How to mix velocity with addForce?

Questions & Answers

Guys, I have constant movement in the X axis and when jump key is pressed there is an AddForce that adds force to the Y axis, but how can I add force also in the X axis so the jump feels more natural?

I can’t do it right now because o my velocity set is overriding the X addForce.

Here is my movement code:

void FixedUpdate()
	{
		rigidbody.velocity = new Vector3(speed.initialSpeed, rigidbody.velocity.y, 0);
		
		if(!onGround)
		{
			this.rigidbody.AddForce(new Vector3(0,-gravity,0));
		}

		if(jump)
		{
			rigidbody.velocity = new Vector3(rigidbody.velocity.x, 0, 0);
			rigidbody.AddForce(jumpForce, ForceMode.VelocityChange);
			jump = false;
		} 
	}

Thanks!

  1. instead of apply new force instantly, just calculate speed offset needed in whole FixedUpdate method.
  2. at the end of method apply offset with ForceMode.VelocityChange

something like

void FixedUpdate()
{
    Vector3 speedChangeNeeded = Vector3.zero;

    speedChangeNeeded.x = speed.initialSpeed - rigidbody.velocity.x;

    if (!onGround)
    {
        speedChangeNeeded.y = -gravity;
    }

    if (jump)
    {
        speedChangeNeeded.y = jumpForce;
        jump = false;
    }

    rigidbody.AddForce(speedChangeNeeded, ForceMode.VelocityChange);
}
