Is there a way to hitTestObject Particles?

Hi Macco If you use a DisplayObjectRenderer then each particle is represented by a unique display object and you can do a hitTestObject on it. The display object is the particle's image property ...

If you use a DisplayObjectRenderer then each particle is represented by a unique display object and you can do a hitTestObject on it. The display object is the particle's image property so do

displayObj.hitTestObject( particle.image );

If you use a PixelRenderer then each particle is represented by a single pixel and you can do a hitTestPoint on the particle's x and y position

displayObj.hitTestPoint( particle.x, particle.y );

If you use a BitmapRenderer then you can't do a hitTestObject on the particle. In theory you could create your own hitTest method based on the particle's x and y coordinates, scale, image.width, image.height, etc.]]> http://flintparticles.org/forum/comments.php?DiscussionID=64&Focus=1250#Comment_1250 2010-07-16T19:08:11+01:00 2011-12-11T11:28:15+00:00 Ubuntu http://flintparticles.org/forum/account.php?u=387

I am very confused with the particle hitTestObject and hitTestPoint because I cant find any examples and cant get mine to work. I am using your GravityWells class except the emitter is called ...

if(Testbox.hitTestPoint(gravityemitter.particles.x, gravityemitter.particles.y))
{
trace('hit');
}

What am I doing wrong? btw for the displayobjectrenderer and pixelrenderer is there anything that must be imported for the hitTests to work? And are there any online examples? Other than this, I love your Particle Engine Richard, and I am planning on creating some games with them. -Thank You]]> http://flintparticles.org/forum/comments.php?DiscussionID=64&Focus=1258#Comment_1258 2010-07-24T17:41:44+01:00 2011-12-11T11:28:15+00:00 Richard http://flintparticles.org/forum/account.php?u=1
