Ultra GL - The open source Wipeout clone!

WIP games, tools & toy projects Archived Projects
#1

Ultra GL is going to be a fast, cross platform Wipeout clone that focuses on the arcade feel, and tight controls that make Wipeout so great!

I’ve already managed to get a basic engine going, with lighting, sounds, music, input, textures, and collision detection.

I’m looking for a few good men to help out with this project. It’ll be completely open sourced from start to finish.

Wanna know more about what I’m talking about?

Here’s a video of it so far.

And here’s a tech demo:

Here is the source code: http://prime.programming-designs.com/java/ultra_gl/ultra_gl_dec_28_09.zip

I managed to fix the error where if you have a road with -depth the car wouldn’t go down by changing the code in void coltest(Ship a) to:


if(groundTest[i].depth > 0.0f)
                    a.rotx = (float) (Math.atan(groundTest[i].y/groundTest[i].height) * ((360/2)/3.14159265));
                
                else if(groundTest[i].depth < 0.0f)
                    a.rotx = (float) -(Math.atan(groundTest[i].y/groundTest[i].height) * ((360/2)/3.14159265));

                
                else
                    a.rotx = 0;

Now I just need to fix the collision to not stop making the car go up/down once the car’s maxz goes off the road onto another.


if(a.minx < (groundTest[i].x + groundTest[i].width) &&
            a.maxx > groundTest[i].x && a.minz < groundTest[i].z &&
            a.maxz > (groundTest[i].z - groundTest[i].height)) // end of error
            {

Since I’ve been asked to I’ll post the whole method’s code with comments


 void coltest(Ship a)
    {
        boolean b = false;
        
        //loop * number of roads
        for(int i = 0; i < maxGround; i++)
        {
            //if you're inside the current road
        	//here is the slowly get pulled under the track error...
            if(a.minx < (groundTest[i].x + groundTest[i].width) &&
            a.maxx > groundTest[i].x && a.minz < groundTest[i].z &&
            a.maxz > (groundTest[i].z - groundTest[i].height)) // end of error
            {
                //set current road to i
                a.cur_col_face = i;

                 //if road depth > 0 make the car rotate up
                if(groundTest[i].depth > 0.0f)
                    a.rotx = (float) (Math.atan(groundTest[i].y/groundTest[i].height) * ((360/2)/3.14159265));
                
                //if road depth < 0 make the car rotate down
                else if(groundTest[i].depth < 0.0f)
                    a.rotx = (float) -(Math.atan(groundTest[i].y/groundTest[i].height) * ((360/2)/3.14159265));

                
                else
                    a.rotx = 0;



                b = true;
            }
        }

        if(!b) // if outside of road reset car position.
        {
            a.x = -5;
			a.z = 10;
			a.y = 2;
        }
    }

Lighting


private float lightAmbient[] = { 0.0f, 0.0f, 0.0f, 1.0f };  // Ambient Light Values ( NEW )
    private float lightDiffuse[] = { 1.0f, 1.0f, 1.0f, 1.0f };      // Diffuse Light Values ( NEW )
    private float lightPosition[] = { 0.0f, 0.0f, -5.0f, 1.0f }; // Light Position ( NEW )
    private float lightSpecular[] = { 1.0f, 1.0f, 1.0f, 1.0f };



ByteBuffer temp = ByteBuffer.allocateDirect(16);
        temp.order(ByteOrder.nativeOrder());
        GL11.glLight(GL11.GL_LIGHT1, GL11.GL_AMBIENT, (FloatBuffer)temp.asFloatBuffer().put(lightAmbient).flip());              // Setup The Ambient Light
        GL11.glLight(GL11.GL_LIGHT1, GL11.GL_DIFFUSE, (FloatBuffer)temp.asFloatBuffer().put(lightDiffuse).flip());              // Setup The Diffuse Light
        GL11.glLight(GL11.GL_LIGHT1, GL11.GL_POSITION,(FloatBuffer)temp.asFloatBuffer().put(lightPosition).flip());         // Position The Light  
        GL11.glLight(GL11.GL_LIGHT1, GL11.GL_SPECULAR,(FloatBuffer)temp.asFloatBuffer().put(lightSpecular).flip());         // Position The Light  
        
        GL11.glEnable(GL11.GL_LIGHTING);
        GL11.glEnable(GL11.GL_LIGHT1);
        
        //GL11.glEnable(GL11.GL_COLOR_MATERIAL);
        GL11.glShadeModel(GL11.GL_SMOOTH);

        //float global_ambient[] = { 0.5f, 0.5f, 0.5f, 1.0f };
        //GL11.glLightModeli(GL11.GL_LIGHT_MODEL_AMBIENT, 0xff0000ff);

        
        GL11.glMateriali(GL11.GL_FRONT_AND_BACK, GL11.GL_SPECULAR, 0xffffffff);

Sorry I get this:

I got an error, something about a memory error.

EDIT: it worked fine though, this error was on close.

#7

Hmmm… no luck for me too ;D

Works for me,… but it’s very far from a wipeout clone.

I used to love Wipeout 2097.

what are you planning to do for collisions? and map creation? (I mean in the long run)

I actually wouldnt mind helping with this project as so far its LWJGL.

check out this link:
http://www.psionic3d.co.uk/?page_id=25
it has a free wipeout like ship model, that would work great as a placeholder. The “fighter.zip” model.
