Unity transform.LookAt in only one axis

问题:

I've been working on a game and it's going really nice. Got some help from here and I need it again. So I'm making a 2D top-down shooter and I need my enemy to look at the player, and obviously the enemy will rotate in all axis and thus being invincible or will look really weird. So, how do I make it rotate only in the Z axis ? Also if you are going to provide and answer I need it done in UnityScript.

回答1:

You just need to set a fixed value at the axis that you don't want to move.

Example, LookAt moving only the Z axis:

var adjusted= target;
adjusted.x = 0;
adjusted.y = 0;
transform.LookAt(adjusted);

If you had made a quickly search on google, you would find it.
