Code: Select all

local frameNum_ssj0 = 1

-- somewhere for rendering
Graphics.draw(ssj0[frameNum_ssj0], X1, Y1, 5)
frameNum_ssj0 = frameNum_ssj0 + 1
if frameNum_ssj0 > #ssj0 then
    frameNum_ssj0 = 1
end

I hope it makes somewhat sense for you

Angelus wrote:Hello there, I've been trying to use LunaLua for custom music and while it works pretty well for most of the time, I'm facing a little problem here:
I know how to set the music to play into a specific event, but I would like to know how to make it stop after a posterior event, replacing it by silence. The problem is, all my attempts have failed since the music just start over again when I expected it to stop playing. Here's the code I have so far. Am I doing something wrong?

Spoiler: show

play = false

function onLoop()
if play then
Audio.SeizeStream(1.14)
Audio.MusicOpen("1 - 1 Boss.ogg")
Audio.MusicPlay()
end
end

function onEvent(eventname)
if eventname == "Cutscene 4 - 15" then
play = true
else
if eventname == "Cutscene 5 - 1" then
play = false
Audio.ReleaseStream(1.14)
end
end

So the best option if the animations doesn't work is to remake the graphics into seperate files for each frame? If there isn't any other options... I'll try it.

local img = Graphics.loadImage("img.png")

function onDraw()
	Graphics.drawImageToSceneWP(img, x, y, xOffset, yOffset, width, height, priority)
end

function onDraw()
	Graphics.drawImageToSceneWP(img, x, y, 0, yOffset, 64, 64, priority)
end

function onDraw()
	t = (t + 1)%8 --%8 makes sure we cycle from 0 to 7.
	Graphics.drawImageToSceneWP(img, x, y, 0, 64 * t, 64, 64, priority)
end

No. Take a look at how SMBX itself organises its spritesheets.

Given this is a custom sprite, it can be displayed like this:

Code: Select all

local img = Graphics.loadImage("img.png")

function onDraw()
	Graphics.drawImageToSceneWP(img, x, y, xOffset, yOffset, width, height, priority)
end

xOffset and yOffset are the top left coordinates of the displayed frame of the spritesheet.
width and height are the dimensions for the drawn frame.
There are 8 frames on this sheet, of 64x64 pixels in size. The xOffset for the frames never changes, either, so we can put 0 for that:

Code: Select all

function onDraw()
	Graphics.drawImageToSceneWP(img, x, y, 0, yOffset, 64, 64, priority)
end

yOffset is a variable which changes depending on the frame you want to display. The most rudimental way to do an 8 frame animation is just to have a timer run through:
local t = 0

Code: Select all

function onDraw()
	t = (t + 1)%8 --%8 makes sure we cycle from 0 to 7.
	Graphics.drawImageToSceneWP(img, x, y, 0, 64 * t, 64, 64, priority)
end

This makes the frame switch every frame, but to circumvent that you can easily slow down the timer and floor it.

Enjl and the other people who helped me, thank you very much!

for k,v in pairs(Block.get()) do
--if it is nothing then spawn sth

Enjl wrote:That won't work. Instead, pick spawn coordinates and after that do a getIntersecting check around that box and spawn the NPC only if the returned list is empty:

local spawnX, spawnY = rng.random(a,b), rng.random(c,d)
local collidingBlocks = Block.getIntersecting(spawnX - 16, spawnY - 16, spawnX + 16, spawnY + 16)
if #collidingBlocks == 0 then
local spawnedNPC = NPC.spawn(id, spawnX, spawnY, section, false, true)
