Classic LLM stuff:
Perplexity's response to
"In godot, how can I get the effect of call_group but with return values?"In Godot, you can use the call_group_flags function to call a method on a group of nodes and retrieve the return values. The call_group_flags function takes an additional argument flags which is a bitmask of flags that control the behavior of the function.
This is, of course, a lie.
call_group_flags returns void, just like call_group. It did predict the answer people wish were real, though.
