Question

My question is, which one is better to use? How to properly use a switch statement. Should I use variables or not etc. I thank you in advance for your reply. “random text because I need a lot of explanation or else it won’t let me post.”

switch(level_id)
{
    case 1:
        stage.addChild(new lvl(50, 200, 100, level_id));
        break;
    case 2:
        stage.addChild(new lvl(50, 200, 100, level_id));
        break;
    case 3:
        stage.addChild(new lvl(50, 200, 100, level_id));
        break;
    case 4:
        stage.addChild(new lvl(50, 200, 100, level_id));
        break;
    case 5:
        stage.addChild(new lvl(50, 200, 100, level_id));
        break;
    case 6:
        stage.addChild(new lvl(50, 200, 100, level_id));
        break;
    case 7:
        stage.addChild(new lvl(50, 200, 100, level_id));
        break;
    default:
        break;
}

or

switch(level_id)
{
    case 1:
        x = 50; y = 200; x = 100;
        break;
    case 2:
        x = 50; y = 200; x = 100;
        break;
    case 3:
        x = 50; y = 200; x = 100;
        break;
    case 4:
        x = 50; y = 200; x = 100;
        break;
    case 5:
        x = 50; y = 200; x = 100;
        break;
    case 6:
        x = 50; y = 200; x = 100;
        break;
    case 7:
        x = 50; y = 200; x = 100;
        break;
    default:
        break;
}
stage.addChild(new lvl(x, y, z, level_id));

What I finally did (edit)

Final result, thanks all

var config:Object = {
               "1":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 },
               "2":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 },
               "3":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 },
               "4":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 },
               "5":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 },
               "6":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 },
               "7":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 },
               "8":{ "paddWidth":50, "blockWidth":200, "blockHeight":100 }
            };

            stage.addChild(new lvl( 
                        config[level_id].paddWidth,
                        config[level_id].blockWidth,
                        config[level_id].blockHeight,
                        level_id
                        ));

Answer 1

Another option might be (untested code):

var config:Object = {
   "1":{ "x":50, "y":100, "z":150 },
   "2":{ "x":51, "y":101, "z":151 },
   "3":{ "x":52, "y":102, "z":152 },
   "4":{ "x":53, "y":103, "z":153 },
   "5":{ "x":54, "y":104, "z":154 },
   "6":{ "x":55, "y":105, "z":155 },
   "7":{ "x":56, "y":106, "z":156 },
   "8":{ "x":57, "y":107, "z":157 }
};
x = config[level_id].x;
y = config[level_id].y;
z = config[level_id].z;
stage.addChild(new lvl(x, y, z));
