now, ive ben searching for I while, and I cant seem to find a simple answer. what is a simple way to make a jump pad that uses a character controller and not a rigidbody? (written in C#) I want my character to get boosted into the air when he collides with a specific game object. the script my character is using already has gravity so all I need is an upward boost. does anyone know how to do this? I dont have any code I dont know where to start, so please help!
Did you try Dotween functions? or did you try to change transform.position in Update using your skills.first I would try Dotween functions like Dojump or DoMove, Secondly I would try this ; transform.position + = Vector3.up * Time.deltaTime;
So, you have a player, he has movement and you want him to jump when he touchs a jump pad. So you need to have a CollisionScript for the player as well as a Impulse on the jump pad. My simplistic way to this, is...
Before you use this script you need to create a tag called probably jumpPad and then add it to your jump pad in the scene.
Then I would do the Collision Script, that will detect the collision when the player collides with the jump pad. And get the impulse towards y-axis on collision.
Collision Script:
public Rigidbody playerRb;
public float jumpForce = 10f;
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.CompareTag("jumpPad"))
{
playerRb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
}
}
Then you just need to drag the player Rigidbody for the CollisionScript.
It will look like this

I write character controller script, and implemented moving by changing rigidbody.position, and when my character try move forward close to the wall, he falls a little into incline wall and floor.Character already in another collider ( i held right arrow)
I try make a cast and check if player collider are collide if he moves, but i think that bad resolve my problems , because it create a problems if i want move item by character body and etc.
I think it be possible reslove with unity rigidbody setting or a bit of code
My movement code:
public void Move(Vector2 direction)
{
Vector2 directionAlongSurface = _surfaceSlider.GetDirection(direction.normalized); // It get direction if player try walk on a slope (forward - Vector2.Dot(forward, _normal) * _normal;)
Vector2 offset = directionAlongSurface * (_speed * Time.deltaTime);
//var colliders = Physics2D.BoxCastAll(_boxCollider.transform.position, _boxCollider.size, 90, offset, offset.magnitude,_layerMask);
//if(colliders.Length == 0) //
_rigidbody.position += offset;
}
P.S Character collider a bit goes inside even in a flat wall
a) In your movement code, you are moving the Rigidbody with _rigidbody.position += offset;. This is an incorrect way of moving a physics object. try instead,
rigidbody.MovePosition(rigidbody.position + offset);
b) You might also want to check your Rigidbody settings, the Collision detection modes, to be exact. if you were to use fast moving GameObjects, you'd want Continuous collision detection mode instead of discrete.
I have been looking around for ages about how to do a Real-time Strategy camera for Unity in 2D. What I mean is that you should be controlling the camera with W, A, S, D and where ever I look its only 3D. I have been trying to write my own scripts but the camera never works and I am in dire need for help. I have tried so much but as a beginner on Unity, I really need help with this. If you can give me anything about how to get started in this matter I will be so happy.
Do you think I should use the Force method or that I should use another one that unity already has installed? I also tried using vectors but when I looked around everyone was using Vector 3 which only is for 3D unity.
You can attach a single script to your camera.
public float speed =10.0f;
void Update()
{
Vector3 a = transform.position
if(Input.GetKeyDown("W"))
{
a.position.y += speed *Time.deltaTime
}
if(Input.GetKeyDown("S"))
{
a.position.y -= speed *Time.deltaTime
}
transform.position =a;
}
You can adjust the speed to your needs. You can do this for other keys. Note GetKeyDown is called when a key is being held down. Hope this helps.
Make a direction vector with Vector3 direction = new Vector3();
Manipulate the vector in the directions you want, based on the key:
if (Input.GetKey(KeyCode.A))
direction += Vector3.left;
Adding the "built-in" Vector3.left will point the direction of the vector to the left, and you can add the other keys on top of that to get a final direction.
Then you can use transform.Translate() to move the gameObject (in this case you attached it to your camera) by passing the direction you calculated based on the keys being pressed as a parameter. Then multiply to get direction * speed * Time.deltaTime;
In my 2D side-scrolling game I move my character using the built-in physics engine by manipulating the rigidbody.velocity.
I would like to add some sort of dodge (roll) ability, where the character moves 3 units in its direction.
Here is the code I used:
void FixedUpdate() {
if (Input.GetKeyDown(KeyCode.A) ) {
Vector2 pos = rb.position;
pos.x -= 5;
rb.MovePosition (pos);
}
}
This method works but the character kind of jumps to the position rather than moving to it (Lerping?) and also doesn't detect collisions despite the body type being dynamic.
Then I tried this:
if (Input.GetKeyDown(KeyCode.A)) {
rb.AddForce(new Vector2(-50, 0));
}
I found the AddForce way isn't accurate at all.
Is there a proper way of doing this?
Maybe you could change the Transform.pos inside Vector2.Lerp to make it look smooth? (Sorry, not enough experience with 2D in unity.)
Just increase rigibody.velocity for a set time. Your chararter object could then play a fitting aniamtion. If The player should not be able to cancle midrole jsut block the controls for that time.
I have found a solution for this if I were to be using translation as a means of movement:
http://answers.unity3d.com/questions/1035804/how-do-you-make-an-omnidirectional-2d-character-co.html
however I cannot find a solution for how to do this with my movement being physics based.
I have in my chracters controller the ability to rotate the camera around the z axis:
public Transform target;
private float cameraRot = 3;
if (Input.GetKey("q"))
{
target.transform.Rotate(0, 0, cameraRot);
}
I then have a script on all sprites in the world I am creating that rotates to always face the camera:
public Transform target;
void Start () {
target = GameObject.Find("MainCamera").GetComponent<Transform>();
}
void Update () {
if (target != null)
this.transform.rotation = Camera.main.transform.rotation;
}
That all works fine. However when I have rotated the camera, and therefore the sprites. The rigidbody movements become all skewed as they are rotating in the "global" space and not the "local".
I have tried placing the facecamera script on the child objects only to leave the rigidbody alone but this has no effect.
I hope I made this clear enough and that someone can help.
thank you very much for your time, if I find a solution I will mark the answer as correct and if I fix this myself before an answer I will update with how I fixed it.
The solution was to use:
Rigidbody.AddRelativeForce(Vector2.down * speed);
in lieu of:
Rigidbody.AddForce(Vector2.down * speed);
that adds the force in the local axis not the global.
documentation is here:

I am currently working on a football game(American) and im working on a tackle mechanic. Now just having 2 things bumping into each-other did not work because the character would continue to move after being forced sideways on the ground. To make the character stop after making contact with the other rigid body, I thought the best way would be to use Time.Timescale = 0; . However the problem with this is the fact that the 2 rigid body's then just go through each-other.to solve this I think the best way would be to set time scale to 0 after 1 second of collision. How can I do this?
Feedback is always appreciated ;)
to invoke a method delayed within unity presuming it is a monobehaviour.
the Invoke method apears to be what you are after
http://docs.unity3d.com/ScriptReference/MonoBehaviour.Invoke.html
however please be aware that Time.Timescale effects everything and is not local and would more than likely not get the effect you are after. setting the Velocity of the gameObject to zero should get the desired outcome.
var rb = GetComponent<Rigidbody>();
rb.velocity = Vector3.zero;
Time.Timescale would effect your whole game.
Actually Time.Timsescale is
The scale at which the time is passing. This can be used for slow motion effects.
When timeScale is 1.0 the time is passing as fast as realtime. When timeScale is 0.5 the time is passing 2x slower than realtime.
When timeScale is set to zero the game is basically paused if all your functions are frame rate independent.
From Unity Documentation
Well, what you can do is,
In script attached to Rigidbody's GameObject you can implement OnCollisionEnter.
Rigidbody _rb;
void Start()
{
_rb = GetComponent<Rigidbody>();
}
void OnCollisionEnter(Collision col){
_rb.velocity = Vector3.zero;
}
It will stop your player even after collision with ground. :)
So you can further modify collision condition like if body strikes to some specific object, you can detect it by tag or some other properties.
void OnCollisionEnter(Collision col){
if (col.gameObject.tag == "TAG_OF_SPECIFIC_OBJECT")
_rb.velocity = Vector3.zero;
}
