Scaling line as i pull it (rubber band)

LinasJaniques

Hello guys

So i'm making a game in wich I have a line with an end atatched to a square and as I move the square, that end of the line should move with it. And I did that using the pinJoint.

Ok, but now I need this line to scale up and down as I pull it or get closer to it, like a rubber band. How can I do that?

As you can tell, I'm new to this whole programming and making games thing, I always try not to post on forums 'cause I wanna figure it out by myself learning from mistakes, or just googleing it... And I've tried, but I just don't know what I'm looking for, exactly. So can you guys help me?

I've thought of getting global position of both squares, subtracting it and then setting that result as the scale of the line, but i guess that's just wrong haha.

Sorry if there's already a question about it.

Thank you all.

You weren't far off with that at all - you probably want to:

~~1. Get the result of subtracting one square's position from another.~~ ~~2. Get the length of that vector.~~ 1+2. Get the distance between the two squares using distance_to. 3. Set the line's thickness to be 1 / that vector's length, so that the line gets thinner with distance. How exactly you set that thickness depends on the kind of Node it is.

From there, you should basically be able to tweak stuff to get the result the want.
