I have try using animator to animate the jumping animation from one place to another but it seems like it just keep repeating instead of jumping from the place that landed before.

How to make animation and change position at the same time ? ( Example , like MapleStory /Terraria Slime hoping from one place to another )

{
if (controller.isGrounded)
{
verticalVelocity = -gravity * Time.deltaTime;
if (Input.GetMouseButtonDown (0))
{
source.PlayOneShot (jump, soundVolume);
verticalVelocity = jumpForce;
}
}
else
{
verticalVelocity -= gravity * Time.deltaTime;

movement = 1;
else
movement = 0;
Vector2 moveVector = new Vector2(0,verticalVelocity);

Score tracker adding too many points per jump
In my game a player receives points every time they make a jump and there should only be one point added per jump. I have the jump() method in the Update() method and this is what the jump method calls.
public void jump()
{
if (checkCanJump())
{
myBody.velocity = new Vector2(myBody.velocity.x, jumpSpeed);
scoreTracker.scoreCount++;
}
}
checkCanJump() simply ensures that the player is touching the ground and checks to see if the player is touching the screen. When I run the game on the computer the scoring works fine but when I use my iPhone every time I jump receive 2-3 points. Why is this? Thanks!

General Jumping Mechanic Animation Question
I want to have a character jump animation without root motion.
I have a stationary jump animation and a standard character controller jump script.
The jump script instantly adds vertical velocity when I push the jump button.
But the jump animation has an anticipation key frame where they bend their knees to push off.
What is the standard method for incorporating this instant of non-vertical velocity into the jump sequence after the jump button is pushed but before the player moves up?
Thanks!

jumping from ledge problem
My movement script allows the player to jump 0.1s after going off a ledge so that it seems more realistical. Otherwise he would just slide off the ledge as soon as he reaches it. I have a Capsule with CharacterController.
The problem is that the player wont jump sometimes when on ground. It happens just once in 20 times but it happens and it would be irritating if it'd happen at a crucial moment. I tried the code without the ledge tolerance and it works perfectly fine but does someone have an idea how to solve the problem or does someone have an alternative?
the tolerance part would be the lines with jumpAllowTime, jumpAllowTimeTrack, waitToLand and waitToLandTrack
void Start()
{
player = GetComponent ();
transform.position = spawnPoint.transform.position;
jumpSpeed = Mathf.Sqrt (2 * gravity * jumpHeight);

moveSpeed = 1.0f;
moveSpeedAir = 0.6f;
//input
onGroundInput = new Vector3 (moveHorizontal,0,moveDepth);
//normalizes the vector so that diagonal movement doesn't get too fast
if (onGroundInput.magnitude > 1) {
onGroundInput.Normalize();
}
targetGroundMovement = onGroundInput;
//lets the character walk into the direction the camera is facing
targetGroundMovement = playerCamera.transform.TransformDirection (targetGroundMovement);
targetGroundMovement.y = 0;
targetGroundMovement *= onGroundInput.magnitude;

Navmesh interfering with mecanim jump animation (root motion)
Hi,
My enemy character jumping animation (applied root motion) works on its own. But as soon as I apply Nav Mesh Agent, the character does the animation in the forward direction but not in the upward direction. It seems as if the agent does not allow any motion in the Y-axis.
I've tried several animations and followed unity navmesh + mecanim manual. Any suggestions on how to solve this?

Create jumping motion with only transform.Translate
I have an empty 3D GameObject that is serving as the player in a game that I am building. I am trying to write a script that enables the player to "jump" when `SPACE` is pressed. I want to do this using kinematic equations, and with only `transform.Translate`. Here is the code I have so far:
public float fallingSpeed;
void Update () {
if (Input.GetKey (KeyCode.Space)) {
Jump ();
}
}
public void Jump () {
float yPosition = 0.5f;
// Don't let player fall through floor
if (transform.position.y <= 0.5f) {
fallingSpeed = 0.0f;
} else {
fallingSpeed -= 9.8f * Time.deltaTime;
yPosition += fallingSpeed * Time.deltaTime;
}
// Translate y-position
transform.Translate (new Vector3 (0.0f, yPosition, 0.0f));
}
Currently, when `SPACE` is pressed, the player launches into the air and doesn't come back down. I have tried tinkering with the logic for some time, but can't seem to wrap my head around why it's not working.
Any help is appreciated!
EDIT: it seems as though my player reacts well to the mechanics I have set up... _when_ `SPACE` is held down. As soon as you let go, the player hangs at whatever y-position he is currently situated, and doesn't move until you press `SPACE` again. How do I get him to keep falling even when I let go of `SPACE`? Will that have to be in the `Update()` method? Thanks!

Unity 3D C# dash in backward direction
Hi Ive been trying to get my character to have a "dash" ability to move backwards and cant seem to get it to work.
(I am a high school student with no computer science background so I apologize if i make some easy errors)
so Ive tried some things such as these and tips on how to make it work?
rb.MovePosition(gameObject.transform.position - (Vector3.back * 5));
which got it moving 5 units in a set direction, but not sure how to make this in the "back" direction.

Gravity trouble: Falling slow, jumping fast
I'm a noob so go easy on me.
I'm trying to make a simple jump function. Unfortunately, I go up very quickly and come down very slowly. Code is this:
void FixedUpdate()
{
float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");
Vector3 movement = new Vector3(moveHorizontal, 0.0F, moveVertical);
//Note I'm not adding anything to the y vector here ^
rb.velocity = movement * speed;
if (Input.GetKey("space") && detectGround())
{
rb.AddForce(0.0F, 1000, 0.0F);
//It seems like I'm adding way too much force on y vector, but even with that much I barely leave the ground. I need, like, 10,000 to get a good high jump.
}
}
bool detectGround()
{
Vector3 down = transform.TransformDirection(Vector3.down);
return Physics.Raycast(transform.position, down, .51F);
}
I'm aware that I might run into weird gravity problems if I'm using odd scales, but I'm dealing with a 1x1x1 sphere in this case. Drag is also not the problem (and if it was, why do I go up so fast?). I've also tried adding some weight to my gravity by changing my y vector. That makes me fall faster but doesn't help the jump any.
Interestingly, I don't seem to have this problem if I use rb.AddForce(movement*speed) instead of rb.velocity = movement*speed. Then, however, I don't get the tight control that I want for my X axis and Z axis. (I accelerate too slowly, never hit a peak speed, and have trouble stopping).
How do I fix this?

3D FPS jump mechanic and ground detection
This is a 3D, FPS project.
I only want my character to be able to jump during the frame the character is touching the ground. This appears to be the working correctly when jumping using only the spacebar. This only appears to be true, because the spacebar input can only be sent so quickly - not every frame.
When jumping using mousewheel down, several jump commands are applied to the player, resulting in more vertical force than desired. My assumption is that my player is "on the ground" for more than just a single frame.
I added a Jump Debug variable that constantly sends jump commands to help me inspect what is happening frame by frame. It appears as though my player's collider is some times passing through the ground plane.
- How can I ensure that the player collider does not pass through the ground plane?
- What is the optimal way to detect if the player is in contact with the ground plane?
Below are examples of jumping with the space bar, mousewheel down, and with the Jump Debug enabled.
Also below is the script (C#) attached to my Player.

So, obviously, when character "slips" or "climbs" on the surface his |velocity| < 0.1 and he is not on the ground already and can't jump. Yes, I can remove this if statement, but in this case I will be able to jump, when ground not only under the character, but on the side of his ground points too.
**How can I fix that problem?**
Thnx.

How to stop spam jumping
So I'm trying to make it to where the player cannot just spam the jump so the animation has time to reset, but can't figure out how to do it.
using UnityEngine;
using System.Collections;
public class Character_movement : MonoBehaviour {
public Rigidbody rb;
private Vector2 forceToAdd = Vector2.zero;
private Vector2 jumpForce = Vector2.zero;
public float sideToSide = 10f;
public float maxSpeed = 5f;
public float maxJump = 10f;
static Animator ani_1;
// Use this for initialization
void Start () {
ani_1 = GetComponent ();
}
// Update is called once per frame
void Update () {
if (Input.GetKey (KeyCode.A)){
if (rb.velocity.y > .1f && rb.velocity.y < -.1f)
forceToAdd += new Vector2 (-sideToSide / 10, 0f);
else
forceToAdd += new Vector2 (-sideToSide, 0f);
}
if (Input.GetKey (KeyCode.W)) {
ani_1.SetTrigger ("W_is_held");
}
if (Input.GetKeyDown (KeyCode.A)) {
ani_1.SetTrigger ("A_or_D_is_pressed");
}
if (Input.GetKeyDown (KeyCode.D)) {
ani_1.SetTrigger ("A_or_D_is_pressed");
}
if (Input.GetKey (KeyCode.S)) {
ani_1.SetTrigger ("S_is_held");
}
if (Input.GetKeyUp (KeyCode.A)) {
ani_1.SetTrigger ("A_or_D_is_let_go");
}
if (Input.GetKeyUp (KeyCode.D)) {
ani_1.SetTrigger ("A_or_D_is_let_go");
}
if (Input.GetKeyUp (KeyCode.W)) {
ani_1.SetTrigger ("W_is_let_go");
}
if (Input.GetKeyUp (KeyCode.S)) {
ani_1.SetTrigger ("S_is_let_go");
}
if (Input.GetKeyDown (KeyCode.W)) {
ani_1.SetTrigger ("W_is_pressed");
}
if (Input.GetKey (KeyCode.D)) {
if (rb.velocity.y > .1f && rb.velocity.y < -.1f)
forceToAdd += new Vector2 (sideToSide/10, 0f);
else
forceToAdd += new Vector2 (sideToSide/2, 0f);
}
if (Input.GetKeyDown (KeyCode.W) && rb.velocity.y > -0.1f)
jumpForce += new Vector2 (0f, maxJump);
if (rb.velocity.magnitude < maxSpeed || Mathf.Sign(rb.velocity.x) != Mathf.Sign(forceToAdd.x))
{
rb.AddForce (forceToAdd);
}
rb.AddForce (jumpForce,ForceMode.Impulse) ;
jumpForce = Vector2.zero;
forceToAdd = Vector2.zero;
}
