Returns whether the given argument is a boolean value.



Argument Description
n The argument to check.

Returns: Boolean


This function returns whether a given variable is a boolean (true ior false) or not. In some cases you want to check and see if a variable in GameMaker Studio 2 holds a boolean value, and that's when you would use this function.


if is_bool(val)
   global.Sound = val;
else    {
   global.Sound = true;

The above code checks the variable "val" to see if it is a real number and if it is it then uses it to set a global variable.
