jump force

[magic birch]

Is the inspector value 11 or 1? @fair sun

also don’t multiply by mass

if it’s 1 in the inspector, you’ll have to share more code

[fair sun]

sorry for not responding i was away

[fair sun]

the inspector value of 11 is the value that the player ends up jumping to

[magic birch]

if the inspector value is 11, then the player will jump 11 units high

[fair sun]

no the inspector value is 2

the player reaches 11

surprised dyno worked here

[magic birch]

syntax highlighting would’ve been fine, but oh well

[magic birch]

remove the mass multiplication

[fair sun]

it has no effect on the result

[magic birch]

what is ModularPlayerPhysics?

[magic birch]

also what’s the value of lowJumpReduce

[fair sun]

like .5

[magic birch]

what is the value of mass?

actually, better yet. Show the screenshot of the inspector

[fair sun]

1

[fair sun]

its pretty late sorry

[magic birch]

Is it using all the jumpCounts at once?

[fair sun]

no thats just for double jump

[magic birch]

right… what I mean asking is if it’s using up both jumps at once

[fair sun]

theyre not

i can double jump and that resulted in me jumping to 22

[magic birch]

I think I see it now. Your custom gravity is actually super weak because it’s scaling by time delta twice

[magic birch]

jumpForce = Mathf.Sqrt(-2f * jumpHeight * -physicsScript.gravityScale * Time.fixedDeltaTime)``` try that perhaps

[fair sun]

ill try tomorrow but its pretty late today

thx

[magic birch]

When you say it goes up 11 units. Is that an exact measurement or a guess?

[fair sun]

like i see the value in the transform component

[fair sun]

gets me very close to the value but never to the one i set

[magic birch]

exactly how close?

[fair sun]

well im in another thread rn and your result got me close by the decimal, but your method cant work for unity because unity's physics system is not like real life

[magic birch]

I don’t understand what you mean on why mine won’t work for unity

[fair sun]

because yours is based on real life gravity which is not how unity handles physics

because unity has a different way of making physics

[magic birch]

A normal rigidbody uses the same equation.
Your’s is slightly different since your fall gravity multiplied by time delta twice which is slightly incorrect but the newer calculation should’ve compensated for that.

[fair sun]

well it didnt

[magic birch]

how off is it. the tenth place or the hundredth place?

[fair sun]

.2 units

[magic birch]

is it consistently .2?

[fair sun]

idk, its very decimal but ive debugged the force and its always the same value

[magic birch]

lemme test something out. How long does it take for your player to reach its jump height

time the jump

[fair sun]

like .5 a second if i had to guess

[magic birch]

and this is for jump height 2?

[fair sun]

yes

[magic birch]

huh, not what I expected

[fair sun]

i mean i didnt count the jump length.
its about a normal jump

[magic birch]

This is a full jump right?

like from ground to height

[fair sun]

yeah its from ground to peak but the peak is shorter than the height i inputted

[magic birch]

what’s the gravity force. I need that as well

[fair sun]

gravityForce = gravityScale * gravityMultiplier;
gravityScale = 9.81
gravityMultiplier = 100

[magic birch]

what’s gravity multiplier? I don’t see it in the scripts you sent me

[fair sun]

https://pastebin.com/a4XaEvfP

changed it a bit

[magic birch]

is it 100 because it felt floaty before?

[fair sun]

yeah but i also make it stronger when falling

[fair sun]

well its no longer applied

[magic birch]

oh I see that now, you switched it to acceleration

lemme think for a sec

[magic birch]

based on this new snippet:

        playerScript.rb.AddForce(-transform.up * gravityForce *  appliedFallForce, ForceMode.Acceleration);```
the new calculation should be 
```cs
jumpPower = Mathf.Sqrt(-2f * -gravityForce * jumpHeight);```
This is assuming that your air drag is 0 and that fall force is 1 for the entirety of the upwards movement.

[fair sun]

air drag is not 0 and the fall force is only applied once the player is already decending

but i think the drag might be the problem

[magic birch]

drag is probably why then

[magic birch]

is there a reason you have drag?

[fair sun]

idk

[magic birch]

set it to 0 and see if it feels ok

[fair sun]

ill try tomorrow

[fair sun]

nevermind, i think i found the problem

because the player is grounded for 1 frame while performing the jump, it starts with the ground drag value
