How to do a level timer?

Except use API.load instead of loadAPI and function onStart() instead of function onLoad()

And, how do I make the coins collected by a player just continually increase, without giving the player a 1-up and resetting to 0 when it hits 100 coins, and have this show up on the HUD?

I suggest you to read error message's description.

Code: Select all

VB6 Error Code: 9
VB6 Error Name: Subscript out of range
This happens when too many items are in the scenery.

The fun thing was there was almost nothing in scenery (only black background from SMB3 exit)

I'm trying to get rain particles to work; the code I have right here doesn't work.

Code: Select all

local particles = loadAPI("particles");
 
local effect = particles.Emitter(0, 0, Misc.resolveFile("p_rain.ini"));
effect:AttachToCamera(Camera.get()[1]);
 
function onCameraUpdate()
    effect:Draw();
end

And yes, I do have the .ini file in the level folder.

Scenery refers to the canvas, or the screen. Subscript out of range triggers when any limit in SMBX is reached. Be it blocks, warps, npcs or even sizeables.

It should? Can I see the contents of the ini file? (also use API.load)

Code: Select all

grad_1={0,0.2,1},{0,1,0}
colTime={0,0.5,1},{0xFFFFFF00,0xFFFFFF99,0xFFFFFF00}
limit=1000
rate=500:2000
xOffset=-800:800
yOffset=-600:600
rotation=40:45
speedX=-300:-600
speedY=100:1000
height=8:32
width=1
scale=1
lifetime=1

The .ini file is located in the same folder as the code.

Hello!
So I decided to download LunaLua too... but when I wanted to test my level I got this error message:

Spoiler: show

Version of PGE is 0.3.1.8

Thanks for the help!

You aren't loading any sprites through the ini file.

Yeah, I got that. I added the line "Texture=Particle.png"
(and yeah I do have a PNG file named Particle in the folder)

Don't use the PGE Engine for testing. You have to still use the SMBX Engine for testing.

texture shouldn't be capitalised.

This still doesn't seem to work.

Can I make an npc transform on a mem function?

Let's say if I wanted a Thwomp to transform into a friendly coin when it hits the ground.

No need for mem offsets.

Okay. So I'm working with this code:

Code: Select all

storedpower = false

function onTick()
	if player.powerup ~= PLAYER_SMALL or player.powerup ~= PLAYER_BIG then
		storedpower = true
	end
	
	if player.powerup == PLAYER_SMALL then
		if storedpower == true then
			player.powerup = PLAYER_BIG
			storedpower = false
		end
	end
end

It pretty much does what I want it to (functions like the NSMB power-up system), but when the player is hit, for the duration of the time the powerdown effect is triggered, the player moves down (into the ground) as the sound plays, eventually resulting in the player's death; how can I avoid this?

There's an offset for forced animation states, such as powerup and powerdown. You're setting the player to big every frame during this animation while he's still considered small.
