Need help fixing my double jump script.
I am trying to create a doublejump to the character controller. It works just fine, but if I walk off a platform, that counts as 1 of my 2 jumps. How can I fix this?
void FixedUpdate()
{
// The player is grounded if a circlecast to the groundcheck position hits anything designated as ground
grounded = Physics2D.OverlapCircle(groundCheck.position, groundedRadius, whatIsGround);
anim.SetBool("Ground", grounded);
// Set the vertical animation
anim.SetFloat("vSpeed", rigidbody2D.velocity.y);
//Reset DoubleJump
if (grounded)
{
doubleJump = false;
}
}
public void Move(float move, bool crouch, bool jump)
{
// If crouching, check to see if the character can stand up
if(!crouch && anim.GetBool("Crouch"))
{
// If the character has a ceiling preventing them from standing up, keep them crouching
if( Physics2D.OverlapCircle(ceilingCheck.position, ceilingRadius, whatIsGround))
crouch = true;
}
// Set whether or not the character is crouching in the animator
anim.SetBool("Crouch", crouch);
//only control the player if grounded or airControl is turned on
if(grounded || airControl)
{
// Reduce the speed if crouching by the crouchSpeed multiplier
move = (crouch ? move * crouchSpeed : move);
// The Speed animator parameter is set to the absolute value of the horizontal input.
anim.SetFloat("Speed", Mathf.Abs(move));
// Move the character
rigidbody2D.velocity = new Vector2(move * maxSpeed, rigidbody2D.velocity.y);
// If the input is moving the player right and the player is facing left...
if(move > 0 && !facingRight)
// ... flip the player.
Flip();
// Otherwise if the input is moving the player left and the player is facing right...
else if(move < 0 && facingRight)
// ... flip the player.
Flip();
}
// If the player should jump...
if ((grounded || !doubleJump) && jump) {
// Add a vertical force to the player.
anim.SetBool("Ground", false);
//zero out our current velocity
rigidbody2D.velocity = new Vector2(rigidbody2D.velocity.x, 0);
rigidbody2D.AddForce(new Vector2(0f, jumpForce));
if(!grounded && doubleJump == false)
{
doubleJump = true;
}
}
}
It's because when you walk off a platform, you aren't grounded anymore. What you can do is implement a jump counter. and allow the player to jump as long as the counter didn't reach 2. (which means ignoring the grounded boolean).
int jumpCount = 0;
if (jumpCount < 2 && jump)
{
//Jump
jumpCount++;
}
Also, don't forget to reset the jump count in the fixed Update when the player hits the ground.
void FixedUpdate()
{
//your code...
if (grounded)
{
jumpCount = 0;
}
}
Well I tried that and it was giving me 3 jumps if i was grounded, and 2 if i walked off the platform. So pretty much the same issue for some reason. I tried editing it but its still not working. This is what I ended up with
if (grounded && jumpCount < 1 && jump)
{
jumpCount++;
anim.SetBool("Ground", false);
rigidbody2D.velocity = new Vector2(rigidbody2D.velocity.x, 0);
rigidbody2D.AddForce(new Vector2(0f, jumpForce));
}
else if (jumpCount < 2 && jump)
{
jumpCount++;
anim.SetBool("Ground", false);
rigidbody2D.velocity = new Vector2(rigidbody2D.velocity.x, 0);
rigidbody2D.AddForce(new Vector2(0f, jumpForce));
}
I think i figured it out. I believe you put my code within the same function, which isn't really what i meant.
The grounded part needs to be in the fixed update, nowhere else. I'll edit my answer to better reflect that.
Sorry for the ambiguity, and tell me if that works
