Jumping up quicker? (Paper Mario style jump)

Question

As shown here, Paper Mario's jump takes 8 frames go reach the max jump height and 12 frames to get back to the ground. This is pretty unusual, any idea how to jump up that quick with a rigidbody?

I tried to AddForce when rigidbody.velocity.y > 0, but that didn't work out.

Any help would be appreciated, thanks in advance!

//Jump when pressing button and on ground
//jumpForce is a public float variable

if (Input.GetButtonDown("Jump") && isGrounded)
{
    theRB.velocity += new Vector3(0, jumpForce, 0);
}

Answer 1

When jumping, set a flag (e.g., isJumping) that indicates that the player jump is in action. Then, in update make checks if the vertical velocity is negative (falling down) and player is jumping. If it is:

• for Rigidbody2D - reduce rigidbody's gravity scale to 0.67 (8 / 0.67 ~= 12).

• for Rigidbody (3D) - add velocity as such: rigidbody.AddForce(Vector3.up);

When player hits the ground, restore gravity scale to 1 and remove isJumping flag.
