Hello

What would be a good technique to create a dirt smoke effect for a car running off-road?

Thank you

Particle effects!

getting them to trigger when you are “offroad” pretty much depends on how the rest of your game works…

Thanks Joe

We have been learning the particle system by trial and error, but so far we have not been able to get good results.

Particles are a tricky beast and largely come down to personal taste and tweaking when one tries to implement them. Some values I’d look at are sizeGrow field in ParticleAnimator (larger values will make the particles grow as they linger, creating the “Roadrunner” dust cloud effect), adding a slight upward force in the ParticleAnimator, and setting the localVelocity.z by scripting to the negative z-velocity of whatever is triggering the effect. There is a great particle tutorial Yoggy did (that I found via the wiki: http://forestjohnson.blogspot.com/2007/12/particle-effects-tutorial.html. You can start at Ch.1, step 4 if you’re not interested in creating your own particle textures.
