# How to assign a type "float" to a Vector2?

Attention Topic was automatically imported from the old Question2Answer platform.

Version 3.5.1, it’s giving me this error at two places the first at
“velocity = calculate_move_velocity(velocity, direction, speed)”
and
“new_velocity =+ gravity * get_physics_process_delta_time()”
I’m following GDQuest’s First 2D game tutorial and he didn’t get this error but his version is outdated so does anyone know how I would fix this?

Hard to tell without seeing the code for the functions `calculatemovevelocity() and getphysicsprocessdelta_time()` but one error here is using `=+` instead of `+=`.

e.g. it should be `newvelocity += gravity * getphysicsprocessdelta_time()`

Also to make your code more readable, try using snake_case for your functions names like: `get_physics_process()`

I was fiddling around with the + which is why it ended up where it is and I do use snake_case. It didn’t transfer over and I didn’t notice until now but for the functions

``````func _physics_process(_delta: float) -> void:
var direction: = get_direction()
velocity = calculate_move_velocity(velocity, direction, speed)
velocity = move_and_slide(velocity,Vector2.UP)
``````

and the other is

``````func calculate_move_velocity(
linear_velocity: Vector2,
direction: Vector2,
speed: Vector2
) -> Vector2:
var new_velocity: = linear_velocity
new_velocity.x = speed.x * direction.x
new_velocity += gravity * get_physics_process_delta_time()
if direction.y == -1.0:
new_velocity.y =  speed.y * direction.y
return new_velocity
``````

When pasting code into the forum, you need to:

• paste the code block
• select it
• press the `{ }` button in the forum editor’s mini toolbar to format it as `code`

Otherwise, weird things happen - including the underscores in snake-case code being interpreted as italics markup.

thanks, probably wouldn’t have figured that out.

Is `gravity` a vector?

It looks like the line `new_velocity += gravity * get_physics_process_delta_time()` is trying to add a float to a Vector if gravity is a float.

e.g. if `gravity * get_physics_process_delta_time() = 5`
Then you’re trying to do:
`Vector2 = Vector2 + 5`
Which causes an error, instead use `new_velocity.y`

`new_velocity.y += gravity * get_physics_process_delta_time()`

Yep that did the job, thanks a lot.
