Java Game APIs & Engines / Java 2D / Gage Timer

on: 2003-08-08 05:09:05

Hellow,
I am using Gage Timer for my game loop, here is what i mean :

1
2
3
4
5
6

gameManager.update();
render();
sleep = gt.getTicksPerSecond()/60; //60fps
ticks = gt.getClockTicks();
gt.sleepUntil(sleep+ticks);
ticks = ticks+sleep;

The code shows i have a class "gameManager". Now if i wanted to create a new Timer (gmt) which is created "gameManager" for its indepedent events, will that timer be affected by the "gt" shown above ??

Basically, will the new timer run in a new Thread independent of gt or not ?
Thx

When i am drawing a lot of primitives, say 100 ovals, i get a lot of 8085 calls to sun.java2d.loops.Blit$GeneralMaskBlit and 8085 calls to sun.java2d.loops.MaskBlit and 992 calls to sun.awt.windows.D3DBlitLoops When i disable them 72 calls to sun.java2d.loops.MaskBlit and 72 calls to sun.java2d.loops.Blit$GeneralMaskBlit and 1783 calls to sun.awt.windows.D3DBlitLoops::Blit Arent primitives drawn with hardware acceleration ?

How does C# Compare to Jaba in terms of Performance ?

Quote I hope you aren't using System.currentMillis() for your bench. It's slow and has a very low resolution. So it cannot describe you the exact behavior of your program... Yes, i am afraid i am. I will change it to Gage or other high rez timer and post the results.

Quote 106415 calls to sun.java2d.loops.Blit$GeneralMaskBlit::Blit(IntArgb, SrcOverNoEa, "Integer RGB DirectDraw") 106415 calls to sun.java2d.loops.MaskBlit::MaskBlit(IntArgb, SrcOver, IntRgb) These are the things that kill your performance. This is a software blit of a translucent buffered image to an accelerated image (backbuffer). I see a couple of possibilites: - you have some sprites as bufferedImages for some reason (so they are not being accelerated) - you create more sprites that can fit in vram, some of them get accelerated, but most - don't - you render to your sprites more often than you copy from them Hey, i think the first possibility can be ruled out. Because on my every Image creation i am checking out whether they are accelerated after creation or not, and they all are. The second one might be true, since i am creating about 20 images to start with and create others on the fly (exlosions only). But apart from image i am creating other geometrical stuff all the time, about 100 geometrical things. Lets say i am creating about MAX 250 sprites. I dont think that is too much !! I have 32 Meg gfx card. One thing i think might be a problem is ur third possibility. I have put up a simple time bench on my updateEverything method and rendering method. This is what my console shows : Time Paint() - 15 Time Paint() - 15 Time Paint() - 31 Time Paint() - 15 Time Paint() - 16 Time Paint() - 16 Time Paint() - 16 Time Paint() - 15 Time Paint() - 15 Time Paint() -

15 And my threaded loop is like : gameManager.update(); gameManager.paint(bufferedGraphics); bufferedGraphics.show(); Thread.currentThread().yield(); ual.sleep(gameManager.REFRESH_RATE); What i am trying to show here is in my code i am trying to call my update() and paint() ONCE every refresh. But from my console i gather that my update method doesnt get called as often as my render(). Maybe because my sleep time is too short - like 10 millisecond. PS - Sorry for the long stupid looking post

Yeah max, but aplha acceleration is helpful when u are showing off ur snazzy (or even shabby) game effects. And u can set the aplha enabler in system properties anywayz !!

Since i am a "newless clubie" to the game scene, i dont know much.

Okae, my Images are Volatile and Accelerated !!! And i do see sun.awt.windows.D3DBlitLoops::Blit("Integer ARGB D3D with translucency", SrcOver, "Integer RGB DirectDraw") i was wondering that what effect does the Acceleration Threshold have on Rendering ?? And Thanks Abuse, for telling me that i have to set the properties before i init anything Graphical. No wonder my java -Dsun.java2d.trace=count wasnt working before. If java2D uses DirectDraw under the hood, why is it still so slow ? I heard that i can see a lot of performance difference if i switch to Lwjgl / jogl etc etc. ?

Hello ppl,
I am using this method and hoping i am getting Accelerated Images. Before using this method my images were automatic. I went from 30-40 Fps to 30-40Fps !!
Yes, no change ! So i was wondering if my images are accelerated and if i am really supposed to see noticible difference in performance.

I have enabled System Properties for Aplha Acceleration and forcing vram (which i suppose is to force images to be stored in vid ram). And also using Buffered Strategy.

When i create Colors with Aplha value, it gives me jerks / tiny halts. Same Happens when rendering those colors ! Isnt Transperancy in 2D Api supported in hardware ?

Here is the Code from the method that sets the Display Mode.

Umm. I also noticed that when i set Resolution higher than 1024 , say 1280 and 1600 ; My Frame Width query returns proper values. So its basically for resolutions below 1024x768 !!

Oh Btw Abuse, i am using Windows XP , 1.4.2 beta.

Hi, I have a stupid trouble with FullScreen mode. I am setting the Display Mode to 640x480xdesktopDepth. Now this just gives me an area of 640x480 while the rest of the area is left off as if i just wanted a 640x480 out of the 1024x768 (my Desk res). If i change to 800x600 then still it gives me a block of 800x600 from 1024x768 Rather than giving me larger pixel size. Lemme try making it a visual 1024 -> xxxxxxxxxxxxxxxBBBBBBBB\| xxxxxxxxxxxxxxxBBBBBBBB\| xxxxxxxxxxxxxxxBBBBBBBB\| xxxxxxxxxxxxxxxBBBBBBBB\| xxxxxxxxxxxxxxxBBBBBBBB\| xxxxxxxxxxxxxxxBBBBBBBB\| BBBBBBBBBBBBBBBBBBBBB\| BBBBBBBBBBBBBBBBBBBBB\| BBBBBBBBBBBBBBBBBBBBB\| x = Area delivered to me B = Background Color of my Frame Also when i query the Frame for height, it gives me 768 !! I am currently using 1.4.2 beta. Any clues ?
