8-way movement-movement instrucion override

Zizico2

Hi guys! I'm making a game with top down (eagle eye) vision. I want to make it so that sayyyyy, i'm pressing left arrow and i start pressing right arrow at the same time. I wanna make it so that the latest instrucion overrides the 1st One, so, in this example, the character would start moving right instead of stopping, which is what is hapenning now. Can you help me?!

You should be able to do it with code like this (not tested): extends KinematicBody2D const SPEED = 20 var movement_vector = Vector2() func _physics_process(delta): movement_vector = Vector2() if Input.is_action_pressed("up"): movement_vector.y = -1 if Input.is_action_pressed("down"): movement_vector.y = 1 if Input.is_action_pressed("left"): movement_vector.x = -1 if Input.is_action_pressed("right"): movement_vector.x = 1 " Do whatever you need to do with the input. " move_and_collide(movement_vector * SPEED * delta)

You can change the order of which action takes priority by changing the order of the input checking if statements.

The code above does not override the previous input though. For example, if you use the code above and are pressing down and then press up, the player will continue to move down since the down action always takes priority over the up action.

You could probably make a system that always overrides the previous input, but right off I'm not sure how to go about it without making a project and testing.

Yeah I had gotten that far. The only way I see it is saving the latest different instrucion in a variable and then making a ton of conditions. That's way too crappy of a solution though.

You can monitor events using _input(event) and change your movement vector when a new pressed input arrives by checking if event.is_pressed. You might also need to check if all inputs are not pressed to stop movement when nothing are pressed.

something like this:

extends KinematicBody2D

var movement_vector = Vector2(0, 0)
const SPEED = 20

func _physics_process(delta):
  move_and_collide(movement_vector * SPEED * delta)

func _input(event):
  if event.is_pressed():
    if event.is_action("up"):
      movement_vector.y = -1
    elif event.is_action("down"):
      movement_vector.y = 1
    if event.is_action("left"):
      movement_vector.x = -1
    elif event.is_action("right"):
      movement_vector.x = 1
  if not(Input.is_action_pressed("up") or Input.is_action_pressed("down") or Input.is_action_pressed("left") or Input.is_action_pressed("right"):
    movement_vector = Vector2(0, 0)
