Beam

Tue, 25 Jun 2024 01:48:37 UTC

Beam is a top down puzzle adventure and is meant to be mysterious, relaxing and pretty. If you get stuck read the signs around you! It is inspired by the Zelda series, Myst, The Witness, Tunic, Hyper Light Drifter,etc and is my first attempt at coding/game development. Feedback is very welcome!

Controls

Arrow keys move the player
O (z on the keyboard) various actions
X (x on the keyboard) run if unlocked

New additions in Beam2.0

Graphics updates

Altered some sprites and effects
Beams now continue to glow in lightning land
Beam colors are similar in day and night
Added bird reflections
Animated the door openings
Added an intro when first launching the overworld

Game updates

Birds now play a larger role in the narrative
Added a new area for bird lore
Reorganized some events to hopefully make the game more interesting and forgiving
Gated off the first task so it can be treated like a tutorial before you advance
Added an effect at the end to tie in the birds
Updated the water sparkles for more control
The map is significantly different
added bird idols and functionality
added a wave sound

Ongoing challenges

There is one area that if conditions are right the CPU overloads.
The music and sound effects sometimes clash and cancel each other out.

Variables as Function arguments

Wed, 07 Feb 2024 03:49:10 UTC

hello world.
I think I'm missing something in the custom function realm when it comes to using variables as arguments. I'm trying to pass in a variable that defines one of 6 beams to a function so I can use it for all of the beams but it does not seem to be working and I think I'm trying to do something that might not be allowed in Pico-8. For example I have a custom function to light up this beam and it works great:

..but I need to reuse this to do something similar for 5 more of these beams. I'd like to create a reusable function around the following as I am repeating code:

function beam_2()
if mg(35) and p.x<500
then
pal(5,7)
spr(35,384,328) sfx(0)
b2_charge=true
else b2_charge=false pal()
end
if b2_go==true then
pal(5,7)
spr(35,384,328)
pal()
end
end

I thought I could get away with using something like the below bm_chg function in place of the beam_2 function but it does not seem to be passing the b2_charge variable when I input it for chg_var.

function bm_chg(sp,sx,sy,sc,chg_var,go_var)

if mg(sp) and p.x<96 then

pal(sc,7)
spr(sp,sx,sy) sfx(0)
chg_var=true

else chg_var=false pal()

end

if go_var==true then
pal(sc,7)
spr(sp,sx,sy)
pal()
end

end

I was unable to find any documentation of exactly how this works in the manual and any help would be greatly appreciated.

Animation speed resetting after loop

Wed, 13 Dec 2023 02:40:15 UTC

I'm hoping someone out there can help me solve the ever increasing speed of my bird animation. The goal is to have the ability to put these bird sprites (spr 39 is the static resting bird sprite) all over the map and as the player gets close to them they are disturbed and fly away. A counter ("birds") counts them and this counter is used to alter states later in the game. Everything is working except that every bird that is disturbed flaps it's wings faster than the previous bird. Any attempt to reset this just results in the bird not animating at all and floating away motionless which is kind of comical. :P

My update and draw code for these bad bois are below. Any ideas as to how I could get them to fly away at the same animation speed regardless of how many have been disturbed? Newish to coding in general here so I'm probably going about this the wrong way. FYI, sprite 39 and 19 are both static versions of the bird depending on the background they sit in front of.

--birds--

function u_bird()
-- btimer=0

for y = flr(p.y/8)-1,flr(p.y/8)+1 do
for x = flr(p.x/8)-1,flr(p.x/8)+1 do

if mget(x,y)==39 or mget(x,y)==19 then
add(fly,{
ex=x8,
ey=y8,
sp=39,
})
if mget(x,y)==39 then
mset(x,y,59)
elseif mget(x,y)==19 then
mset(x,y,38)
end

birds+=1
end
end
end

for e in all(fly) do

e.ey-=.5
e.ex+=.2
e.sp=birdsp

if birdsp<43.9 and birdsp>=40.1 then
birdsp+=.1
else
birdsp=40.1
end
end
end

function d_bird()

for e in all(fly) do
spr(birdsp,e.ex,e.ey)
end

end

jittery player sadness

I'm new to PICO-8 here folks but absolutely hooked! I'm having a problem with my player shaking during movement as well as getting caught on my flagged sprites that the player collides with. I know some basics and have compiled this code by watching tutorials and scanning forums for code snippets but I think I am mixing some things that don't play well. I am really going for a smooth player movement vibe so I just added some acceleration rather than an abrupt "p.x+=1" movement style. It doesn't appear to show in my GIF but the player shakes violently during gameplay. Any ideas as to what could be causing this would be greatly appreciated!
