Juane Gray - Higgins: Sketch #26 Vertex Offset

So, here I am again my goal is to make guts fall from a zombie character I have laying around, and with it comes some squash and stretch guts and organs that fall out of it.

How am I going to do it? I have no clue. I guess you and me will find out!

So to start off I watched a bunch of videos, messed around with a lot of shader things (rotate about axis) (could not get it to work) so I tried another method. this time I started from scratch.

So I came up with the idea to pass the collision point of the object into a space local to the object.


Something like this or similar, and I wanted to get the result of this

Which I somehow of a miracle made happen:

and with that comes the shader: although I could not get rotation to work it’s definitely a step in the right direction!

So today I managed to get rotation working, by simply changing two inputs and converting to world/object space! I am so blind!

Here is what the shader looks like now:

Code related:

private void Start()
{
    rend = GetComponent<Renderer>();
    RB = GetComponent<Rigidbody>();
}

private void Update()
{
    rend.material.SetVector("_ContactPos", toPoint);
    if (!colliding && collisionPoint != Vector3.zero)
    {
        spring2 = 0f;
        spring += Time.deltaTime;
        toPoint = Vector3.Lerp(collisionPoint, Vector3.zero, spring);
    }

    if (colliding)
    {
        spring2 += Time.deltaTime;
        toPoint = Vector3.Lerp(toPoint, collisionPoint, spring2);
        if (toPoint == collisionPoint) { spring2 = 0f; }
    }
}


public void OnCollisionStay(Collision collision)
{
    colliding = true;
    ContactPoint contact = collision.GetContact(0);
    point.position = contact.point;
    collisionPoint = -point.gameObject.transform.localPosition;
    Vector3 dir = transform.position - collisionPoint;
    directionPoint = dir.magnitude;
}

public void OnCollisionExit(Collision collision)
{
    spring = 0;
    colliding = false;
}
}

Awesome!

It does really feel like a soft body simulation :new_moon_with_face:
