Limit mouse position so that player launches same distance
Player dashes towards the mouse position, however, lets say you put the cursor far-right like x(20) so player moves 20mt but if you put it x(5) player dashes 5mt how can I limit the pos. input so the player would travel the same distance no matter the mouse position distance.
I want to get the mouse direction and launch the player same distance no matter the mouse position distance.
//this is inside the Fixed Update method.
float xor = Input.GetAxis("Horizontal"), yor = Input.GetAxis("Vertical");
if ((xor != 0 || yor != 0) && !dash)
{
rg2d.velocity = new Vector2(xor * speed, yor * speed);
anim.SetFloat("speed", Mathf.Abs(xor + yor));
}
if(Input.GetKeyDown(KeyCode.Mouse0) && !fire)
{
//PUNCH
dash = true;
fire = true;
StartCoroutine(Stop_Fire(0.5f));
anim.SetTrigger("attack");
fist.GetComponent<Collider2D>().enabled = true;
Vector2 pos = (transform.position - Camera.main.ScreenToWorldPoint(Input.mousePosition)).normalized;
rg2d.AddForce(-pos * punch_force, ForceMode2D.Impulse);
}
//I call this function at the end of the attack animation.in the Animation window
public void Stop_Dash()
{
dash = false;
fire = false;
fist.GetComponent<Collider2D>().enabled = false;
rg2d.velocity = Vector2.zero;
}
The problem was the mouse input z-axis. it was unused but still had a big value that effected the normalization.
instead of :
Vector2 pos = (transform.position Camera.main.ScreenToWorldPoint(Input.mousePosition)).normalized;
this should be used:
Vector3 mousepos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector3 moveDirection = (transform.position - mousepos);
moveDirection.z = 0;
moveDirection.Normalize();
rg2d.AddForce(-moveDirection * punch_force, ForceMode2D.Impulse);
well clamping is not the right solution that is correct. Try the following line instead:
Vector2 pos = transform. position + (transform.position - Camera.main.ScreenToWorldPoint(Input.mousePosition)).normalized * yourMaximumDashDistance;
you will probably have to adjust some values ot get the right distance but this should result in a "clamped relative position" to your character.
Share the result :)
i tried changing the value but sadly this does not work, is there a way to only get the direction of the mouse and add force towards that direction regardless of its distance.
Oh well i just realised you have some other big issue in your current code:
GetAxis will never be true for just one Update....
So depending on how long you click the result will be different... You should rather choose something like GetButtonDown to have a single even or follow this answer here...
let me know if that solved your issue.
i edited the code to show what i changed but still player launches depending on the mouse distance
