var leftCollider = Rect2(get_node("leftplayer")get_poss() - pad_size * 0.5, padsize)

Hi Friends This code works in Godot 2 but how does it work in Godot 3?

get_pos() was replaced by the position property:

var leftCollider = Rect2(get_node("leftplayer").position - pad_size * 0.5, padsize)

Identifier ‘pad_size’ is not declared in the current scope

Ne diyorsan onu yaptım bu hatayı alıyorum.

pad_size has never been a built-in variable in Godot 2, it must come from your game. Check if you declared that variable.

var padsize

 func _ready():
screenSize = get_viewport_rect().size
padsize = get_node("rightplayer").get_texture().get_size()
set_process(true)
pass

Specified in this way

 var padsize
 padsize = get_node("rightplayer").get_texture().get_size()

It could also be that you made a typo, you wrote padsize but the error says pad_size.

Yes There is one more thing I want to say correctly Rect2

var leftCollider = Rect2(get_node("leftplayer").position - pad_size * 0.5, pad_size)

There is an error in Rect2

position - pad_size * 0.5

What is the type of pad_size? It has to be a Vector2 otherwise it won’t work.

Code worked when pad_size

var leftCollider = Rect2(get_node("leftplayer").position - pad_size * 0.5, pad_size)

Now there is an error in Rect2

What is the error?

Zylann | 2019-08-21 19:47

	var leftCollider = Rect2(get_node("leftplayer").position - pad_size * 0.5, pad_size)
var rightCollider = Rect2(get_node("rightplayer").position - pad_size * 0.5, pad_size)

if(leftCollider.has_point(get_node("Ball")) or rightCollider.has_point(get_node("Ball"))):
	ballDirection.x = ballDirection.x

I get this error

İnvalid type in function ‘has_point’ in basa ‘Rect2’. Cannot convert argument 1 from Object to Vector2.

has_point(get_node("Ball"))

Godot is telling you has_point expects a Vector2. get_node("Ball") is not a Vector2, it’s a Node. You may want to do get_node("Ball").position instead.

Same as in A code error in Godot 3 - Archive - Godot Forum
