Hello,

I am working on a Character Controller, for this i followed a video... just like in the video I also included double Jump (https://www.youtube.com/watch?v=QGDeafTx5ug&ab_channel=Blackthornprod)

But now i wanted to also implement Coyote Time and Jump Buffering... so how can i do this ?

I followed some Tutorials for them but they all do not with the double jump mechanic...

I dont know much about programming so I really need help..

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class CharacterController : MonoBehaviour

{

public float speed;

public float jumpForce;

private float moveInput;

private bool facingRight = true;

private Rigidbody2D rb;

private bool isGrounded;

public Transform groundCheck;

public float checkRadius;

public LayerMask whatIsGround;

private int extraJumps;

public int extraJumpsValue;

void Start()

{

extraJumps = extraJumpsValue;

rb = GetComponent<Rigidbody2D>();

}

void FixedUpdate()

{

isGrounded = Physics2D.OverlapCircle(groundCheck.position, checkRadius, whatIsGround);

moveInput = Input.GetAxis("Horizontal");

rb.velocity = new Vector2(moveInput * speed, rb.velocity.y);

if(facingRight == false && moveInput > 0)

{

Flip();

}

else if(facingRight == true && moveInput < 0)

{

Flip();

}

}

void Update()

{

if(isGrounded == true)

{

extraJumps = extraJumpsValue;

}

if(Input.GetKeyDown(KeyCode.W) && extraJumps > 0)

{

rb.velocity = Vector2.up * jumpForce;

extraJumps--;

}

else if(Input.GetKeyDown(KeyCode.W) && extraJumps == 0 && isGrounded == true)

{

rb.velocity = Vector2.up * jumpForce;

}

}

void Flip()

{

facingRight = !facingRight;

Vector3 Scaler = transform.localScale;

Scaler.x *= -1;

transform.localScale = Scaler;

}

}

I really hope you Guys can Help me... thanks for every Answer :)

How about something like this:

int jumps = 0; // Track jumps made so far
int jumpsAvailable = 2; // Double jump
float coyoteTime = 0.1f; // It's in the name
float coyoteStart; // When we last touched ground

// You should probably compartmentalize this
void Update()
{
	//Do your ground check logic here. I would think Raycast is better than a circle, because a circle will return if ground is to either side of you or if you're moving up through a platform. Either way, now we have a bool isGrounded.
	if (isGrounded)
	{
		coyoteStart = Time.time;
	}
	else
	{
		if (Time.time > (coyoteStart + coyoteTime)
		{
			if (jumps = 0) jumps = 1; //If player hasn't jumped yet, discard their first jump
		}
	}
	
	if (jump input)
	{
		if (jumps < jumpsAvailable)
		{
			// Jump logic
			jumps += 1;
		}
	}
}

It's sloppy, but hopefully you get the idea.

Basically, have a reservoir of jumps. If the player jumps, deduct one. When coyote time runs out, if the player hasn't jumped yet, deduct the first jump.

Sorry, I completely glossed over the jump buffering bit. For that you could use something like

float jumpBuffer = 0.1f;
float lastInput;
bool jump = False;

void Update()
{
	if (Input.keyDown) 
	{
		lastInput = Time.time;
	}
	if (isGrounded)
	{
		if (Time.time <= (lastInput + jumpBuffer))
		{
			jump = true;
		}
	}
}

Then, in the previous script, jump input would just be your bool jump

I haven't tried any of this; I haven't even made a platformer yet. But I think the idea should work.

@phlp thank you… im going to try this later…

but really thanks for the answer ?

@Peee3 No problem. Let me know how it works out.
