variable_global_exists(name);
| Argument | Description |
|---|---|
| name | The name of the global variable to check for (as a string) |
Returns: Value (any data type) or undefined (if the named variable does not exist)
With this function you can check whether a global scope variable
exists or not. You supply the global variable name to check for
as a string (see example code below) and the function will
return true if a global variable with the given name
exists or false otherwise.
if variable_global_exists("enemy_num")
{
show_debug_message("enemy_num = " +
string(variable_global_get("enemy_num"));)
}
The above code will check to see if a global variable exists and if it does then it is output to the console.
