Trying to figure out ball on rope equation.

[night sleet]

Basically I’m trying to program it to where depending on player joystick input player will rotate around the axis instead of their velocity just going in that direction

[night sleet]

Idk if I tagged this correctly

Basically trying to make ODM gear from Attack On Titan so it’s kinda like a grapple hook that can reel in and fly in a way lol

I just need an equation for kind of a tether ball type problem

I’m not really sure how else to explain it

[fossil zephyr]

purple is the torque

so this would have very little velocity correct?

[night sleet]

Idk

I don’t know this stuff that’s why I’m struggling to explain it

[fossil zephyr]

purple is controller input

so like

this would have more velocity than the other image right?

is that what you mean?

[night sleet]

So straight into the radius would Just put slack in the line so slower

[fossil zephyr]

ok yeah

lot of vector math

[night sleet]

This is the direction I would want it to be

[fossil zephyr]

yes, correct

[night sleet]

😭

[fossil zephyr]

but if the joystick was parallel to radius there would be no velocity right?

[night sleet]

I’m decent with vector math. I do a lot of it so I don’t know if there’s something more to it or not though.

[night sleet]

Yes I would just send the player forward

[fossil zephyr]

so if blue is ur tangent line

[night sleet]

Or make them drop in a grapple hook fashion

[fossil zephyr]

you need to split ur controller input vector into two components, one parallel to ur tangent line and one perpendicular

[night sleet]

I am so sorry what is a tangent line?

[fossil zephyr]

ur parallel vector is ur movement along the circle, ur perpendicular is ur forward force

[fossil zephyr]

tangent line is a line that only touches the circle at one point

[night sleet]

Ok

[night sleet]

Yes I wanna make it to where the player can hold left and make a rotation

[fossil zephyr]

yeah i think i understand what u mean now

but this would be hard because you'd have to sample ur controller input and ur ball's position on the circle at small intervals of time and recalculate ur vectors

[night sleet]

Player is the ball

[fossil zephyr]

yeah ik

[night sleet]

Ok

[silent arrow]

Wait sorry if i may interject

[fossil zephyr]

i could get you an equation but it would take me quite a long time to program something like this

[silent arrow]

If the player holds the joystick forwards does he just go in circles

[night sleet]

It would be parallel with the radius so they would just go forward because the slack in the line would loosen

They wouldn’t really go in a circle because the centripetal force isn’t really there cause of slack
Right?

[night sleet]

Oh, I don’t wanna bother you like that. I’ll just do some more research.

[fossil zephyr]

i mean id love to do it (its very fun) but you wouldn't be able to program it if you didn't fully understand how it works

[silent arrow]

What game engine u using anyway

[fossil zephyr]

id give u the equation and u'd just be confused as hell

[night sleet]

I’m a quick learner in a way

[night sleet]

Still better than nothing

[fossil zephyr]

yeah but u need to understand how it works in order to program it, thats why id rather u make the equation urself so you understand how it works lol

[night sleet]

Corny af but I don’t have a computer but I have a vr so I program in a sandbox game called recroom

[silent arrow]

Tbh w

Do you code in vr😭

[night sleet]

Yeah, I just still barely know where to start

[night sleet]

Yes

[silent arrow]

Is it like block coding

[night sleet]

It’s a block type code

[night sleet]

Yee

[silent arrow]

Ah ok

Tried rec room on mobile once but it's kinda shit on mobile

[fossil zephyr]

oh block coding?

uh

[night sleet]

Oh yeah it was a vr game to begin

[fossil zephyr]

good luck programming this in block coding 💀

[night sleet]

It’s like all the functions you would see in normal coding, but you just don’t have to type it

[silent arrow]

People have programmed Linux emulators on scratch so

[fossil zephyr]

i hope so

[night sleet]

It’s not like there’s less customization

[fossil zephyr]

idk i dont do block coding lmao

[silent arrow]

It just gets a bit cluttered sometimes tbh

[night sleet]

Something I made recently using the block coding

[silent arrow]

I'm already giddy jesus

I would have motion sickness programming in this

[night sleet]

And I taught myself enough math to figure out this

[fossil zephyr]

btw we should move back to discussion

[night sleet]

Although the majority of that is a algebraic 0<->1 ping pong

[night sleet]

Oh yeah

[fossil zephyr]

ill be going tho, gotta do physics homework

[night sleet]

Just showing that it can be done with block code

[night sleet]

Have fun

[fossil zephyr]

not happening

[night sleet]

Fr

[silent arrow]

Btw is the string always taut

[night sleet]

?

[silent arrow]

Does the string ever bend

[night sleet]

Oh for the wires yeah I think rr uses a cubic bezier

Or something a little more than that

[silent arrow]

Have you attempted anything yet?

Like in code

[night sleet]

No

Brain hurty

[silent arrow]

Fr

I just finished 3 exams😭

[night sleet]

I’m about to try it though

[night sleet]

I’ve been in work mode all day. I’ve completed 13 assignments for college and I’ve been trying to manage and organize a game studio at the same time.

Today I created the design for two rooms created ideas for two rooms created concept art for mascots somehow gotten contact with two famous people on rr to help us promote our group and I’m still up trying to figure out super complex math stuff for the game development group

The grind is painful

I’m gonna go to bed

[silent arrow]

The grind is real
