I want to change the frame of instance such that any newly created ones have a difference frame. the issue is in the line $coffeeliquid.frame = Global.Currentdrink.
I keep getting this error:
Invalid set index ‘frame’ (on base: ‘null instance’) with value of type ‘int’.
I’ve been stuck on this problem for a while now. what can I do?
The node you have as the root node of the scene is the same one the script is on?
$Drinkjug points to a Node that does not exist, thus becoming null at runtime, giving you that error.
Either add the Node named Drinkjug or remove that line.
the part that’s not working is : $coffeeliquid.frame = Global.Currentdrink
Drinkjug is in another scene and it doesn’t give any errors.
So there is no node that has both coffeeliquid and Drinkjug as direct children?
yes, there is no node that has both coffeeliquid and Drinkjug as direct children .they are in two different scenes
The $ syntax is just shorthand for get_node() and thus expects the Node to have the name after the $ symbol. If that node doesn’t exist in the current node tree the script is attached to, it becomes null.
so how can I change it? do I put Drinkjug and Coffeeliquid as direct children under a node
It depends on what you intend to do. I can’t make a guess, you gotta tell me.
You can check for null with if variable == null
I want switch the animation frame of instances of Coffeeliquid based on the current value of a global variable. The drinkjug part isn’t very important, but even when I delete it, it still gives me the (Invalid set index ‘frame’ (on base: ‘null instance’) with value of type ‘int’.) error. I cant seem to animate an instance at all
Huh, post the code as it is now, im not sure what you mean, but I have ideas.
And what happens when you click on the error you get?
Show the node tree that contains a node named “cup”
@Efi thank you so much btw. I’ve just started godot, and everything seems hopeless
and that scene is an instance of “coffee.tscn”? If not, did you mean to have a different script on it?
Everything seems hopeless because of capitalism. That is mostly unrelated to Godot.
cup is a scene for where the drinkjug node is. it has the same script as the coffeeliquid node in coffee.tscn.
