Once you reach a checkpoint the "global value" gets changed and because different layers get hidden or shown, it would mean the player would get teleported to the "last reached" checkpoint.

In case context is needed: I try to integrate some kind of "fake checkpoints" (without powerup and sfx).
At the beginning of the level a fake loading screen is visible (works fine, not the problem here) and after a bunch of seconds the player is supposed to get warped to the last "checkpoint". HOWEVER I need a variable which does store the right and last value instead to reset every time after the player death.
Since this should work like in the origional SMB without savepoints and worldmap I need a variable which does save after player death.
I want to use GameData because if you close SMBX you have to restart with the first level
(I plan to use Auto-loading next level after winning • levellist.lua
myGameData or levelstartwarp could be used beyond the corresponding level as follows.
World 1-1: Player reaches first "checkpoint" -> Value: 1
player dies
Value stays 1
player restarts at last checkpoint
player dies (before next checkpoint)
Value stays 1, no progress of the player
player reaches second "Checkpoint" -> Value: 2
Player reaches World 1-2 (Value for safety reasons: 3)
player dies
Value still 3, player restarts from levelstart of World 1-2
player reaches first "Checkpoint" (of 1-2): Value 4
player dies
player restarts at last checkpoint (first one of 1-2)
...
I think you get it now

I am honest: I do not really know what I am doing here. I barely understood some basic things from the Demolevels and and try to find the grain here like a blind hen. I hope that by showing something here, someone will be willing to tell me how it works. These documentaries are a bit difficult for people like me to understand. I'm not really the scripting type (never have been in my life).

local Routine = API.load("Routine")
local inputs2 = API.load("inputs2")
local test = 0

function onStart()
local defaultLayer = Layer.get("Default")
defaultLayer:show(true)
local lvlstartLayer = Layer.get("LevelScreenPlattform")
lvlstartLayer:show(true)
end

function onTick()
Text.print(test, 100, 100)

if player.y < -180032 and player.section == 0 then
Routine.run(levelStartScreen)
end

if player.section == 1 then
Routine.run(IncreaseCounter)

end
end

function levelStartScreen()
local lvlstartLayer = Layer.get("LevelScreenPlattform")
inputs2.locked[1].all = true
player.speedX = 0
lvlstartLayer.speedY = 2.5
Routine.waitFrames(200)
lvlstartLayer.speedY = 0
inputs2.locked[1].all = false
end

function IncreaseCounter()
if test ==0 then
test = test +1
end

if you wanna remove powerups and sounds from checkpoints you can just do that

function onStart()
for k,v in ipairs(NPC.get({400, 430}) do
v.data._basegame.checkpoint.sound = nil
v.data._basegame.checkpoint.powerup = nil
end
end

or you can load the checkpoints library

local checkpoints = require("checkpoints")
local cp1 = checkpoints.create{x = 400, y = 300, section = 1}

-- collect it with onEvent for example
function onEvent(eventName)
if eventName == "collectCP1" then
cp1:collect()
end
end

-- you can also check starting cp in onStart
function onStart()
local c = checkpoints.getActive()
if c == cp1 then -- if the player starts at cp1
Layer.get("AAAA"):show(true)
end
end

My recommendation would be to not do that whole thing as a section but instead as a routine run in onStart and a png overlay.
With a bit of finagling you can offload this routine into a library too and automatically apply it to every level without having to copy that section setup everywhere. But copypasting the code is also fine and still saves a lot of time and trouble.

Code: Select all

local introImg = Graphics.loadImage("intro.png")
local showingIntro = true

local function introRoutine()
	Audio.SeizeStream(player.section)
	Audio.MusicPause()
	Misc.pause()
	Routine.waitSeconds(3, true) -- true makes it advance while paused
	Misc.unpause()
	showingIntro = false
	Audio.MusicResume()
	Audio.ReleaseStream(player.section)
end

function onStart()
	Routine.run(introRoutine)
end

function onDraw()
	if showingIntro then
		Graphics.drawImageWP(intro, 0, 0, 10)
	end
end

I don't consider myself a coder "type" either I've just been at it for a decade.

for k,v in ipairs(NPC.get({400, 430})) do
	v.data._basegame.checkpoint.sound = nil
	v.data._basegame.checkpoint.powerup = nil
	end

By varying the parameters across frames, animation can be created.

Something you can do is stack the frames vertically like blocks, npcs and other SMBX assets do, and then use a timer to "vary parameters across frames".

But before I get to that I recommend we get rid of the black on the image and instead render it separately, because that part doesn't animate. Then your image can be less tall. Then, let's say you have a 4-frame image, your new onDraw wouild look something like this:

Code: Select all

function onDraw()
	if showingIntro then
		-- this just draws a black overlay
		Graphics.drawScreen{color = Color.black, priority = 10}
		
		-- breaking down the draw process step by step
		local imgWidth = introImg.width
		local frames = 4
		local framespeed = 8
		local imgHeight = introImg.height / frames
		-- this next line makes the drawtime timer 8x slower than it usually is, eliminates any resulting decimal numbers from the division, and makes sure the frames properly loop by taking it % frames (so the output is 0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,0,0,0,0,... and so forth)
		local frame = math.floor(lunatime.drawtime() / framespeed) % frames
		-- Graphics.drawImageWP(image, x, y, sourceX, sourceY, sourceWidth, sourceHeight, priority)
		-- The math in the x and y effectively centers the image to the screen
		-- The math for sourceY offsets the drawn section of the image by the current frame times the number of pixels in height. This is how you create a frame animation
		Graphics.drawImageWP(introImg, 400 - 0.5 * imgWidth, 300 - 0.5 * imgHeight, 0, imgHeight * frame, imgWidth, imgHeight, 10)
	end
end

Just realized: Removing the black background did not make any sense, considering I used these white double boarders, but whatever.
It was not a big deal anyway, since I used a lot of layers. :mrgreen:

My mistake. I mixed up drawtick and drawtime. Replace drawtime with drawtick.
For reference, drawtime is measured in seconds, drawtick in frames. So right now you would see it animate after 8 seconds pass lol.

You could also render the double white border separately with a second drawImage call and a second image with just one frame.
