Question by kamuzai1226 · Mar 21, 2014 at 07:36 AM · 2d-platformerladder

2d Ladders snap to middle?

So far I am able to go up and down the ladder and move left to right on it, but what I want is for the character to snap to the middle of the ladder in order for me to synchronize animations properly. How would I go about doing this?

How about getting the center of the ladder object and using that ?

For example, if ladders only go up in a straight line, you could just use something like

 Vector3 center = new Vector3(ladder.transform.position.x, 0,ladder.transform.position.z);
 player.transform.position = new Vector3(center.x, plater.transform.position.y, center.z);

^thats just an example, probably wouldn't look so pretty if the character would snapp to the position

This is what I was trying to do, find the center of the ladder sprite and just move the character to the position. $$anonymous$$aybe I could do this with a mathf lerp so it isn't like a teleport, but more of a smooth movement.

Would you know how to do this?

https://docs.unity3d.com/Documentation/ScriptReference/Vector3.Lerp.html

would probably do the trick.. so something like

 Vector3 ladder = new Vector3(ladder.transform.position.x, 0,ladder.transform.position.z);
 Vector startPosition = player.transform.position;
 player.transform.position = Vector3.Lerp(startPosition, ladder, fracJourney);

sorry for not giving a full sample :)

If you are controlling your player with physics, I'd recommend doing this in the FixedUpdate loop, no need for lerping.
