I'm a big fan of this song and wanted to improve my PICO-8 music-making skills, so decided to remix it here.

Not 100% finished, but you get the idea.

I have been experimenting with player movement for a top-down 2D game. At the moment, I have "fixed" diagonal movement to be 0.7x the speed of straight-line movement, and also added friction so the character sprite slows down gradually.

The next step however is acceleration.

I'm wondering how a slow ramp into movement (acceleration) might be achieved using the lerping algorithm as introduced here: https://demoman.net/?a=animation-code-part-1

Does anyone have tips or a tutorial on how I could achieve this acceleration/deceleration??

Code for movement:

if (btn(➡️) and btn(⬆️)) then
        p.dx=p.speed*.707
        p.dy=0-(p.speed*.707)
    elseif (btn(➡️) and btn(⬇️)) then
        p.dx=p.speed*.707
        p.dy=p.speed*.707
    elseif (btn(⬅️) and btn(⬇️)) then
        p.dx=0-(p.speed*.707)
        p.dy=p.speed*.707
    elseif (btn(⬅️) and btn(⬆️)) then
        p.dx=0-(p.speed*.707)
        p.dy=0-(p.speed*.707)
    elseif (btn(⬆️)) then
        p.dy=0-p.speed
    elseif (btn(➡️)) then
        p.dx=p.speed
    elseif (btn(⬇️)) then
        p.dy=p.speed
    elseif (btn(⬅️)) then
        p.dx=0-p.speed
    end

 if not btnp(⬆️) and not btnp(⬇️) then
  p.dy*=friction
  if p.dy<0.01 and p.dy>-0.01 then
    p.dy=0
    end
 end
 if not btnp(➡️) and not btnp(⬅️) then
  p.dx*=friction
  if p.dx<0.01 and p.dx>-0.01 then
   p.dx=0
  end
 end

 p.x+=p.dx
 p.y+=p.dy
 p.x=mid(0,p.x,124) 
 p.y=mid(0,p.y,124)

Hello everyone!

Today I am sharing the results of a personal "game jam" I completed this weekend. I use the inverted commas there because I was very sporadic in terms of my time on the game jam, maybe averaging 4 hours each day... so in reality, I completed this game in about 8 hours.

This was my first proper dive into game programming, and, as a reflection of the project, I'm ecstatic that I was able to get a game made to this level in the amount of time I spent making it.

Things I want to implement next time

  • levels
  • different mobs
  • player lives

Some issues/questions I still have

  • I don't fully understand what code should be in _update() and _draw() (that is -- I don't know how or why I should separate code between these two functions.)
  • I don't know how to rotate sprites. I wanted to have the character rotate without having to create a different sprite set.
  • I didn't figure out how to reduce speed when travelling diagonally.

Special thanks

  • Dylan Bennet for the excellent tutorials on YouTube.
  • Ztiro Moritz for the "Shooter in 16 gifs" tutorial:
    • the "for e in all(enemies)" code
    • the explosion code
    • the collision code
  • Lazy Devs on YouTube for the most detailed tutorials I've seen

I'm just getting into tracking with pico-8 and this is a test for me to see how uploading carts to the site works.
The track name "Wandidi" was decided by my 5-year-old, and he also came up with the main melody.

We might add more to it, hence the post in the WIP forum.

Thanks for checking in <3
