Debugger / Breakpoints not working

godotboon777

Hi,

i want to use the debugger but when i set the breakpoints (red dots) and run the code the execution is not halting on the breakpoints that i have set. Can anybody help?

Thank you !

Does it seem like it's 1 line off? If so then it is likely halting in the right place, just highlight is off by 1 line. I've seen this myself too, yes.

Remember that breakpoints can only be triggered from the main thread – this is a limitation of the current debugger implementation. This means that code running within Threads will not trigger breakpoints.

Will 4.x remove this limitation?

Or alternatively longer term plans to improve the debugger?

Can you explain more about the problem? Is the debugger halting at all (for example on the wrong line) or is it just playing the game without stopping? Are you certain that area of code is even being executed (e.g. by putting a print statement there)?

The debugger didn't change much in 4.0, except for the editor debugger protocol which now allows running multiple instances and better handles large amounts of data (such as spamming print()s).

Supporting multiple threads in debugging is far from trivial. It's not planned for 4.0, and it'(s unlikely to be done for 4.1 unless a motivated contributor manages to implement it.
