What am I doing wrong? I'm sure I'm being dumb.
I can go down ladders fine, but not up them.
Cartridge
Code
function _init()
p={x=0,y=0,spr=0}
end
function _update()
if(btn(0)) then
p.x-=1 -- left
end
if(btn(1)) then
p.x+=1 -- right
end
-- ladder down
if (btn(3) and fget(below)==2) then
p.y+=1
end
-- ladder above
[b]if (btn(2) and fget(above)==2) then[/b]
p.y-=1
end
end
function _draw()
cls()
map(0,0,0,0,6,6)
spr(p.spr,p.x,p.y,1,1)
below=fget(mget(flr(p.x/8),flr(p.y/8+1)))
[b]above=fget(mget(flr(p.x/8),flr(p.y/8-1)))[/b]
behind=fget(mget(flr(p.x/8),flr(p.y/8)))
print ("behind "..fget(behind),90,100)
print ("below "..fget(below),90,110)
print ("above "..fget(above),90,120)
end

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]

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.

Just a little procrastination project. Not sure if it's going anywhere. Very early demo just showing movement and tiles. |

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
function _draw()
cls()
foreach (actors, draw_actor)
end
function draw_actor(obj)
spr(obj.frame, obj.x, obj.y, 1, 1)
end

This is just a slightly modified version of one of the example programs from the official guide found here. This is the first thing I've made with PICO-8 after picking it up in the humble bundle. Enjoy! :)
Edit: Oh TW for flashing colors and stuff.

Hello everyone, this is just a small thing I did for Pixel Dailes.
Controls :
- Left/Right : Move cursor.
I didn't do anything else than just this screen, I was mostly interested in throwing the bases. I might touch it up later but that's unprobably (unless people are interested in working on it together...)
(Older version, music-less)
Have a nice day!
