Unity Stretch Sprite between two Points at runtime
How to stretch a Sprite between two points say initialPosition , FinalPosition in world coordinates, Please elaborate with code, Thanks
using UnityEngine;
using System.Collections;
public class Player : MonoBehaviour {
public Vector3 startPosition = new Vector3(0f,0f,0f);
public Vector3 endPosition = new Vector3(5f, 1f, 0f);
public bool mirrorZ = true;
void Start() {
Strech(gameObject, startPosition, endPosition, mirrorZ);
}
public void Strech(GameObject _sprite,Vector3 _initialPosition, Vector3 _finalPosition, bool _mirrorZ) {
Vector3 centerPos = (_initialPosition + _finalPosition) / 2f;
_sprite.transform.position = centerPos;
Vector3 direction = _finalPosition - _initialPosition;
direction = Vector3.Normalize(direction);
_sprite.transform.right = direction;
if (_mirrorZ) _sprite.transform.right *= -1f;
Vector3 scale = new Vector3(1,1,1);
scale.x = Vector3.Distance(_initialPosition, _finalPosition);
_sprite.transform.localScale = scale;
}
}
That worked for med too, though I had to multiply scale.x with 100. Thanks
Worked for me too, i only had to divide scale.y by 100, thank you very mush.
Had to take in consideration the length of the original image and divide by the scale for it to work for me:
float width = obj.GetComponent().bounds.size.x;
Vector3 centerPos = (initialPosition + finalPosition) / 2f;
obj.transform.position = centerPos;
Vector3 direction = finalPosition - initialPosition;
direction = Vector3.Normalize(direction);
obj.transform.right = direction;
if (mirrorZ) obj.transform.right *= -1f;
Vector3 scale = new Vector3(1, 1, 1);
scale.x = Vector3.Distance(initialPosition, finalPosition)/ width;
obj.transform.localScale = scale;
It would be difficult to do it from the sprite, From what I have used with sprites you could change the scale, rotation and position and such to make it fit between two points but using to points to find that would be a little trickier. (I suppose if you wanted to do the math you could derive your own rotation and scales from the two points.)
If a GUI is an option you could use this:
GUI.DrawTexture (new Rect (<X1>, <Y2>, <X1>-<X2>, <Y1>-<y2>), MySprite.texture, ScaleMode.ScaleToFit);
Hope that helps. Cheers, BM
