Our new script, which we'll call "drawTextCentered", will take four arguments: (1) the string of text, or simply string, that we want to write out, (2) the x-position of the drawing area, (3) the y-position of the drawing area, (4) the width of each character, and (5) the width of the area in which we want to center the text. The arguments are named argument0, argument1, etc. In that case, the value will default to zero. Scripts always take in something like 5-6 arguments, although you don't have to use all of them. A parameter defines what the function accepts, and an argument is like the actual value you end up feeding it. Using a vending machine as an analogy, "coins" would be the parameter, and if you put in a quarter, that's the argument. the words "parameter" and "argument" are used somewhat interchangeably by lazy computer scientists, but they're actually different. StrLen = string_length(str) * widthOfChar Give the arguments more descriptive names Draws text centered within a certain area Inside the Create Event for oInit, let's define our sprite font (we'll call it myFont) like this: If you'll recall, variables have scope that determines how far they exist. Since we'll be using sFont throughout the entire game, let's make it a global variable.
oTitle will handle everything that happens on the title screen. We won't have very much to initialize to begin with, but when your games get more complex, an object like this might become very useful. oInit will be where we'll initialize the game. Make a room called rTitle and put two new objects in it, oInit and oTitle. Let's create a title screen to test our new font in.

Mario, Megaman, and PC Bios characters! I got my characters from here. So if you want to include numbers AND capital letters, like we are going to want in this tutorial, you'll need to include the 7 characters in between them - ": " - or at least 7 frames representing them.Īnd this is our sprite, sFont, that includes numbers and capital letters: The ordering, however, is important - it follows ASCII, and you can't skip any characters. If you only need numbers, for example, you can just include those. You can use as many or as few of the characters as you need. Each of the frames of the sprite will be a different character of the font. To make a sprite font, first create a new sprite.

This will make our code much easier to read and write.

We're also going to learn how to write scripts for commonly-used or important code. It may take a little longer to implement one (especially if you're drawing your own from scratch), but the results are well worth it. Fortunately, Game Maker supports sprite fonts. You also run the risk that the player doesn't have the font installed on their computer or their computer renders the font slightly differently. You can easily use Arial, Courier, Helvetica, Verdana, or some other standard system font, but it looks cheeseball and people will notice. Unfortunately, as a game developer you can spend a lot of time working on them. The player might not spend much time thinking about them when they're done well, but they stick out like a sore thumb when they're done lazily. these are really important aspects of a game. Okay, text boxes, menus, user interfaces.
This time, we're dealing with some REALLY interesting stuff. Last time, we made the screen scroll and added stars to the background and other boring junk like that. We're also going to learn about scripts, which are player-created functions. In this fourth part, we're going to add a simple title screen with some text on it and add a HUD to the game. Suitable for programming nubs, also.Ībstract: We're making a simple, one-level side-scrolling shoot 'em up using Game Maker and GML. Level: Total newb to Game Maker (that has read the previous tutorials).
