Why ? My character is fall to floor very slow
i want too make my character fall very fast
this is my character script
var speed:float=5;
var onFloor:boolean=false;
var gravitypoint:float=1;
function Update ()
{
if(Input.GetButton("Horizontal"))
{
rigidbody.velocity = Vector3 (Input.GetAxis("Horizontal")*speed,rigidbody.velocity.y,0);
if (Input.GetAxis("Horizontal")>0)
{transform.localScale.x=-187;
side=1;
}
else
{transform.localScale.x=187;
side=0;}
}
if(Input.GetButton("Jump")&& onFloor)
{rigidbody.velocity = Vector3(rigidbody.velocity.x,-Physics.gravity.y*gravitypoint,0);}
var hit:RaycastHit;
var rayCastLenght=15;
if(Physics.Raycast(transform.position,-Vector3.up,hit,rayCastLenght))
{
if(hit.collider.gameObject.tag=="box")
{ onFloor=true;}
}
else
{ onFloor=false;
}
}
Try changing gravity settings in Edit/Project Settings/Physics, or scale down your character.
Maybe your character is very very big? In that case everything appears to fall slower. If your character is 2 units tall, it would appear to fall faster. Obviously they would fall at the same accelerating rate, but bigger objects don’t fall faster than smaller object or vice versa. They still travel the same distance. But for a big object to fall 0.5 meters in a second makes it look like it’s not falling very fast at all. However a needle falling 0.5 meters makes it look like it’s falling quite fast. I see your localscale is 187, this suggests that you have a character that is 200 meters wide. Perhaps something like 600 meters tall? It wouldn’t appear to fall very fast.
i had the same problem. i didn’t want to mess with the physics (like changing gravity, etc.). i noticed the issue was related to the animator controller. if your character behaves as expected when you remove the controller from the animator component, then try baking the root transform position (y), and reactivate your controller. this should solve your problem.
If you are using an animator controller, you can disable “Apply root motion” under your caracter’s Animator.
check if there arent any colliders apart from the actuall player
