is_vec4(n);
| Argument | Description |
|---|---|
| n | The argument to check. |
Returns: Boolean
This function returns whether a given variable is a 4 value
vector or not. In some cases you want to check and see what data
type a variable holds in GameMaker Studio 2 and that's when
you would use this function. It returns true or
false depending on whether the value is an int64 or not.
For further information on data types see here.
if !is_vec4(val)
{
show_debug_message("Not a 4 value vector!");
}
The above code checks the variable "val" to see if it contains a vec4 and if it is not then it shows a message in the debug console.
