"

What am I doing wrong?

Have you tried it in the actual SMBX engine? It should work there.

You mean, switching the music out in the main music file that will change it for the other episodes? Or is there some other engine thing?

Oh wait, you mean outside of the editor. I'll try that.

Another thing,

Do instant warp exits not work with warping to a map location? Because when I reach an instant warp that would warp to a given location on the world map, nothing happens.

Looks like they don't. Try it with a portal warp. Alternatively, just stick in a door or a pipe or something.

How do I get npc-310 working? This is probably a dumb question but I dont know this. And yes before you ask, I've looked in the handbook and there is nothing :P

this isn't really a lua question, star coins are vanilla in SMBX2. just set it's index in the "item properties" tab on the right (starting from 1 and incrementing by 1 with each additional coin). while there's nothing in the handbook, this is very clearly explained by the tooltip that pops up when you hover over it in the editor.

I have tried that but it doesn't seem to work for me. Whenever I reload the level, load up another level or test the game the index gets set to 0...I'm not sure what I'm supposed to do. Am I supposed to choose the index while PLACING the coin because mine are all stuck at 0?

ideally you would, but right clicking it and setting the index from there works for me too.

Surprising. That's what I've been trying and it doesn't work for me unfortunately...I think I've found a bug.

How I can change the health of an npc and make them resist more hits?

There's two ways:

1. Alter their health using an NPC text file, which you can create using PGE. This only works for NPCs that already take multiple hits.

2. Use LightHitPoint.lua. It requires that you register the NPCs that you want to take extra hits in your luna.lua, and any NPCs who already take multiple hits will only take those hits once the health bar is empty.

There's a third way - write your own.

Code: Select all

function onNPCHarm(eventObj, harmedNPC, harmReason)
	if harmReason == HARM_TYPE_JUMP and harmedNPC.id == 1 then
		if harmedNPC.data.hp == nil then
			harmedNPC.data.hp = 3
		end
		harmedNPC.data.hp = harmedNPC.data.hp - 1
		if harmedNPC.data.hp > 0 then
			eventObj.cancelled = true
		end
	end
end
This, for instance, cancels any jump damage dealt to a goomba for 2 hits, granting it 3 hp.
It's basically what LightHitPoint already does, but I figured I'd write up this sample in case you wanted a bit more insight.

Hello, How do you activate an event in Lua?

As in:

Code: Select all

if number == 1 then

What code runs an event in the classic events.

I'm sorry if I'm not making any sense...
