How do you draw random numbers?

[mrdude317]

I got game editor recently, and tried to make a simple program that when the spacebar is pressed, a random number appears (like a virtual dice). I put in the action "Script Edit", and put in this:

strcpy(aaa.text, rand(6));

when I try to click 'ok', it comes up with this error:

"Error Line 1: Incompatible types: cannot convert from 'double' to '* const char' "

What am I doing wrong?

instead of

Code: Select all

strcpy(aaa.text, rand(6));

, use this

Code: Select all

aaa.textNumber=rand(6);

You can't use a string function to copy integers.
Use

Code: Select all

textNumber=round(rand(5)+1);

This will get you a round number from 1-6.

You beat me to it Game a Gogo

lol, its ok but if you don't want to include a zero use something similar to Novice:

Code: Select all

aaa.textNumber=rand(5)+1);

You could use a string function if you wanted...

Code: Select all


sprintf(aaa.text, "%f", rand(6));



and its got benefits, like easily being able to format the number to n decimal places if it is floating-point.

Code: Select all


sprintf(aaa.text, "%.0f", rand(6)); // 0 decimal places


sprintf(aaa.text, "%.2f", rand(6)); // 2 decimal places
