This is a simple example on how circle collision works.
All you need from this cartridge is the function:
function circ_col(c1, c2) local dx = c1.pos.x - c2.pos.x local dy = c1.pos.y - c2.pos.y local distance = sqrt(dx*dx + dy*dy) return distance <= (c1.r + c2.r) end |
If you want to check if two circles are colliding, you simply pass them as parameters c1 and c2 see an example bellow:
c1 = {
pos={x=64,y=64},
r = 4 --size the radius would have to be for a 8x8 sprite
}
c2 = {
pos={x=70,y=70},
r = 8 --size the radius would have to be for a 8x8 sprite
}
collides = false
function _update()
collides = circ_col(c1, c2)
end
function _draw()
cls()
if collides then
print("colliding",4,4,11)
end
--draw the circles here - mind you in most projects you woudn't, usually you would have them invisible and have them
--at the same position (or slightly offsetted) as your player
--i would recommend drawing them anyway at the start to see that the are always where they are supposed to be
circ(c1.pos.x,c2.pos.y,c1.r,11)
circ(c2.pos.x,c2.pos.y,c2.r,8)
end
function circ_col(c1, c2)
local dx = c1.pos.x - c2.pos.x
local dy = c1.pos.y - c2.pos.y
local distance = sqrt(dx*dx + dy*dy)
return distance <= (c1.r + c2.r)
end |

I'd love some feedback on how easy or difficult you think it is. Balancing the attack powers and enemies has been quite the challenge. <3

A small little game made for fun. Originally a collaboration project with a beginner coder friend who quickly lost interest. Feel free to add critique although please understand this wasn't intended to be particularly good.
controls:
Press O (z) to jump
Press X (x) to eat
Instructions:
A timer is ticking down. Quickly choose whether you will jump over the incoming obstacles or attempt to eat them. Eating a spike will give you a "GAME OVER", but eating a fruit will increase your speed and grant you additional time to extend your streak. Go for the highest score you can before time runs out! (my record is 8100 if you want to try and beat it)

I tried making somewhat of platformer engine.
As you can see, it is very buggy. If someone could help with the weird wall collision thing then that would be great.

When I click Code below any cart on the BBS, the block is just empty and contains no code. Not sure if this is related to the recent styling change. I can't say for sure when this started, but I just noticed it today for the first time.
In case it's browser specific, I'm on Firefox 124.0.1 on Linux.

Obviously I can only speak for myself, but I have to say I don't like the site's font having been changed to be universally monospaced. I really hope this was just a CSS accident. 😕
@zep - Was this intentional?

1k Defender
1k Defender is a little shmup made with 957 compressed bytes inside PICO-8!
This project was born from a failed submission to 1k jam 2022 and continuing it for the 2023 edition. Since I didn't felt it was eligible for the jam, I never uploaded it to it. A while ago I remembered it, so I spiced it up with a label and some sfx, but only those so it is a tad more enjoyable to play. We got a gameplay loop as well!
You can also check it out the raw one on GistHub:
https://gist.github.com/Achie72/076859ce7fe17335fdb49ca7790d427b
Gameplay:
Shoot the invading forces down to protect your planet. You need to restock on bullets from time to time in the depot (the up icon on the bottom left)

When I tried to use the flag for exporting when calling pico8 from the command line :
pico8 usas.p8 -export usas.p8.html
I get ths error message
"please capture a label first"
Is it possible to export an image from the command line, it works if I press f7 in pico8, make a capture and manually export. But I would like to script this and export the html headless.
Second question, is it possible to use another HTML template or alter the default one, so I could add initial javascript ?

Please help me write the correct code.
I would like something like that
if dir d_up then y=player.y+8,
if dir d_down then y=player.y+1,
if dir d_none or d_left or d_right then y=player.y+5

The rules are simple.
From the three cards offered you get to pick one.
The computer then picks its choice of card from the same selection.
Hunter wins against Bear
Bear wins against Ninja
Ninja wins against Hunter
Will the card you pick win?
