How to I make something rotate in the direction it is moving? (2D)

justin-todd

How would I replicate a behavior like this in Godot? <blockquote class="imgur-embed-pub" lang="en" data-id="a/8N314Lc" >Player rotates in direction of movement</blockquote><script async src="//s.imgur.com/min/embed.js" charset="utf-8"></script> I already have a movement system, I just cant figure out how to do the rotation.

Welcome to the forums @"Justin Todd"

~~If you have a Vector2 for movement, then you can convert it to rotation using cos and sin:~~

var velocity_norm = velocity.normalized()
rotation = cos(velocity_norm.x) + sin(velocity_norm.y)

Edit: Sorry, not cos and sin, you need to use Atan2:

var velocity_norm = velocity.normalized()
rotation = atan2(velocity_norm.y, velocity_norm.x)

I don't know what I was thinking with my original post. You can use cos and sin to convert a angle to a vector, but that's not what you are looking for (nor what the code I originally wrote would do) :sweat_smile:

Easiest way is to orient it conditionally according to movement key inputs, that is counting also 2 key combos. So basically "8-axis" movement. Or if you want to make it smooth just create another object that moves in front(along positive x axis local to tank) of it and then change it's orientation via look_at.
