add or subtract to a point with the same key (Answered)

Mentiras

I am trying to work out how to make a variable angle to eventually be used in a show projected angle display. I can not seem to figure out how to get the number to subtract after reaching its upper limit. Here is what I have so far.

extends KinematicBody2D

var angle = 0
onready var label = $Label

func get_input():
	if Input.is_action_pressed("f"):
		if angle <= 88:
			angle += 1	
		
func _physics_process(delta: float) -> void:
	get_input()
	clamp(angle, 0, 89)
	label.text = str(angle)

has no problem getting to and stopping at 89, but I can not get it to go back down to zero while holding the same action key.

Try adding the following after line 9:

        elif angle == 89:
            angle = 0
        else:
            print("angle out of range on KinematicBody2D")

Ah, or if you want to do the same thing backwards you could do this:

extends KinematicBody2D

var additive = true
var angle = 0
onready var label = $Label

func get_input():
    if Input.is_action_pressed("f"):
        if angle <= 88 and additive:
            angle += 1
            if angle == 89 and additive:
                additive = false
        elif angle >= 1 and !additive:
            angle -= 1
            if angle == 0 and !additive:
                additive = true
        else:
            print("Angle is out of range on KinematicBody2D")
        
func _physics_process(delta: float) -> void:
    get_input()
    clamp(angle, 0, 89)
    label.text = str(angle)

edit: forgot to add the state change. :tongue:

I could use that, but what I was really looking for was something that would take the numbers like this: 85, 86, 87, 88, 89, 88, 87, 86, 85 etc. I want the dotted line to sweep back and forth until the player releases the key. As it stands, the line will jump back to 0 =)

Thank you though. I do appreciate the help.

LOL thank you, how do I set the last reply as the answer?

Since they have been marked as rejected answers, they need to be reset before they can be marked as the answer. Since I'm not sure which exactly you want to mark, I reset all of the replies :smile:

Thank you.
