Hi everybody,
I’m trying to develop a jme3 car racing game
It’s a race viewer for a f1 browser game( f1project)
I’m trying to manage physics, but I have many problems with car impacts
Any suggestion from your experience to manage them ?

Thanks in advance

This is one problem, but the main one is that cars loose too much time when have accidents

Looks COOL

I’d try not modifying too many values at once. Reset all values to default and try what one value is doing. Another “trick” might be checking impact forces and applying opposing forces when the impact was too powerful.

I’ll try it
It could be a good idea

could you provide an example please?
PhysicsCollisionEvent gives me only float values of applied forces
How can I get a Vector3f force of impact?
Thanks

Theres the collision normal supplied.

Thanks for quick answer
Are getLateralFrictionDir1 and getLateralFrictionDir2 the right methods?

Dude, Very Cool! I love car games .

I need help on lights:
which could be the right combination of them to have a realistic effect?
My setupLightning method is very simple:

	public void setupLighting() {
        am=new AmbientLight();
        am.setColor(new ColorRGBA(1,1,1,.75f));
        rootNode.addLight(am);
        dl = new DirectionalLight();
        dl.setDirection(new Vector3f(-1, -1, -1f).normalizeLocal());
        dl.setColor(new ColorRGBA(1,1,1,.15f));
        rootNode.addLight(dl);
        dl2 = new DirectionalLight();
        dl2.setDirection(new Vector3f(-1, 1, 1f).normalizeLocal());
        dl2.setColor(new ColorRGBA(1,1,1,.15f));
        rootNode.addLight(dl2);
		}

where my shadow direction is the same of dl2 direction
any help would be appreciated
thanks
bye

Are you lightning the whole scene with only 3 lights?:o
Could be cool a ambient occlusion effect!

Don’t use the alpha portion on lights, I am pretty sure it does nothing. Instead scale the RGB values down
Also .. outdoor lighting generally has one powerful directional light (sun), which is usually light yellow, and low ambient lighting with the color light blue (sky). This will help you give a more realistic lighting model.

If its still not enough you can use normal mapping on some parts of the scene to improve the look

thanks, I’ll try and I’ll show you results
bye
