RigidbodyFPSWalker climbing walls
Hey,
I am using a rigidbody fps controller with this script : http://wiki.unity3d.com/index.php?title=RigidbodyFPSWalker and it seems to be able to climb up walls if you hold the w key, face the wall front on and spam the space bar. Does anybody know how I could fix this? Or is there a better rigidbody fps Controller that i could use? I need it to be rigidbody because it needs to interact with other rigidbodies and i need to apply Physics.gravity to it.
Thnx in advance.
ok there are two simple solutions, you could change you rigidbody movement for character controller movement (see character controller in script reference), and you can keep the rigidbody
Or you could set cubes near the walls, just turn off the renderer, for invisible cubes, is no the best option but that could help.
feel free to send me private message if you need more help.
Hey, the character controller thing worked well but it stops the ability to push around cubes. Do you know how i could fix that?
did you kept the rigid body?, also you can fake this, by tigger, you can deactive the rigidbody gravity, and activate it again when you hit the trigger, you set the trigger near a box for example, and then you can move the box
I kept the rigidbody, also it doesn't use rigidbody gravity. I need this functionality so that the character can walk on walls and the roof
I kept the rigidbody on the character but it doesn't use the physics.gravity when it has Character Controller on it aswell
As a solution I have made a little change in RigidbodyFPSWalker. Actually copied some code in it from CharacterMotor.
#pragma strict
var speed = 10.0;
var gravity = 10.0;
var maxVelocityChange = 10.0;

private var grounded = false;
private var groundNormal: Vector3;

private var tooSteep: boolean = false;
@script RequireComponent(Rigidbody, CapsuleCollider, CharacterController)
function Awake () {
rigidbody.freezeRotation = true;
//rigidbody.useGravity = false;
controller = GetComponent (CharacterController);
}
function FixedUpdate () {
if (grounded) {
if(!tooSteep) {
// Calculate how fast we should be moving
var targetVelocity = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
targetVelocity = transform.TransformDirection(targetVelocity);
targetVelocity *= speed;
// Apply a force that attempts to reach our target velocity
var velocity = rigidbody.velocity;
var velocityChange = (targetVelocity - velocity);
velocityChange.x = Mathf.Clamp(velocityChange.x, -maxVelocityChange, maxVelocityChange);
velocityChange.z = Mathf.Clamp(velocityChange.z, -maxVelocityChange, maxVelocityChange);
velocityChange.y = 0;
rigidbody.AddForce(velocityChange, ForceMode.VelocityChange);
}
// Jump
if (canJump && Input.GetButton("Jump")) {
rigidbody.velocity = Vector3(velocity.x, 0, velocity.z) + Vector3.Lerp(Vector3(0, 1, 0), groundNormal, jumpPerpAmount) * CalculateJumpVerticalSpeed();
}
}
// We apply gravity manually for more tuning control
rigidbody.AddForce(Vector3 (0, -gravity * rigidbody.mass, 0));
grounded = false;
groundNormal = Vector3(0, 0, 0);
tooSteep = true;
}
function OnCollisionStay (collision : Collision) {
for(var contact: ContactPoint in collision.contacts) {
groundNormal += contact.normal;
if(contact.normal.y > Mathf.Cos(controller.slopeLimit * Mathf.Deg2Rad)) {
tooSteep = false;
}
}
if(collision.contacts.Length > 0) {
groundNormal /= collision.contacts.Length;
}
grounded = true;
}
function CalculateJumpVerticalSpeed () {
// From the jump height and gravity we deduce the upwards speed
// for the character to reach at the apex.
return Mathf.Sqrt(2 * jumpHeight * gravity);
}
