With this function you can check whether a variable exists within the given struct or not. You supply the struct reference to use as well as the variable name to check for as a string (see example code below). The function will return true if a variable with the given name exists for the struct and false otherwise.
variable_struct_exists(struct, name);
| Argument | Description |

Boolean
if !variable_struct_exists(mystruct, "shields"))
