DivBlitz Opengl 2D Game LIb

[djoker]

Hi ppl this is my new lib with 1 simple game demo.

http://www.keepmyfile.com/download/8.../DivSpacer.rar



DirectInput : Mouse And KeyBoard,
DirectSound: Mp3,mod,s3m,wav,
Opengl :Blit functions;

procedure DivImage_Draw(Texture: PDivText;x,y,scaleX,ScaleY:single;angle:single;Col or:TColor4f;FBlendingMode:TBlendingMode);stdcall;e xternal 'DivBlitz.dll';

procedure DivImage_DrawRect(Texture: PDivText;Rect:Trect;x,y,scaleX,ScaleY:single;angle :single;Color:TColor4f;FBlendingMode:TBlendingMode );stdcall;external 'DivBlitz.dll';

procedure DivDraw_SubRect(Texture:
PDivText;x,y,SCallX,SCallY:single;SRect:TRECT;Colo r:TColor4f;FBlendingMode:TBlendingMode);stdcall;ex ternal 'DivBlitz.dll';

procedure DivDraw_SubRectTransform(Texture: PDivText;x,y:single;FlipV,FlipH:boolean;scaleX,Sca leY:single;CenterX, CenterY,angle:single;SRect:TRECT;Color:TColor4f;FB lendingMode:TBlendingMode);stdcall;external 'DivBlitz.dll';

procedure DivImage_DrawScroll(Texture: PDivText;R:Trect;UFactor,VFactor,ScrolXfactor,Scro lYFactor:single;x,y:single;Color:TColor4f;FBlendin gMode:TBlendingMode);stdcall;external 'DivBlitz.dll';

Particle class and Sprite Engine ...


is just 1 alpha release dont expect much...



ps:sorry 4 my bad english ops:

Can you try reupload the file, please, it seems that your file has been deleted or something...

[WILL]

I think I just fixed the link. Should work now. Was a simple matter of a wrong character.

Your engine's specs look promising and the screenshots look good too. Any future game projects in the near future with your engine? There has to be something in the works.


[size=10px]Just a few tips with posting code on PGD. If you are going to post code, please, please, please, use either the 'pascal' tags or the 'code' tags. It'll make your code snips stand out and are much easier to see and read.

Also, when posting code, especially INSIDE the code or pascal tags, don't put in space-less lines or it will make the page way too wide and hard for people to see and navigate. They'll focus more on the new size of their browser and not your message or code. :?

These small things will help make your posts more enjoyable for others. And less distracting. [/size]

[bigsofty]

The included example crashes for me.

EInvalidOp floating point exception, as soon as 1st wave of aliens come in form the left hand side.

[JC_]

For me works example OK.

But after compille this example in FPC 2.0.4 game crash after load screen -> something bad in procedure objectsEngine.Draw; (Procedure Update_Objects(time:single); )

Exist some new version of this lib ? Or smaller example with basic code (only one object..). Thanks.

btw. this units are missed - dxgutils,divvects,divgeo
