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

[Andreaz]

Dont see why your strechdraw functions don't work, should only be as simple as this:

[pascal]
procedure TPHXImage.StrechDraw(X, Y, W, H: Integer);
begin
glPushAttrib(GL_ENABLE_BIT or GL_COLOR_BUFFER_BIT or GL_CURRENT_BIT );
glEnable (GL_TEXTURE_2D);
glEnable (GL_BLEND);
glDisable (GL_DEPTH_TEST);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glBindTexture(GL_TEXTURE_2D, FTexture);

glPushMatrix();
glScalef(W / Width, H / Height, 1);
glTranslated(X,Y,0);
glCallList(FDisplayList);
glPopMatrix();


glPopAttrib();
end;

procedure TPHXImage.StrechDraw(X, Y, W, H: Integer; PatternIndex: Cardinal);
begin
glPushAttrib(GL_ENABLE_BIT or GL_COLOR_BUFFER_BIT or GL_CURRENT_BIT );
glEnable (GL_TEXTURE_2D);
glEnable (GL_BLEND);
glDisable (GL_DEPTH_TEST);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glBindTexture(GL_TEXTURE_2D, FTexture);

glPushMatrix();
glScalef(W / PatternWidth, H / PatternHeight, 1);
glTranslated(X,Y,0);
glCallList(FDisplayList+PatternIndex+1);
glPopMatrix();


glPopAttrib();
end;
[/pascal]

And yeah, custom frame support would be good, probably just need to look something like this ?

[pascal]
TPHXFrame = class
DisplayList: glUint;
Image : TPHXImage
PatternX : Integer;
PatternY: Integer
PatternWidth : Integer;
PatternHeight: Integer
end
[/pascal]

And btw, dont mess with the DisplayList property of the image class, you will break alot of code if you do so

Nice to hear about the tuts

The stretch draw is working fine now. Rotate still has some problems - I dont think its really rotating properly.

I have made all the changes I wanted onto the phxImage class.

I started trying to make a small game last night. I could not get FullScreen working properly - are there any issues with it?

Sounds good !

There's no fullscreen issues that i'm aware of, just set fullscreen to true in the window constructor.

A few days late but here's the latest release:

http://www.glxtreem.net/Phoenix2006-08-03.rar

The sprite engine is included, as well as a early version of the sound engine, no need to initialize OpenGL yourself anymore and setOrthoMode is done by default. And some fixes and tweaks as usuall!

Well, as you can see from the front page, I finally got the importer working properly. Once I get Indexed Property code generation working I'm going to start wraping up all of the classes in the game and engine. Once thats complete full scripting support should be availalble.

I have ran the wrapper generator on everything thus far, and with the exception of the indexed properties, everything generated properly. Also have to fix Records, but those don't seem to be in use right now .

I can even wrap the OpenGL calls so that you can make use of them inside of the scripts

Cool! nice work chief!

Especially the OpenGL calls bit

cheers,

Why does it automatically set VSync on?

Do you want the image drawing functions I've done - I notice they are not included.

I am starting to work on my tutorial set - can we have a release 1 sometime soon. My deadline is actually friday. In addition I want to start using this for a project of mine - I need some stability.

I have started creating a state manager. Needs a bit more work - making it more extendible - will release soon.

Because i noticed some screen flickering with vsync off, so i opted for having it on by default

Do you want the image drawing functions I've done - I notice they are not included.

Maybe you also noticed that you sent me the file after the last release I gonna include it with some modifications, for example speeding up the tiledraw and such. Need to fix the state changes as we discussed before aswell (ie no glColor4f( 1.0, 1.0, 1.0, 1.0).

A release 1 wont make it more stable But if you experience stability problems we just have to fix em, simple as that I have caught a nasty cold so it will probably not be that much coding done over the next few days.

[cairnswm]

A release 1 wont make it more stable

But it will fix the unit and class names Each version so far has had unit name chnage - and class name changes.

I just want something to start working with

Wow, this project is coming along quite a bit, no?

How many people have been working on it and/or contributing?

[jdarling]

Well, I've been working on it, but haven't yet put my stuff up as a contribution due to issues that are almost completely resolved. Soon, very soon, my precious... Err... Soon, the scripting wrappers will be complete. I have a running version now that lets you create, load, and display all just fine. Overloaded methods and events arn't working (and it will be quite some time till the events work) but other then that I'm just awaiting the next build so I can make sure that the wrappers all still work. If they do, I'll post them to be included in the package.
