Bugs / Geforce 4 and opengl
« on: October 29, 2005, 07:52:22 am »
Hi, I recently formated my PC, and I downloaded the most recent drivers for my MSI GForce 4 MX 440 Starforce and I notices that when rendering with opengl it takes almost 2 seconds for each thread iteration, it was awful, at first I thought that was my fault in the code, but when running the fps example it happened again.

I know that jpct offers opengl rendser using lwjgl, and I am not sure if you are able to fix this, but I may to tell that the most recent driver for all GForce and tnt cards are not well suported.

I dont know about GForce FX and Geforce 6 series.

Support / How to improve the textures!
« on: October 29, 2005, 07:32:46 am »
Hi, I used some textures I amde using 3ds max 6.0 and when using thwe opengl render they look fine, but when rendering by software it just a mess.

I know that software renders  with 24 bits per pixel on theur textures, but I tried to save them with less colors and I am having the same results.

It would be very nice to have a seccion with some free textures and models because the model I found on 3dcafe dont work and the textures I make are awfull when rendering.

Hey Egon, check this out:

Support / How to set a pivot point on the camera?
« on: October 22, 2005, 08:01:19 pm »
Well, the Subject says all. I want to set a pivot point to the camera, I want to move the camera on cirlces with the centrer placed on another place, like moving on the perimeter of a cirlce. How can I do that.

I have noticed that there are few new posts on the forums, so I wonder how much people is still using jpct?

Support / build only an specific Object
« on: October 05, 2005, 07:21:03 am »
Hi, I was making my game when I needed to add one more player, so I add the Object3D to the World, but I couldnt find a method to build it into the world, only the buildAllObjects () one. But If I build all the objects again I will lose time, resources and it will reset the pivot point of each Object3D ();

I am not sure but I remember that it was a build (Object3D method) inside the World class! What happened!

Feedback / suggestion

Hi, I have one sugestion about the engine.

Lights should have more functionality, like moving (translating), a radio maybe they should be able to be joined to an object3D, an aplication for that may be a laser or a misile shoot.

A weakness of this engine are the light efects.

Projects / Dissapointed
« on: September 20, 2005, 05:03:18 am »
Hi, I began writting my first 3d game, at the begining I was working well, but when I made enough of the game to have a small preview I was 100% dissapointed with it. It was awful so I decided to quit from this. I have not worked on it for almost 10 days. Today I want to try fixing it before throwing it to the trash can (virtually).

I began writting my code using the most common model of software development (code and fix ) :oops: .My 3D models were awfull, my textures didnt look as nice as I figured it out, the collision detection didnt worked well in this huge maps, the main menu seems to be made by a child :cry:

I want to know what knid of tecniques do you use to began with a project.

Do you really chose a model like the cascade one, then use a case tool like Rational Rose, and after all of that then you pay for getting good 3D models and finally codying it.

I always have used code and fix because I have kind of several brain storming while writting code, and it seems to be a bad idea.

Any sugestions?

Support / Some .3DS Files are not shown
« on: September 12, 2005, 07:10:00 am »
Hi, I download the jPCT API around Feb 2004, I dont know if this already have been corrected. Well I use 3d Studio Max to do my .3DS files, and I have noticed that Text is not only not shown but also make all the scene not to show when I Apply a bevel to it.

If I use the text as it is made just with lines it apperas a filled letter inside my game, but When I apply a bevel nothing appears when loading that scene.

Also When drawing straight lines they dont appear.

Support / Videos

Hi, I want to view videos, is there anyway to do that, I mean something like a FMV (full motion video) at the begining of the game!!!!

Support / Getting an object from a World
« on: September 10, 2005, 04:11:42 am »
Hi, am am doing a game in wixh I want to use two Worlds.

I wanted to have a methos that loads all the .3DS files from a given directorie so I have ordered my level in direcories like




and I just have to call a method to load all 3D objects inside, but as the my loading method loads Object in general, I used a local temporalObject3D, and after loading all inside the direcorie it builds them into the world with buildAllbjects ();

Now I need to move one of the .3DS files inside the directory I loaded, bus as I used a local object3D for generality reasons now I need to get the Object3D whose file is called Seleccionador.3DS but I cant, how can I do it, the file only have 2 pyramids but I need to move it, I tried using the getObjectByName (String name) from World but it didnt work.

Which are the names of the 3DS loaded, I tried using "Seleccionador", "Seleccionador.3DS", as it didnt worked I think can only the parts can be gotten with this method so I tried with "Pyramid01_jPCT18" because I saw that name when the 3DS file is being loaded, but it didnt worked too, how can I do that.

Support / Detecting OpneGL capability
« on: September 05, 2005, 09:29:11 am »
Hi, when I began trying this engine again, I tried to use the openGL but all what I got was a white screen, so I tried all what was possible, but I just couldnt, then I thought that it could be due to my graphic card, because I lend my GForce 4 to my brother and I was using my sis651 of 64MB that is supposed to have OpenGL compatibility.

When I bring my GForce again it worked perfectly, so I want to know if is there any way that the engine API can detect this capability!!!!!

Support / Using the mouse when using OpenGL
« on: September 04, 2005, 08:11:21 am »
Well, I have a pair of questions:

First is about using the openGL rendering, it opens a new Frame, how can I change the properties of that frame created when enabling the openGL render, for example, changing the title or things like that?

Second: KeyMapper is used to manage key events, but what about the mouse events?

Support / Whats wrong with my collision detection
« on: September 04, 2005, 03:24:53 am »
Hi, I have not used the engine in ages, so 2 days ago I began to do little project, but I just cant do the collision detection.

When I thought that it was good, I noticed that it didnt worked on the corners, I tried with other ways, but now the camera moves very quickly and no matter the speed I set.

here is my code for managing the events taken from the KeyState

Code: [Select]

public void movimientos () {
        boolean piso=false;
        try {
            if (Mundo.checkCameraCollision (new SimpleVector (0, 1, 0), alturaPersonal, alturaPersonal, false))

            if (adelante)
                if (Mundo.checkCameraCollision (camaraPersonal.getDirection (), alturaPersonal, alturaPersonal, true))
                    camaraPersonal.moveCamera (Camera.CAMERA_MOVEIN, velocidadPersonal);

            if (atras)
                if (Mundo.checkCameraCollision (camaraPersonal.getDirection (), alturaPersonal, alturaPersonal, true))
                    camaraPersonal.moveCamera (Camera.CAMERA_MOVEOUT, velocidadPersonal);
            if (izquierda) camaraPersonal.rotateAxis(camaraPersonal.getBack().getYAxis(), -0.02f);
            if (derecha) camaraPersonal.rotateAxis(camaraPersonal.getBack().getYAxis(), 0.02f);
            if (salto)
                if (Mundo.checkCameraCollision (Camera.CAMERA_MOVEUP, alturaPersonal, alturaPersonal*4/3, true))
                    camaraPersonal.moveCamera (Camera.CAMERA_MOVEUP, velocidadPersonal);
            if (agache) camaraPersonal.moveCamera (Camera.CAMERA_MOVEDOWN, velocidadPersonal/2);
            if (salida) System.exit (0);
        catch (Exception E) {

Well, the gravity done on the second line works good, the problem is when moving the camera to the front and back.

If I have to use another kind of collision detection please could someone explain me why and how?.

Somebody knows where can I download some free .3DS files, I am tired if doing own models, they are ugly.
