Game Maker help - Gors - 03-30-2016
Hey everyone. I'm having trouble coding something, figured I could get some help
basically it's an app that tests if the number I inserted is even or odd. The coding in GML goes as follows:
Code:
var number = get_integer("Type a Number.",0);
if( is_real(number)== true){
if(number%2 ==0){
show_message("The number "+string(number)+" is even.");
}
else if(number%2==1){
show_message("The number "+string(number)+" is odd.");
}
}
else{
show_message("Insert numbers only.");
}the exact problem i'm having is that currently, I am able to type a word and since GML considers words as "0", the app gives out the even message when it is clearly not even (it's not even a number!!)
If there was a way to limit the input somehow I'd be very grateful.

Googling a little points me to
string_digits(number) strips all letters out
for the sake of testing, have it print out what string_digits(number) returns, if it's completely empty or a 0, if it's completely empty just slap another if in
too lazy to write gamemaker but basically the code after that would look like
>please give numbers (code to get numbers)
>(if using string_digits(number)) hey this isn't a number shithead
>(if it passes, if for even and odd and all that)
