My remix of 2d platformer physics 0.6.15

person

So i stole this a while back and started to improve it. i added grappling hook, but its super buggy, you no clip thru walls, and the movement is basically compromised after using it. any tips on how to make this thing work?

also who made this, i want to give credit, but i dont know who to give credit to.

Varrience

thestarchypotat did, i helped him debug most of his engine for when he first published it a shame that people took his comment block out, i think i may still have a link to his discord... but it's not really focused on programming also you may want to reset the rotation value to 0 after using the grappling hook so those physics don't manifest after using it

INTERNECION its not mine but thank you?
Varrience so when i try to set the rotation to 0 it makes jumping impossible and i'm still sideways

This is actually incredibly well made. I like the movement effect on our main box here

person

also the noclipping basically makes the game really easy

INTERNECION

person until you noclip into the backrooms

person

maybe ill do that then. level 14 the backrooms level

person

there its done. the backrooms

person

still need help :p

if ((ground.isTouching(mouse) && grapple_unlocked == true) && (keyDown("g") || mouseDown("leftButton"))) {
  dir4 = player.getDirection();
  player.setSpeedAndDirection(7, 0);
  player.pointTo(camera.mouseX, camera.mouseY);
  player.rotateToDirection = true;
  line(player.x, player.y, camera.mouseX, camera.mouseY);
} else if ((keyWentUp("g") || mouseWentUp("leftButton"))) {
  player.rotation = -90;
  player.rotateToDirection = false;
  //player.rotation = 90;
}```

well i fixed it... i mean if you knew how to debug and read documentation it's fairly simple
CDO even has naïve documentation for this as well which is also common practice for debugging, rotateToDirection is a Boolean if JS was more strict it would be easier to find so this should probably fix one of your issues
Documentation Reference: https://studio.code.org/docs/ide/gamelab/expressions/rotateToDirection

sometimes i feel like i walked right into the solution and didnt even notice
thanks

i just copied and pasted that in and it still crouches sideways.
nevermind.
but i can still noclip.

Varrience

well i didn't say it was a cure-all... if you read my message i fixed the rotation problem you were having... that was a logical error
physics errors take much longer to fix for the sole reason that it's a literal pain in the ass... and for now that's something i'm not in the mood to do atm... i may get around to take a crack at it but you should try fixing it as well, it'd probably be faster than when i come around to doing it

for reference the OP of this project was having problems with his moveable box code and i did fix it eventually but the first patch took about 2hrs of experimental collisions and even custom collisions for some precaution and i was involved with a bunch of the source code and debugging of a lot of features

the glue don't work

person

i know
i kinda learned that its hard to create new groups becuase i have to create, delete, etc them
i just dont know why my velocity isnt working
