Hey guys, I'm wondering if there is a way to fix this. So, I got my "Money" as a textNumber(I know its not the best way to go about it) And I have it so When I kill an enemy I have a chance to obtain a random amount of money, like this.

Code: Select all

GETMONEY=rand(5);

if(GETMONEY==0)
{
    Money.textNumber+=rand(100);
}


What I'm having problems with, is that I'm not getting a whole number. I keep getting numbers like "25.50645". Is there a way so it's just Whole? like "25". The fraction is annoying haha.

Thank you!

First off, textNumber is not a replacement for a real variable. textNumber has been known to cause bugs when used like that. The only way you should use it is setting it equal to another variable. In fact, doing so will fix your problem. If you use an integer variable for money, it won't be a floating point. If you feel like taking your chances with using textNumber instead of a real variable, you should use ceil(rand(100)) instead of rand(100). This will round the result of rand up to the nearest integer.

Thanks Sky, That did the trick.

You should always try to make your values variable related, that way if you come to a certain point in development where you wish to save the value, it would be easy to do so rather than changing codes related to the textNumber into variables.

Thanks Savvy, I really do need to practice this more often.

Oh, just occurred to me, if you really don't want to use a variable, what you can do is this:

Code: Select all

int i; //Goes at the very top of your script
GETMONEY=rand(5);

if(GETMONEY==0)
{
    i = Money.textNumber+rand(100)
    Money.textNumber=i;
}

Well that still breaks the rules about not using textNumber like a variable. Also, the int i can go after the first open paren, since it is only used within the if.

Code: Select all

GETMONEY=rand(5);

if(GETMONEY==0)
{
    int i = Money.textNumber+rand(100); // still uses textNumber in math operations
    Money.textNumber=i;
}

Yes, but if it's int then it rounds the number off, which means that it would round it to the nearest whole number before applying to the textNumber?

PS: I didn't realise the int could go inside a function on a normal script with GE, thank you! (I always define them at the top.)

Actually no. Setting it equal to an int will cast it (chops off floating point). To round to nearest whole number you should use round. But, my concern is that textNumber shouldn't be used as a variable, just as a way of displaying things.

Variables can be declared at the beginning of any code block. Notice how you can declare local variables in functions? Same idea. The variable will disappear after the code block is closed. For instance you can even declare it in a switch statement.

Code: Select all

switch(var)
{
    // start of a new code block
    int a;
    int b;
   
    default:
    // do something with a and b
    break;
}
