A grapple hook made by line renderer that has two different textures

So im basically doing a grappling hook using distance joint and a line renderer but i dont want it to be simply a line, i want to make it a hook/dagger that extends till it hits the enemy

so i have this sprite of a dagger that i want only the middle part to be tiled as it stretches
same way it happens when you use it in a sprite shape like this

any tips or ways to make this happen ?

 

What exactly do you need help with?

It sounds like you have half of the work already done.

Are you asking how to make the line renderer look like the sprite shape? Why don't you use sprite shape (which you have already working) instead of line renderer?

Are you asking how to implement the distance joint part? Are you asking how to implement the shooting part?

 

I cant control the sprite shape’s starting and ending point like line renderer i have everything implemented except i want the line to look like the bottom photo with the line texture tiling the middle part only

 

There are no problems changing sprite shapes points using script. You just need to use the correct API. See "SimpleDraw" and "Sprinkler" examples from extra scripts. That should get you started. And for more details and list of all the available methods read https://docs.unity3d.com/Packages/com.unity.2d.spriteshape@1.0/api/UnityEngine.U2D.Spline.html .
