GML Problem with objects/instances

[RisingKane]

Hi there!

I'm trying to continue making my game, but I'm facing some objects/instances problems. I'm working on the code (script) below:

with (obj_button) {

    if (empty) {
        show_message("EMPTY");
    }
    else {
        for (i = 0; i <= array_length_1d(vec_exe) - 1; i += 1){
            show_message(vec_exe[i]);
        }
    }
}

But the tricky part is that I have 4 instances of "obj_button" on screen when the game starts, so the messages are shown 4 times, but I want them to be shown only once. Does anyone know how to fix that?

Thanks!

You can do:

var message;

with (obj_button) {

    if (empty) {
        message = "EMPTY";
    }
    else {
        for (i = 0; i <= array_length_1d(vec_exe) - 1; i += 1){
            message = vec_exe[i];
        }
    }
}

show_message(message);

            message = vec_exe[i];
        }
    }
}

show_message(message);

Thanks for your answer, NazGhuL!

I understood what you said, but the problem is that, in that code, the 'message' variable will contain only the last position of the 'vec_exe' array. I'd like it to have all the positions. I'm trying that by using another for, outside of the 'with(obj_button)' clause, I'll have some results soon. Thanks again!

You want to display all message?
Like:

var message;

with (obj_button) {

   if (empty) {
       message += "EMPTY#";
   }
   else {
       for (i = 0; i <= array_length_1d(vec_exe) - 1; i += 1){
           message += string(vec_exe[i])+"#");
       }
   }
}

show_message(message);

       }
   }
}

show_message(message);

Yeah dude, that worked out! The thing is that, at least I think so, as 'obj_button' had 4 instances on screen, the game displayed one message for each instance, thus, the same message was shown 4 times, in the same message box. It was something like this:



All I did was writing that code you made inside another object that had only one instance on screen, like this:

var message;

with (obj_another) {

   if (empty) {
       message += "EMPTY#";
   }
   else {
       for (i = 0; i <= array_length_1d(vec_exe) - 1; i += 1){
           message += string(vec_exe[i])+"#");
       }
   }
}

show_message(message);

Then, I got what I wanted:



Thanks again!
