puzzel drop smoothly.

Questions & Answers

what is a good way to create smoth dropping objects in unity.
I created a game where I have spawners that drop blocks if the blocks below are less then count but it uses
unity physics engine and its needs spaces between blocks or else they collide with each other.

this is not practical because I want to create blocks in grids and drop them smoothly and quickly.
they need to stack on top of each other… kind of like a match 3 game.

how do I do this in unity ?
any examples available ?

thx

iTween is exactly what you need.
You can download it for free through the Asset store.

Here’s an example of how to use it, the syntax is a bit overwhelming at first.
This will move a gameObject to another position smoothly over 1 second.

iTween.moveTo(gameObject, iTween.Hash("time",1,"position",newPosition));

Using physics for this game mechanic might not be the best choice, but you can make it work. It is easiest if your blocks are one unit square (1x1x1) and that you launch your block on the 1 unit grid (i.e. directly above a potential stack of blocks). Make your collider for the blocks just a bit smaller than the block (.999,.999,.999). Then put this in a script on your block prefab:

function OnCollisionEnter() {
	rigidbody.isKinematic = true;
	transform.position.x = Mathf.Round(transform.position.x);
	transform.position.y = Mathf.Round(transform.position.y);
	transform.position.z = Mathf.Round(transform.position.z);
}
