Hey, I need to randomize 30 numbers into an Array, each number is a randomized number between the int limits (both negative and positive)
Although, my code doesn't work, and on second thought it's not even logic.
Anyone ?

PHP код:

#include <a_samp>
new Array[30] = {0, ...};
main()
{
    // Setting variables
    for(new i = 0, j = sizeof(Array); i < j; i++) Array[i] = random(0x7FFFFFFF) + (-0x7FFFFFFF), printf("%d", Array[i]);
}

By 'doesn't work' you mean it doesn't give the desired result?

Well, all you really need to randomise is the difference between the two amounts. So lets say I want a value between -24 and +15. The difference between the two numbers is 24 + 15 = 39. So:

PHP код:

random(40) + -24 


PHP код:

new Array[30] = {0, ...}; 
main() 
{ 
    // Setting variables 
    for(new i = 0; i < sizeof(Array); i++) Array[i] = random((maxvalue - minvalue) + 1) + minvalue, printf("%d", Array[i]); 
} 


Also, sizeof is not a function. Think of it as a macro. It gets determined upon compilation.

Still all values are negative, maybe the variable type of random() is int ? (so maxvalue - minvalue is too high))

What are you using for maxvalue and minvalue?

Well obviously using the maximum value for a 32-bit integer and having it doubled is going to cause issues. Use smaller values.

0x7FFFFFFF - (-0x7FFFFFFF) = 0x7FFFFFFF + 0x7FFFFFFF = 2 * 0x7FFFFFFF

You can't go above 0x7FFFFFFF :>

K, thanks
