Tag: rendered

I want to create a game object where you can start dragging it by touching the collision line and create those "dynamic shapes" by stretching the sprites and reshaping the look and collision of the sprites according to the handle.

Add an illustration to the share:

Began to play with Sprite Shape Renderer However, to create these bent sprite tiles, I need to be able to create dynamic tiles with the mouse pointer and adjust all collisions.

I tried to add one AnchorDragger Screenplay for Sprite Shape Renderer Object:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.U2D;

public class AnchorDragger : MonoBehaviour
{
    const int INVALLID_INSERTED_POINT_INDEX = -1;

    public SpriteShapeController spriteShapeController;
    private Spline spline;
    private int inseretedPointIndex = INVALLID_INSERTED_POINT_INDEX;

    void Start()
    {
        spline = spriteShapeController.spline;
        int pointCount = spline.GetPointCount();
        for (var i = 0; i < pointCount; i++)
        {
            Vector3 currentPointPos = spline.GetPosition(i);
            Debug.Log("Point " + i + " position: " + currentPointPos);
        }
    }

    // Update is called once per frame
    void Update()
    {
        if (inseretedPointIndex != INVALLID_INSERTED_POINT_INDEX)
        {
            spline = spriteShapeController.spline;
            spline.SetPosition(inseretedPointIndex, Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, 1.0f)));
            // Debug.Log("Setting position to: " + Camera.main.ScreenToWorldPoint(Input.mousePosition));
        }
    }

    void OnMouseDown()
    {
        Debug.Log("Mouse Down Position:" + Input.mousePosition);
        Vector3 mouseDownPos = Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, 1.0f));
        Debug.Log("World Position: " + mouseDownPos);
        spline = spriteShapeController.spline;
        int pointCount = spline.GetPointCount();
        int closestPointIndex = int.MaxValue;
        float minDistance = int.MaxValue;
        for (var i = 0; i < pointCount; i++)
        {
            Vector3 currentPointPos = spline.GetPosition(i);
            float distance = Vector3.Distance(currentPointPos, mouseDownPos);
            if (distance < minDistance)
            {
                minDistance = distance;
                closestPointIndex = i;
            }
        }
        spline.InsertPointAt(closestPointIndex, mouseDownPos);
        spline.SetTangentMode(closestPointIndex, ShapeTangentMode.Continuous);
        inseretedPointIndex = closestPointIndex;
        Debug.Log("Inserted point index: " + inseretedPointIndex);
    }

    void OnMouseUp()
    {
        Debug.Log("Mouse Up");
        spline = spriteShapeController.spline;
        spline.RemovePointAt(inseretedPointIndex);
        inseretedPointIndex = INVALLID_INSERTED_POINT_INDEX;
    }
}

Basically, we tried to find the closest point on the spline I clicked on and then insert a new point and set its position Update to where the mouse is located and delete the point with the mouse upwards.
At the moment I have a problem where the drawing position is not correct for some reason.
Where I clicked, where the new point position is set:

Even as I tried to play with the mouse click and drag, I was not sure why I needed help.

I am also not sure how I would update this EdgeCollider2D? I know, I can get it in the Update Method with:

EdgeCollider2D edgeCollider = gameObject.GetComponent();

But how would I actually update it correctly to fit the new sprite?
