Why is this showing an error? Any idea on how to fix this?

Adam

BTW dead-sprout is an enemy. Any help will be appreciated!

That error message is saying that the parameter body is a String, and the String class doesn't have a method is_in_group().

The cause of the error is that you're calling that function in _physics_process() with the String parameter "body".

Even if i call it in ready(), it shows the same error. Where should i call it then? If i get rid of the body argument, then this function is gonna be useless.

The function is correct. But you are calling it with the String named "body" not an actual physics body, which makes no sense.

DaveTheCoder

That function looks like a signal handler, which you would not call. Rather, it's called by the engine when the signal is emitted. The nodes deadsprout and Area2D have signals connected. Maybe one of those signals is connected, or should be connected, to that function?

Also, the function doesn't do anything. It declares two local variables and gives them values, but doesn't use them.

I don't get what you mean by that (I am a Godot and game-developement beginner as this is my first game). Isn't body storing the information about the collider or something like that(I might be wrong).

Those variables will be used later on in physics process when i implement knock-back,damage,etc. But after putting is_hit = true in that function to change the bool of is_hit, i found out that this function isn't working. It didn't change the is_hit bool to true whenever the area 2d should is triggered.Edit: I don't know if something is wrong with the signal. Is there a way to test it?

Adam

These images will hopefully help you understand this problem. Dead-sprout is an enemy and is in the enemies group. The level-1 scene is where i was testing the is_hit variable(look at my reply on DaveTheCoder's comment. And finally as you know, the player scene is where the problem is.)

The difference is that rather than providing a variable that holds a reference to the physics "body" you are providing a variable that holds a string(text) that has the characters "body" in it.

see line 32 in your original screenshot in OP. You are literally inputting a string that holds " body " in it.

I would recommend reading this book: https://www.amazon.com/Godot-Engine-Game-Development-Projects-ebook-dp-B079HZD1S7/dp/B079HZD1S7

OK, if you say so. I am not gonna deny that i do need to learn more about Godot. I am gonna pause the development on my project and read this book fully. Thanks BTW. I hope this book is worth it. edit: I was searching for a book myself.

Yeah, I can explain what is wrong with your code, but it is very fundamental to programming and it would be a long post. I take it you are a beginner, so reading that book will help you more get to a place where you can finish your game.

OK so ummmm, while reading the book, it told me how to use area 2d's signals. While reading that i realized that i was using the body entered signal while i should be using the area entered signal. That fixed it and it works now but still I am just gonna keep reading the book to learn more about Godot. I was being way too dumb.

cybereality

Nice, you actually got the book. Sometimes I wonder if people take my advice.
