How to raise an error with a message?

Another question already asked about raising an error, but their question was really asking how to stop the debugger at a given point. And so the answer addressed that real question rather than how to raise an error (additionally, the question is a few years old now and may hav changed). Is there a way to actually raise an error? Preferably passing an error message? Thank you!

What do you mean by “raise an error”?

I think it’s related to the concept of exception handling, Zylann.

Godot doesn’t suppot exceptions, at least not like common languages do it. It only has asserts or error prints. Is it about the latter?

I think it’s about printing an error. Or more of, when the program is executing, the programmer would like to handle an error the best way they can. For example, what I usually do when I can catch an error, I use the following:

if (foo != "bar"):
    print("It's not a foobar!")

I hope that clears things up.

If you want to have a message appear in godot’s built-in debugging tools, you can do so by “pushing” errors or warnings…

push_warning ( String message )
push_error ( String message )

Here’s a Link to the Documentation.

I hope it’s the same concept you referred to with “raising” warnings/errors.
