Support / two faces on the same plane!
« on: December 17, 2006, 11:16:38 am »
How can I solve this:

when two faces of objects are exactly at the same plane it generates a crossing texture showing efect or something like that. I mean that sometimes you se one, sometimes you see another, or mixed? can I fix this without remodeling the map making it appear just one of them.

Support / Merging optimize something?

Hello, I just want to know if merging objects improve the performance or resource asigment, or it just dont affect on anything?

Bugs / Exception and cant find the source
« on: November 06, 2006, 08:13:30 pm »
Hi, I tried to separate the rendering from the event handling but I have this Null pointer exception and cant find the source.

at null.null(Unknown Source)
   at Flier_Match.FMCliente.sistema.ManejadorEventos.ejecutarComandos( Compiled Code))
   at Code))

I tried putting some console mesasges but nothing seems to be null and the trace didnt show me any clue.

Support / Code for radar!
« on: November 01, 2006, 06:31:55 pm »
Hey Egon, is it okay if I use your radar implementation of the car demo on my game? I guess that I have lost all my math skills. BTW: Why dont you release a radar implementation on the next jpct release? that would be helpful! of course that the blit images, the scale, the plane must be parameters but anyway would be good.

Another question does your radar  show the relative position but on which plane are projected the plants over ZY or its relative to the car direction?

relative to car or relative to world.

My game FM recolects the events from the clients, passes them to the server, the server proces them, and return the state of all the clients to each client. now doing this means, 100% comunication with the server for each iteration, is this too bad?

Is this too heavy to do what I am doing?

    private SimpleVector posicion;
    private Direccion direccion;
    private int vida;//less tha 100
    private String nick;//less than 8 chars
    private int id;//one digit
    public NodoRed sig;//a reference
    public int cambio;//one digit

this are the fields that are being transmited from the server to the client.

I read somewhere that is not a good idea to do this for each iteration, maybe for one every 10 of them to keep a better performance, but I did on this way to avoid people cheating so, all the control is on the server.

Any suggestions? the game runs very very slow maybe 2 or 3 fps when the client is on a remote machine via LAN.

Support / Simultaneous Open AL sounds
« on: October 31, 2006, 07:32:56 pm »
Hi, I was checking the code examples provided on lwjgl and I made some modifications but I had problems when trying to play several sounds simultaneously. Like if only one sound could be played at a time!

Feedback / Software development

Hi, I asked something similar about 1 years ago, but just for curiosity, now that my project has died, I wonder why most of projects fails? In my case I found with some difficulties that couldnt solve on a easy way to integrate with the whole system. Any change would represent a major change on some places inside the code, I never definen a work plan nor made any ingeniering on it, just went to write code to do what I had on mind. But  sadly all my efforts on this project were useless and now, I just spent time on nothing. (Well I got experience).

I may want to ask, how to achive on a software project. Of course on the universitry I have received how to make RUP design, but I really cant find a real use of that. Actually I cant find a real way on which I cant really get help from the documentation for developing, maybe for making future changes but not by now.

I guess that everything have to be modular to can reuse the it on future version or future projects. But can I find a path to follow to avoid forgetting developing on a rigth way.

Egon told me once that he usese Xtreme Programming, but I guess I am using code and fix, and my project failed as supposed to be.

So, anyone can told advices about that? can Anyone here like Egon, Raft, Rolz, or anyother achieve on 3d projects? The succesfull projects have followed any kind of methodology?

Support / Rotating Blitted images
« on: July 09, 2006, 01:07:45 am »
Is it posible to rotate blitted images, I want to do a level meter (I dont know how to translate it). Anyway, I need to rotate a blited image, is ti posible or do I need to build the whole image by plotting small images.?

Support / Blitting a gif
« on: July 04, 2006, 06:38:09 pm »
Is it posible to blit gif animations instead of jpg images? I want to do it for a crosshair, that may be difficult to see when its over something of the same color, I want to do a crosshair as a gif animation in which the color change smottly so its easier to see.

BTW: I have problems blitting numbers, I made a 330 x 32 pixels contaning all the numbers from 0 to 9, but only the first one blits ok, I mean, the 0 appears ok, but the rest of numbers no, each number is at 33 pixels of width, but when trying to take the next 33 pixels it takes other things. I solved this testing with values and worked so so, asuming that the numbers are 23 pixels of width, but there arent.

Support / obj.lookAt ()
« on: June 21, 2006, 07:55:47 am »
Is there anyway to implement this method into the Object3D, it may be usefull, I need to make an object3D to look at (0, 0, 1), but I dont know its actual direction, of course I cant get the zAxis and calc a angle and the rotate it, but it will be kind of messy. If anyone have another idea, please post it. I have no another object to align with!

Support / Shoots!
« on: June 18, 2006, 04:37:24 am »
Hi, I am going to add some shoots to my game, so... How can I do it. I was thinking on having a preoaded 3d object with the bullet, and when a shot is done, it creates an element inside a list of automotion objects.

My idea is to have a motion objecto that means object3d inside the world that  have an auto movement like bullets or missiles, just giving them a init feature, defined movement and condition to exist, so they will be automatically removed when its done. I was thinking on having a list like this and a thread to move them while the game is running.

Any suggestion?
