r/pico8

so I'm currently working on an attack and want to make it so that even when I'm moving I am slashing the sword in any key I'm holding in and should rotate in that key because I'm not making a sprite for each direction, here's my attack code:

--attack

--attack variables
atck_strength = 5
atck_dur = 4
is_atck = false
atck_swing_anim_timer = 0
atck_delay = 2

function attack_init()
atckposx = 63
atckposy = 63
end

function attack_update()

 if btnp(🅾️) then
  is_atck = true
  atck_swing_anim_timer = atck_dur
 end

 if atck_swing_anim_timer > 0 then
  atck_swing_anim_timer -= 1
 else
  is_atck = false
 end

end

function attack_draw()

if is_atck then
spr(001, atckposx, atckposy)
end

end

A small piece of architecture for PICO-8, it is a strong requirement for the project I'm working at.

I'm struggling on making a dash, I've tried everything but they just broke the game, here's my code:

--puppy killer

--by roastedbird

function _init()

--player variables

`posx = 0`

`posy = 0`

`speed = 1.5`

`dash_speed = 3`

`dash_dur = 8`

end

function _update()

--input

`if btn(➡️) then`

 `posx = posx + speed`

`end`



`if btn(⬅️) then`

 `posx = posx - speed`

`end`



`if btn(⬆️) then`

 `posy = posy - speed`

`end`



`if btn(⬇️) then`

 `posy = posy + speed`

`end`

end

function _draw()

`cls()`

`spr(0, posx, posy)`

end

What started out as a mock-up screen is now becoming a reality :)

Does anyone know if it would be possible to mod a game tank to run Pico 8 or Pico Tron?

so for context i ordered my first board raspberry pi pico 2, then i saw its impossible to run pico 8 on it without PSRAM, So i was wondering, can Raspberry pi zero 2 handle it? or Seeed Studio XIAO ESP32S3 Sense?

Just getting started with the Pico-8. Thought I'd try a port of Bubble Universe first...

Controls

• Use the arrow keys to move around.
• Use Z and X to zoom in and out.

Hold both Z and X together then...

• Use Left and Right to adjust the speed of the animation.
• Press Down to pause and resume the animation
• Press Up to reset everything

Based on an algorithm by yuruyurau https://x.com/yuruyurau/status/1226846058728177665

It's the basis of making a simple star field.

I create an array for an individual star (star), then an array of those arrays (stars). I use a loop to set the individual values for each star, and (for debugging) print out the values. They're different as expected. But immediately afterwards, they all become the same value - the value of the last item added.

Here's the output:

-0.6718
-0.5777
0.0473
-0.2585
0.6657
-0.0112
-0.392
-0.5346

-0.392
-0.5346
-0.392
-0.5346
-0.392
-0.5346
-0.392
-0.5346

And here's the code ...

function _init()
 star={0,0,0,0,0}
 stars={}
 numstars=4

 -- populate the array
 for c=1,numstars do
  add(stars,star)
 end

 -- create all the stars
 initstars()
end

function initstars()
 for s=1,numstars do
  initstar(s)
 end

 -- for debugging, now show the x inc and y inc values for all the stars
 print("")
 for s=1,numstars do
  print(stars[s][4])
  print(stars[s][5])
 end
end

function initstar(s)
 local ang=rnd(1)
 local spd=rnd(1)

 stars[s][1]=64 -- x
 stars[s][2]=64 -- y
 stars[s][3]=0  -- colour
 stars[s][4]=cos(ang)*spd  -- x inc
 stars[s][5]=sin(ang)*spd  -- y inc

 -- for debugging, print out the x inc and y inc values
 print(stars[s][4])
 print(stars[s][5])
end

After many still open projects and prototypes created on our wonderful fantasy console, is time to commit to a project I've always willing to create, a monster taming videogame.

I'm not looking for any viral/commercial success of course, just looking for the reward of sharing my progress across PICO-8 communities and gather valuable feedback that could polish the idea as I'm closing milestones.

I'm working on a Spanish fantasy console devs community on Youtube, feel free to reach me in case you are interested.

Thank you!
