Obtaining Constant Speed with AddForce
Hi, I've recently managed to get my character moving with AddForce However when the character starts moving the speed is slow and when I stop moving the character slides (obviously as it accelerates and decelerates)
I would like to make my starting velocity a multiple of direction.magnitude and the ending velocity zero.
Is this possible?
Thanks
Code :
//On Screen Controls
direction = new Vector3(joyScript.position.x, 0, joyScript.position.y);
if (direction.magnitude > 0.1f)
{
Vector3 rightMovement = right * ps3speed * Time.deltaTime * joyScript.position.x;
Vector3 upMovement = forward * ps3speed * Time.deltaTime * joyScript.position.y;
Vector3 heading = Vector3.Normalize(rightMovement + upMovement);
transform.forward = heading;
//transform.position += rightMovement;
//transform.position += upMovement;
rigidbody.AddForce(rightMovement * direction.magnitude * speed);
rigidbody.AddForce(upMovement * direction.magnitude * speed);
rigidbody.AddForce(transform.forward * direction.magnitude * speed);
playerModel.animation.Play("runforward");
playerModel.animation["runforward"].speed = direction.magnitude;
}
else
{
playerModel.animation.CrossFade("idle");
}
I'd eventually like to add the force on the player to the force of the bullet its producing so the player doesn't run into the bullet when it's fired.
You can set rigidbody.velocity to anything you want. Your AddForce() calls are a bit puzzling to me. I think you will want:
Vector3 v3 = rightMovement + upMovement + transform.forward;
v3 *= direction.magnitude * speed;
rigidbody.velocity = v3;
Note if your code above is exectued every frame in update, then you'll need to make a substantial increase in 'speed'.
As an alternative, you can substantially increase the Rigidbody.drag and adjust the 'speed' to compensate. Depending on settings, you may have just a bit of acceleration/deceleration.
$$anonymous$$Y code was a shambles I have to be honest, I'm working on implementing your suggestion as I type this I can't see why it wouldn't work so I'll make this the answer it does :)
Thanks
I set the drag to allow for a constant horizontal velocity, is there a way to not let the drag effect my vertical velocity?
