Hi! I'm attempting to build my first game using PICO-8 and am having some trouble with finding an online tutorial for this specific issue.

I'm looking for a simple function that will help make a defined object spawn periodically according to a timer. I've created a moving sprite and a frame counter that counts to 600 and repeats, and I'd like to have a specific enemy spawn on frame 600, instead of just spawning at the RUN command. Any suggestions?

I've included my code below, but it's admittedly very messy, as this is my first experience with programming outside of HTML. Also, if it's out of line to just hop on the forum and start pleading for help, let me know too! :P

This has happened a couple times and I was hoping it would just fix itself but it never seems to.

My browser does a pretty good job of keeping me logged in here on the forum, but every now and then it logs me out - which is fine, I understand how and why that happens.

But then once I'm logged out, I can't log back in with my password. I always have to login by email. Granted, this works, but then there's no purpose of having a password.

Even if I change my password on my profile, it will not allow me to log in.

Has anyone else experience this or am I on an island with this one?

If it's just me, then it's just me but wanted to call it out if it's something others have seen as well.

What am I doing wrong? I'm sure I'm being dumb.

I can go down ladders fine, but not up them.

Hi guys, I'm currently working on a top-down turn based rogue like. The camera follows the player (or enemy) around - whichever actor's turn it is. When it is the player's turn, I would like to display text as a menu but also have the camera above the player. Is there a way to print text without it being effected by the camera offset? Or should I be negating the offset with my print x/y co-ordinates?

A snippet of my player's draw function (called by function _draw())

function player:draw()
 --centre camera if it is the player's turn
 if actor_index == 1 then
  camera(self.x * 8 - 64, self.y * 8 - 64)	
 end

 -- draw the player
 spr(0,self.x * 8, self.y * 8) 

 textanimcolour += 1
 if textanimcolour > 15 then textanimcolour = 0 end

  if actor_index == 1 then

   --if we are in the move_or_action state, draw the menu as well.
   if self.state == "move_or_action" then
   --recentre camera
   camera()
   --draw the menu
   local yoffset = 80

--move_or_action_menu is an array of strings
   for i=1, #move_or_action_menu do
    local text_col = 5
    if i == self.menu_selection then text_col = textanimcolour end
    print(move_or_action_menu[i], 10, yoffset, text_col)
    yoffset += 10
   end
  end
 end

Feature request: a _pause() callback that is triggered just before the pause menu is displayed. This would give those of us who are using menuitem() a convenient way of doing a little preparation beforehand. I have a particular case where the contents of the menu may change depending on when it is opened.

As much as I hate to break things once people have gotten used to doing them a certain way, there's a keyboard inconsistency in the code editor while running under OS X that really messed with me early on, and continues to do so here and there.

fn+left/right - takes you to the very beginning or very end of a line
fn+up/down - instead of taking you to the beginning/end of the document, results only in page up/down

command+left/right - takes you to the next symbol/token/whatever.
command+up/down - instead of page up/down (what I would expect), takes you to beginning/end of document

It seems to me that the command key should control the shorter movements, while fn should be reserved for the extreme beginning/end jumps.

UPDATE: Today is monday the 16th.

Now leeches are one solid creature, and the camera follows their head.

Press z to lock/unlock cam.
Press x to randomise leech (only 3 breeds atm)

You can change the variable BORD to change the border size.
If you wanted, you could probably figure out how to add a new leech breed.

5 days until the deadline.

first post.
eventually this will be a virtual pet game.
I'm making it for the winter 2017 my first game jam on itch.

gradually getting my head around lua.

Hey All,

First post here after recently picking up and playing with pico-8 (humble bundle). It's rather brilliant I have to say!

I have only been playing around with coding for a couple of months and remain very much a novice, and this is my first time using lua with pico-8.

My question is regarding tables of tables (objects I am spawning in my game), and the deletion of those objects...

Let's say we have the following little program which spawns 5 THINGS, gives them unique names, and then adds them to the list a{}. We then delete the item with NAME=3, and then print some output...

a = {}

for i=1,5 do
	local thing = {}
	thing.name = i
	add(a,thing)
end

for thing in all(a) do
 if thing.name == 3 then
  del(a,thing)
 end
end

for thing in all(a) do
 print(thing.name)
end

print("# = "..#a)
print(a[3])

Output is: 1, 2, 4, 5, # = 4, TABLE

This works fine, and is the standard practice I have been using to remove objects from the master table.

However, let's say I already know which item on the main table (a) that I want to delete by its index, say the third item... i.e. a[3]

Combat Tanks 0.1

The beginning of an attempt to recreate "Combat" from the Atari 2600.

Tanks and movement only at this point. No bullets or collisions yet.

A lot of the code was borrowed from "Blasteroids" by Lulu Blue as detailed in Pico Zine #3.

When I try to run the code listed below, my game freezes because of the while loop. Can anyone shed some light on how I can prevent the while loop in this code snippet from choking? Or if there's a better way all together?

I'm hoping to add additional objects to these functions (though they would be single objects instead of sets of 30 and 15, but I'm not at all an experienced coder.

I was trying to borrow code from the following page: https://level0gamedev.blogspot.com/2016/05/back-to-game-code.html

I'm also having a second issue of all 45 sprites being set to foo's sprite instead of 30 for foo and 15 for bar, but i'll have to tackle that later unless someone can weigh in on that as well.

Any help is greatly appreciated! Thank you :)

function _init()
test = 0

for i = 1, 30 do
	spawn_actor(foo)
end

for i = 1, 15 do
	spawn_actor(bar)
end	

function spawn_actor(name)
	local obj = {}

	obj.type = name
	obj.frame = nil
	obj.x = flr(rnd(right_border) + left_border)
	obj.y = flr(rnd(bottom_border - top_border) + top_border)
	obj.w = 8
	obj.h = 8
	obj.x2 = obj.x + obj.w * 8
	obj.y2 = obj.y + obj.h * 8

	if obj.name == foo then
		obj.frame = 16 + flr(rnd(3))
	elseif obj.name == bar then
		obj.frame = 32
	end

	overlapped = true
		while overlapped do
		overlapped = false
		foreach(actors, function(actors)
			if actors.x <= obj.x + obj.w * 8 + 1 and 
			actors.x + actors.w * 8 >= obj.x - 1 and 
			actors.y <= obj.y + obj.h * 8 + 1 and 
			actors.y + actors.h * 8 >= obj.y - 1 then
				test += 1
				overlapped = true
				obj.x = flr(rnd(right_border) + left_border)
				obj.y = flr(rnd(bottom_border - top_border) + top_border)
			end
		end)
	end
	add(actors, obj)
end

	cls()
	foreach (actors, draw_actor)
end

function draw_actor(obj)
	spr(obj.frame, obj.x, obj.y, 1, 1)
