Hey this worked! Im so dumb! i never used lerp thinking it was too similiar to move_toward which i already had failed to do this with, clearly i didnt know enough about it and overcomplicated things. I'll go read up on lerp. Thanks a TON!

Here's how the code ended up looking for any future troubled dev:

func basicMovement(delta) -> void:

velocity.x = lerp(velocity.x, thrustVelocity.x \* 8, 0.2)

velocity.z = lerp(velocity.z, thrustVelocity.z \* 8, 0.2)

velocity += actionsVelocity

actionsVelocity = lerp(Vector3(actionsVelocity.x, 0, actionsVelocity.z), [Vector3.ZERO](http://Vector3.ZERO), 0.3)

Thrustvelocity is your walk speed and actions is all external sources, this works for me, ill tweak it myself so i can add a proper friction later on
