Creating this blog to house my tweetcarts.
The first is this fireball creation ☄️

pset instead of CLS
pset is used to check pixel colour and change the colour to one lower in the COL table.
two circles spinning around which get small as the radius from the centre gets smaller.

Flappy Words

I had the idea of creating some educational game parodies, and this is the first.

🐤 Fly through the pipes to spell animal names!
🐤 See what words you spelt at the end of the game!
🐤 Points!
🐤 Bird!
🐤 FREE!
🐤 Use in your class!*

The main code and the pipe sprite are from @jalecko's wonderful tutorial.

*A friend of mine has already told me he will use this game in his class to start a conversation about how crappy educational games can be.

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.

2D Movement

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)

A top-down Smash TV clone

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

Wandidi - music made with my son

Fri, 31 Jan 2020 04:12:45 UTC

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
