This entry is about the little things before aiming for the control of the puck. In our case, we have decided to use a raycast to check if the player is able to reach the puck, you can see the preparation below:

As you can see, the cast is masked to work only with the puck layer to avoid any confussion with the ground later. The raycast, in charge of this, is called "forThePuck", and it has the enable option checked, with bodies but not areas.
Once we've done that, it's time to make a sanity check before going all out with the puck control and shooting:

Once we've done that, it's time to make a sanity check before going all out with the puck control and shooting:
- Create a new boolean variable initialized at false, this will tell us if the player has the puck or not.
- Now write a function that uses the raycast to know if the puck is at player's reach.
- Then, finally we add code in the loop to manage the actions for "grabbing it" and "shooting it.
[The script below is only printing text to evaluate both situations, but we'll change that with proper methods in the next steps.]

onready var forThePuck = get_node("ForThePuck") # collision layer 2, only the puck
onready var hasPuck = false

var dir = Vector3()
dir.x = Input.get_action_strength("ui_left") - Input.get_action_strength("ui_right")
dir.z = Input.get_action_strength("ui_up") - Input.get_action_strength("ui_down")
apply_central_impulse(dir.normalized() /10)
# Jumping code.
if on_ground() and Input.is_action_pressed("jump"):
apply_central_impulse(Vector3(0,1,0))
# Grab puck control
if puck_on_sight() and !hasPuck:
get_node("Label").text = "goal"
hasPuck = true
if !puck_on_sight():
get_node("Label").text = ""
hasPuck = false
# Test if there is a body below the player.
func on_ground():
if raycast.is_colliding():
return true
# Test if the puck is on sight
func puck_on_sight():
if forThePuck.is_colliding():
return true
```
Besisdes, we're going to change the code to display the direction of the player's movement, we had done that in the vehicle node and script.
This is better and less "hacky":
[Warning: the vehicle node wasn't really needed. We'll be cleaning that when we have the puck control done. Now, this new method (code), however, is valid for both.]
```
extends VehicleBody
# Hacky way to make the character look at directions without breaking movement
# Called when the node enters the scene tree for the first time.
func _ready():
.get_node("WheelRequired").disabled = true
set_disable_scale(true)
func _integrate_forces(state):
var dir = Vector3()
dir.x = Input.get_action_strength("ui_left") - Input.get_action_strength("ui_right")
dir.z = Input.get_action_strength("ui_up") - Input.get_action_strength("ui_down")
# look at aiming direction properly / still needs a few touches
look_at_from_position(get_global_transform().origin, dir , Vector3.UP)
```
