Failing at making a nice rigidbody jump, please help!

[anon_38064576]

Hey guys.

Im trying to make some kind of a 2D game as a learning project. I’ve tinkered a bit with the movement, and I’ve figured out the forwards and backwards motion with a rigidbody.

Now I’m trying to get the rigidbody (just a cube) to make a jump, but as I modified the drag to make the forward/backward motion more smooth, the jump also gets a drag, making the fall down REALLY slow lol.

I dont really know how to get around this, does any guru have some sympathy with me and want to help hehe?

Here is my code.

var leftSpeed : float = 80.0;
var rightSpeed : float = 80.0;
var jumpHeight : float = 500.0;

function Update () {

if(Input.GetKey(“a”))
rigidbody.AddForce(Vector3(0,0,-leftSpeed));

if(Input.GetKey(“d”))
rigidbody.AddForce(Vector3(0,0,rightSpeed));

if(Input.GetKeyDown(“w”))
rigidbody.AddForce(Vector3(0,jumpHeight,0));

}

TL;DR

How to make the rigidbody fall faster, without reducing the drag so my forwards and backwards motion doesnt get screwed.

you could put a constant force on it with a -y

Thanks for the idea. I will try this!

Well, it works as intended, forces the rigidbody downwards, however, it also impairs the forward/backward movement.

I can fix this by increasing the forces applied onto the rigidbody, but I dont like the way it works when the rigidbody is in a free fall.

The extra forces on the back/forth movement makes it extremely fast moving in midair because there is nothing to counterwork the forces, you know.

I might just make it so that you cant move back/forth while in mid air, but I dont know how to do it?

Any help?

var leftSpeed : float = 80.0;
var rightSpeed : float = 80.0;
var jumpHeight : float = 1000.0;

function Update () {

if(Input.GetKey(“a”))
rigidbody.AddForce(Vector3(0,0,-leftSpeed));

if(Input.GetKey(“d”))
rigidbody.AddForce(Vector3(0,0,rightSpeed));

if(Input.GetKeyDown(“w”))
rigidbody.AddForce(Vector3(0,jumpHeight,0));

Okay, I increased the jump height, and tinkered a bit with the mass and drag of the rigidbody, it works like a charm now.

Still got the flying fast as hell in midair. How can i make it so that if i use w+a or w+d at the same time, it wont move back and forth? Or just something that makes it unable to move while in midair, and only when on the ground?
