Tutorial: Hello World In GML

The source code

Code:

// Hello World In GML

show_message("Hello World!");
keyboard_wait();
game_end();

What does it all do?

Code:

// Hello World In GML

This is a comment - it doesn't get executed.

Code:

show_message("Hello World!");

This function creates a pop-up box with the text inside the string. show_message() is known as a function.

Code:

keyboard_wait();

A function which makes the program wait until the user presses any key before it goes onto the next instruction.

Code:

game_end();

Does exactly what it says - ends the game. In other words, terminates the program.

How do I compile it?

To use GML, you need to download Game Maker - the lite version is free. When you have installed it, just create a room, and put the source code in the room creation code (under "settings").
