variable_global_exists(name);
| Argument | Description |
|---|---|
| name | The name of the global variable to check for (as a string) |
Returns: Boolean
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")) global.enemy_num = instance_number(obj_Enemey_Parent);
The above code will check to see if the global variable called "enemy_num" exists and if it does not it is created and set a value.
