Answer 1

The error message "isnt declared in the current class" means the type of node you have chosen doesnt have this property. A kinematic body would have this property for instance but a basic node wouldnt. What kind of node is your bullet made of?

Answer 2

To fix your error, you need to change node's script owner to Node2D or it's descendants (and add extends Node2D as first line of your script) class.
get_global_position is defined in Node2D class. Based on your script, your node is extended from Reference (if your script has no extends keyword, then your script extends Reference).
