Can confirm that var should be a vector2(0,0), if your confused about what vector is, its how godot and many other game engines handle movement of anything in a space, vector is 3D and vector2 is 2D, a vector in simple forms represents a sort of, point in space, in vector2() the first number represents the x Coordinate which you can imagine being horizontal lines across your screen. The second number is the y Coordinate which you think of being vertical lines across your screen. In 3d its a bit more complex because of the third dimension, it uses three numbers for x,y,z. There's a lot to be covered on vectors and vector math, but right now its important to know that if your doing movement you need a vector. I did have an image on my phone here of the tutorials code but uh. Guess I can't upload it via phone.
