About 'Better CubeDude Movement'!

[Yann_Burrett]

In this video (objectives)…

1 Animate CubeDude 2 Have CubeDude face forwards 3 Make sure diagonal movement isn't faster than cardinal movement

After watching (learning outcomes)…

Make CubeDude move in a more natural and predictable way

I did like the lecture! Using a little vector math and playing animations to make the game look nice in a simple and effective way is just fun

There is one thing that bugs me though:
I think the vector math in the face_forward() function is a little off and you can see that at around 10:30 - 10:50 minutes in the video:
The player rotates around the world origin!
Why is that? You assume that look_at() works in local space, but it doesn’t! look_at() uses global space.
So what do we need to change? We need to add global_transform.origin to the Vector, so we look from where we are to the place where we are going:

func face_forward():
	if motion.x != 0 or motion.z != 0:
		look_at(global_transform.origin + Vector3(-motion.x, 0, -motion.z), UP)

Now, why does the player still look in the correct direction in the video after you multiply the normalized vector by speed? Making a vector longer or shorter doesn’t change its direction at all! Because we now look at a point that is 10 units away from the origin, which is a good enough approximation of the correct direction in our small pitch to not see the problem. Especially when the player is animated as lively as cubedude

If I’m wrong about this and someone knows why, please tell!

Again, having fun with the course, great work and thank you @Yann_Burrett!
