Welcome to this humble tutorial. The ultimate goal of these chapters will be to create a fully working arcade game emulation coded entirely in Blitzmax. It’s not written as a BlitzBasic → BlitzMax tutorial. My aim is to give anyone the opportunity to get a good start in learning the fantastic BlitzMax. This is the start of a fairly ambitious series of tutorials on how to write 2D games using BlitzMax. The first part is a Getting Started part where I’ll be introducing.

The second part will walk hutorial through how to create a framework of a 2D game and will use a very simple space shooter as an example. You can find related info here: It might happen during this tutorial that I mix the usage of type and class as they are identical and class is the more often used phrase to me ;- What is a Type now?

Assari, Are you planning on writing a book for your tutorials and knowlege?

So the interesting part is the modified main loop. The caller does not know if the logicFPS is calculated for each call or precalculated on instance creation time. If you don’t manage to figure that out on your own you shouldn’t yet consider coding your own games.

All code between those keywords belongs to the type. The Update method is not very complicated to understand. After all enemies of a phase have been destroyed the next phase starts with more enemies, harder enemies, faster enemies and so on.


The beginning Chapter 2: We now got a working code base. What tugorial do here is calling the update methods with a given fixed rate all the time, for example every 20 milliseconds. The accumulator is increased by the delta value so that the accumulator always contains the milliseconds since the last completed update call.

We start with some field declarations. If dssOn is true we store the current delta value in the dssArray and immediately calculate the smoothed delta. I am a nlitzmax to BMax and must congratulate you on such a good piece of work your tutorial is.

I’ve just added a new part to the basic framework series: And if you have two or more objects of type TXYZ all of those objects have their unique values inside the fields, just like uttorial can have a red car with three doors and a blue car with five doors.

This project wouldn’t exist without his help. First we switch on “SuperStrict” as I already recommended. By Gnollrunner Started December You’ll have to do that on your own, for example in the Create function of your type.

BlitzMax IDE(BASIC) Vs. C , which is better for beginners? – Forum –

I’ll buy it if you do: The Type declaration line ends with the keyword Abstract which tells BlitzMax two things:. If a type is abstract you cannot create instances of that type. It is a ‘Basic’ language that incorporates advanced 2D graphics capabilities along with sound, input, etc.


Because different computers have different speeds older ones are generally slower than the newest high end quad core machines this main loop would run at different speeds too. But first we define a global Global playerImg: TCoordinate or Where am I?

Float which will contain all required calls to update and render the game objects. The tutorial is a work in progress right now and only blitzmaz thoughts and reminders about how to proceed. I would probably say that no, learning the C languages would most likely NOT be better.

So we can compare against it.

Float and Render tween: It will be properly written over the next few weeks or months ;- Part bitzmax of the tutorial. Each drawing or rendering phase will move your game elements closer to their new position that was calculated in the update phase.

I don’t really like the C-syntax, so I’ll be better quiet. There are two methods SetPosition x: That means we need to implement the Update and Render methods later on in our type. It returns true if enough time passed to at least call the update routines of the game elements once.
