Getting string data from integer variable

[Troodon]

Hi,
How can I get string data from a number variable?
For example, I want to analyze from a number (for example 2047):

if (first number == 2)
{
something happens
}

etc etc

If the number is an integer, use:

Code: Select all

sprintf(text, "%d", number);

if(text[0] == '2')
{
  ...
}

[Troodon]

Thanks! I will try this as soon as I get home!

[Troodon]

Uhm, I entered

Code: Select all

sprintf(text, "%d", numero);

if(text[0] == '2')
{
  CreateActor("numero", "icon", "no parent", "no path", rand(10), rand(10), false);
}


And it says:
Errror line 1: passing a struct/union to variadic function "sprintf"

Where do I put the actor name and what's the input number place?

[makslane]

Double check the code. Works here.

[DilloDude]

The input number is the number in the first line. It should be

Code: Select all

sprintf(text, "%d", your_input_number);
...

Also, if you don't want to display the number as 'text', you can create another temporary variable:

Code: Select all

char temp[10];
sprintf(temp, "%d"...
if (temp[0] == '2')
...

[Troodon]

It gave me another error message but only when I go to demo mode:

Code: Select all

luku -> key down (a, Atleast one key is pressed), line 4: READ attempted beyond allowed access area

The line 4 is:

Code: Select all

if(text[0] == '2')

Sorry, use an other string var instead.

[Game A Gogo]

The var "text" is already a var, it is the text of an actor, like the textNumber is the number of an actor.

Try using Text instead.

[Troodon]

Now it says:
Suspicious pointer conversion
Must have pointer

This is my current code:

Code: Select all

numero = rand(1000);

sprintf(Text, "%d", numero);

if(Text[0] == '2')
{
  CreateActor("tuloste", "shot", "no parent", "no path", rand(100), rand(100), false);
}

[DilloDude]

You'll need to define Text before you use it, at the beginning of the script:

Code: Select all

char Text[20];

The number should be the maximum number of characters you'll want plus one (because the string must end in a null terminator).

[Troodon]

Fantastic! It works!

I will ask you still one question, then I will let you in peace

Is it possible to create that integer with a way something like this:

Text[0] = 'rand(9)'
Text[1] = 'rand(9)'
Text[2] = 'rand(2)'
etc etc

If it's not possible, nevermind.
I know I could do this easier with many variables instead of one but my project has too many variables to be displayed in the script window. In my project this will be used like a gene. Little difficult to explain but it should be in one integer variable to work.

you can make an array and Access points of the array.
(one variable to access 1000's or more functions)

[makslane]

Use:

Code: Select all

Text[0] = rand(9) + '0';
Text[1] = rand(9) + '0';

All C strings must end with a NULL char. So, in the last position put:

Code: Select all

Text[last pos] = 0;

Thanks.

By the way, Sparky talked something about arrays. What are they? Can they be saved like normal variables?
