I've started up a new project and I'll be making extensive use of the trig-functions, so I started playing around with them. I soon found out about the input range and the inverted sin, but I still can not explain the behavior I'm seeing.
What you would expect from sin(x)cos(x) and what you can intuitively read from the graph is that first peak of sin(x)cos(x) should be negative, and the second positive. The actual behavior can be explained by the inverted sin-function, but with the inverted sin-function, I would expect the sin-graph to reflect the inversion, which it does not.
Code:
function _draw()
cls()
print("cos(x)",10)
print("sin(x)",12)
print("sin(x)*cos(x)",14)
for x=1, 127 do
pset(x, 64,3)
pset(x, 64+32*cos(x/127),10)
pset(x, 64+32*sin(x/127),12)
pset(x, 64+32*sin(x/127)*cos(x/127),14)
end
end |
(Sorry, I don't know how to format code on the BBS)

So I've had this idea for a platformer fighting game and I'm having trouble coming up with the key binds
Obviously jump is z and attack is x and we have the four directional imputs, but then I want to add a dodge/parry, a strong attack and a special so does anyone have any ideas
i made a new profile picture for my Game Jolt and itch profiles, so for Lexaloffle i made it again but in PICO-8:
gradient effect is from this post:

Based in this coding chalenge: https://www.youtube.com/watch?v=Ggxt06qSAe4

Use arrow keys to change the seed.
Hello user of lexaloffle!
My name is charisios and i welcome you to my profile wich you can find awsome games made with the support of the lexaloffle game engines! Have a nice day.
Goodbye,

This is my first blog update. I'm feeling a bit defeated. I'm not making meaningful progress any more. The progress I have made is all but entirely owed to tutorials from nerdy teachers and lazy devs. I'm now spending way more of my time trying to find relevant content to learn from than I am actually learning. I've spent hours combing through BBS posts, reddit, youtube, and discord. When I do find discussion that seems relevant to what I want do, it's rare that I am able to parse the code to learn from it. Trying to stay motivated and move forward.
What I have thus far:
-A running, jumping player sprite which I don't understand how to further animate without continuously looping through a cycle of sprites (How do I do a once-and-done animation?)
-A functional camera that follows the player
-Collision detection for the map tiles
-An expanding and contracting field of view effect which I have no idea how to adjust due to the math involved.
-A particle effect simulating kicked-up dirt whose location I'm not fully able to anchor behind the sprite when it's flipped.
What I would like to have:
-Some sort of animated background, perhaps glistening or dripping rocks.
-Breakable tiles for a digging mechanic.
Hello! I was working on a 2D platformer, and I was wondering about how to make enemies. The cartridge that is attached above (I hope it is attached) shows a small demo of the game thus far.
(NOTE: this is based off the Nerdy Teachers 2D platformer tutorial)
As you can see, there is collision, semisolid platforms and even some spikes that can kill the player however, I am focused on the "frog" on the middle left platform. So far I have gotten it to walk forward and change directions when hitting sprite 2 (left turns) and sprite flag 3 (right turns). But I cannot for the life of me get the frog sprite to flip when turning. More importantly I cannot get the frog to kill the player like the spikes do. If you have any ideas or advice about the enemies or just in general please crack open my code and take a look.
(NOTE: this is built off an older project of mine that I never finished, that is why there is code for "Glide" and "Slamming" and "Glidingdash" that seemingly does nothing and also why the thumbnail reads "Flemingo Quest")
P.S I am looking for a name for the little bird guy you play as, any ideas?
EDIT: Forgot to mention that the number follows the player it your current speed, used for debugging n' such
EDIT 2: After implementing the tuning code I am struggling with the frog killing the player so far I got this but
the death part does not seem to function properly.
function frog_update()
if collide_map(frog,"up",2) then
frog.turning=true
elseif collide_map(frog,"up",3) then
frog.turning=false
elseif frog.x == player.x and frog.y == player.y then
_draw=death_draw
_update=death_update
_init=death_init
end
end

Jebediah Peppermint - The Gun Wizard
~WORK IN PROGRESS~
Hi I'm Wash, 👋
I'm making small games based on every player character in the actual play D&D podcast, The Winged Badger Tavern that I play in.
In this game you play as my first character, Jebediah Peppermint, the molefolk gun-wizard who spits fire and fires spit. You'll fly through the sky atop your trusty blunderbuss 'Big Boy' and shoot down the evil forces of The Brightworld Company.
Watch live Monday's at 8:00pm EST
The gameplay is based on Lazy Dev's Academy shmup tutorial
Shoot baddies to fill your ammo. Use your ammo to fire BIG BULLETS and get a high score!
O - Shoot Bullets
X - Change Weapon
Big Bullets take shells. Regain shells by killing blue enemies.
Shooting Temp Baddies
New Weapon: Lightning Bolt!

Explaination
This is just a demo, and I'm sort of tired of sprite-stacking. These past few months have been kind of rough on me, and I honestly can't make this into the game I was planning...
Thx for clicking/playing! Love you guys!

Some fun game :)
What is this?
This is a short cute lil' game about a tiny cat visiting its dream(z). This game has three quick mini-games to play, from math problems, to a chase sequence. This was made for the GW Game Jam #2, and was made in Pico - 8 under 7 days. The music was made by Gruber Music and the dialogue system used was DTB made by Oli414.
How do I play?
The game is incredibly simple. The controls are:
Left / Right / Up / Down Arrow Keys -> Move
X / V / N -> Do action
Z / C / M -> Hold while moving to move faster. Press to advance through text.

Quiet Helix
You are agent Casey Quiet of the Office of Unbordered Nations (OUN). The OUN has sent you to an unregistered base in the Arctic circle which has been rumored to be performing genetic tests on human subjects. These subjects have been taken against their will by Leader Bank, a former scientist in the United States Navy.
Your mission consists of 3 main tasks.
1: Recover all genetic vial samples of Bank's tests.
2: Rescue or dispose of any living test subjects.
3: Eliminate Leader Bank by any means necessary.
Be careful while exploring the base. Intel suggests Bank has installed electric fences and security cameras to defend against exactly what you are doing, and our infrared scanners have also detected a number of landmines in the vicinity.
You can climb over the fences (and it is likely that you will need to at some point) but you will take damage. Keep your eye peeled for ways to refill your health during the mission.
For the cameras, just try to stay out of line of sight as much as possible. If your alarm meter reaches 100 an alert will be raised and the mission will fail.
Good luck, Agent Quiet. Approaching Helix Base...
I have a handheld device (RG351V) that runs Pico 8 and Splore. I like to browse Splore at home while connected to Wi-Fi and Favorite games that I like. When I do that, some games are playable even offline, but some are not and give the error "could not connect to BBS."
I am not doing any special steps like downloading the cart manually. Some just seem to randomly work offline without me doing anything. Can anyone help me figure out what's going on? I'd like to play them all offline as easily as possible.
