Writing a better 2D engine. (Phoenix 2D Game Engine)

[Andreaz]

Time for a small status update

I have got the basics of the sprite engine working, some work left on optimizations and colissions through. I have converted the basic parts of the GLXTreem gui engine aswell and it works nice.

One pending project atm is the font compiler, it should really need some more work (support for symmetrical grid fonts for instance, maybe nehe's font format (yes the font renderer will cope with that quite easilly ) ) If someone feels like ending up on the credit list the source for the font compiler is included in the last release.

Andreaz, can you post up the DL link again. I'd like to make sure that the wrapper stuff is still on target and wrap up the things that you have added. As well as integrate the XML stuff I finally completed.

Shure, here's the latest soruce:

Oh, and there's already a xml parser included (written by myself and is a modified version of the one used in GLXTreem) that the component engine uses.

Hi...

A suggestion, about the Particle Engine, you could give a look o XParticles for Asphyre. It´s a very good particle engine with editor already ready, and i think it will be not hard to convert. I think the author will allow the conversion if asked.

Hi Andreaz...

I can´t compile the Sprite Example. It´s missing the phxSpriteEngine.pas file.

Seems i forgot to add that one to the rar file, you can get it from here:

I just figured that it wasn't complete yet

Quite correct, yesterday i've reworked the collision groubs a bit so now you have very goood control on wich sprites can collide with eachoter (by making smart seperations you can get very good speeds with no fancy optimisations). I also extended the animated sprite class so it really supports animated sprites. Still some work on the collision detection and responce left.

Yet another status update:

The sprite engine is now working very good, currently working on wrapping up a small demo showing off some of the functionality, there will be a much larger demo/game aswell but i'll leave that as a surprise.

Have started writing a SoundEngine using OpenAL aswell and it's progressing well, nothing fancy yet.

Cairn, hows the image list going, i came up with a nice idea to improve the pattern animaton, to add 2 new variables: PatternSkipX and patternSkipY, wich does just as it sounds, skips a few pixels for each pattern, could be usefull for nonpower of two textures and the gui engine for instance.

Gonna try getting a new version up tonight

Edit: And btw, if there's anything you feel that could be improved or is working badly dont be afraid to say so. Feedback is much welcome !

A status update from me

I started adding the other Pattern based drawing functions last night. Unfortunatly it doesn;t worked with scaled images. I am still busy making the changes.

I want to add methods to allow custom patterns to be defined (ie define sections of the image as new sprites that then use the normal drawing functions) - however this wont then work with the stretch draw functions.

I am starting a set of articles for a local free game dev magazine (Gameforce - http://gamedev.co.za) on making 2D game with FreePascal and Phoenix. I will include all the aricles I write for inclusion in the Phoenix download. (It will be a 6 part series).
