verbal heath
Yeah, I just gotta make sure this works, so I don't mislead you
verbal heath
So, are you familiar with variables like floats?
Asking so I know how to explain this.
ashen prawn
i know them a bit
floats are decimals, variables are things that can change
i think
verbal heath
Yeah, that's right.
ashen prawn
like private bool isJumping;
verbal heath
So, when you create a c# script in Unity, the script starts off looking something like this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class JumpScript : MonoBehaviour
{
Start()
{
}
Update()
{
}
}
Yes
verbal heath
You'll need to create a float in the header. We'll name it jumpPower
ashen prawn
Alright
verbal heath
So, when you create a c# script in Unity, the script starts off looking like this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class JumpScript : MonoBehaviour
{
//THE HEADER IS IN THIS SPACE RIGHT HERE
public float jumpPower;
Start()
{
}
Update()
{
}
}
K
verbal heath
Unity has this "function" called Time.deltaTime
verbal heath
This is how we'll add the power in
ashen prawn
Alright
verbal heath
So, when you create a c# script in Unity, the script starts off looking like this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class JumpScript : MonoBehaviour
{
Start()
{
}
Update()
{
if (Input.GetKey(KeyCode.Space))
{
jumpPower += someNumber * Time.deltaTime
}
}
}
In this, we're adding the product of someNumber and Time.deltaTime to jumpPower
haha, you're right. I forgot that part. Hold on
verbal heath
Yes
Input.GetKey(KeyCode.Space)
While it's in Update(), it's checking if the user is holding down the space bar
So, IF the user is holding space down, add the product of someNumber and Time.deltaTime to jumpPower
EVERY SECOND
Following?
verbal heath
Now, someNumber can be any number you want.
You would change it to change the speed of jumpPower changing
ashen prawn
Ah
verbal heath
So, jumpPower += 2f * Time.deltaTime would make jumpPower go up at 2 per second, instead of 1 per second
ashen prawn
yes
verbal heath
jumpPower += 3f * Time.deltaTime would make it go up at 3 per second
Now that just makes the number go up. That doesn't really help us.
How are you making the jumping happen?
Are you using rigidbody.AddForce? Or have you started programming the actual jumping yet?
verbal heath
Could you send me a screenshot of that script, please?
ashen prawn
Sure
jump force is the name i used
It doesnāt like update
private void Jump()
{
if (grounded)
{
readyToJump = false;
//Add jump forces
rb.AddForce(Vector2.up * jumpForce * 1.5f);
rb.AddForce(normalVector * jumpForce * 0.5f);
//If jumping while falling, reset y velocity.
Vector3 vel = rb.velocity;
if (rb.velocity.y < 0.5f)
rb.velocity = new Vector3(vel.x, 0, vel.z);
else if (rb.velocity.y > 0)
rb.velocity = new Vector3(vel.x, vel.y / 2, vel.z);
Invoke(nameof(ResetJump), jumpCooldown);
}
if (!grounded)
{
readyToJump = false;
//Add jump forces
rb.AddForce(orientation.forward * jumpForce * 1f);
rb.AddForce(Vector2.up * jumpForce * 1.5f);
rb.AddForce(normalVector * jumpForce * 0.5f);
//Reset Velocity
rb.velocity = Vector3.zero;
//Disable dashForceCounter if doublejumping while dashing
allowDashForceCounter = false;
Invoke(nameof(ResetJump), jumpCooldown);
}```this is jump script
verbal heath
Well, Update() needs to be void Update() instead. Otherwise, the compiler won't recognize it.
ashen prawn
Ah
verbal heath
When you change that, does anything change?
ashen prawn
I have another update script in my c# file I have to move it there first
I donāt notice a difference
verbal heath
Alright. So, as of right now, nothing should happen after you let go of space, unless I missed something in this script
ashen prawn
I will make the multiplier bigger
verbal heath
So, the character is physically jumping in the scene?
ashen prawn
Itās the same if hold and if I donāt
ashen prawn
So, the character is physically jumping in the scene?
Yes
verbal heath
Then, where is Jump() being called from? I don't see anything calling Jump() from the screen shot you sent.
ashen prawn
And if I change the multiplier to 100 I definitely jump higher, but itās not different between holding and not holding
ashen prawn
Then, where is `Jump()` being called from? I don't see anything calling `Jump()`...
Lemme check
ashen prawn
```cs
private void Jump()
{
if (grounded)
{
rea...
Here
I sent my jump script
Earlier
verbal heath
No, that would be the Jump() method itself. I'm looking for where Jump() is being called.
ashen prawn
Can I click on references to see where it is called?
verbal heath
For example:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class JumpScript : MonoBehaviour
{
Start()
{
}
public void Jump()
{
//Do stuff
}
Update()
{
if (Input.GetKey(KeyCode.Space))
{
jumpPower += someNumber * Time.deltaTime
}
if (Input.GetKey(KeyCode.E))
{
Jump(); //JUMP() IS BEING CALLED HERE
}
}
}
Yeah, I think you shift + click the refernce
ashen prawn
Ok then:
if (Input.GetButtonDown("Jump") && !grounded && doubleJumpsLeft >= 1)
{
Jump();
doubleJumpsLeft--;
}```i have double jumps
the other place it is called is for my eventual addition of jetpacks
if (readyToJump && jumping && grounded && !rocketActive) Jump();```nvm
this is also for jumping if im not mistaken
because ! means "not"
verbal heath
Oh wait
Did you want the player to jump after they've let go of space, or did you want them to jump immediately and the duration of the jump is how long they're holding down space?
ashen prawn
prolly how long they are holding space because making it jump after seems kinda clunky
like in rocket league if you tap jump, it jumps immediately depending on how long you pressed
verbal heath
Yeah, I could see how that would get annoying
ashen prawn
It would definitely work for something that you ācharge upā but idk about jumping
verbal heath
Oh ok. I think I got it
Does your character controller script have its own way to do gravity?
Or are you using a rigidbody?
ashen prawn
I think so, I didnāt write I just edited it to my needs
ashen prawn
Or are you using a rigidbody?
Iām using rigid body
verbal heath
Alright. You could apply a force the whole way up instead of a single impulse
Could you paste your whole script here, if you don't mind? https://pastebin.com/
ashen prawn
So ignoring syntax, if space key pressed count time pressed and add/multiply that value to force?
ashen prawn

Well, not exactly, anymore. My bad. I should've asked you to clarify what kind of jumping you wanted. Disregard the other things I said. Because I can't think of anything else, I think applying force all the way up would be the way to go.
