Hello, I am coming from Unity and am finding something I thought would be a very fast and simple test project rather difficult. I am trying to create a script of circles that detect when they collide with other circles, the larger one will absorb the smaller one. But when I resize the collision circle it just stops working all together. here is my code.
extends KinematicBody2D
var radius = 25
var pos = Vector2(0,0)
var col = Color(0,0,0)
var moveSpeed = 3
var movement = Vector2()
var maxSpeed = 4
var isShrinking = false
var isGrowing = false
func _draw():
draw_circle(pos, radius, col)
pass
func _process(delta):
$CollisionShape2D.shape.radius = radius
$Hit/CollisionShape2D.shape.radius = radius #this is the one with problems
if Input.is_action_pressed("d"):
movement.x += moveSpeed
elif Input.is_action_pressed("a"):
movement.x -= moveSpeed
else :
movement.x = 0
if Input.is_action_pressed("w"):
movement.y -= moveSpeed
elif Input.is_action_pressed("s"):
movement.y += moveSpeed
else :
movement.y = 0
if Input.is_action_just_pressed("ui_up"):
radius += 5
move_and_slide(movement)
update()
if isShrinking:
_shrink()
if isGrowing:
_grow()
pass
func _shrink():
print("SHRINKING!")
func _grow():
print("GROWING!")
func _on_Hit_area_entered(area):
if area.get_parent().radius > radius:
isShrinking = true
elif area.get_parent().radius < radius:
isGrowing = true
func _on_Hit_area_exited(area):
isGrowing = false
isShrinking = false
I cant figure out how to do this, I feel it should be very simple but I cant find anything about this. If you can help me find a better way of doing this I would be very grateful
