Bullet object passing through other dynamic objects

[OzLark]

In my game if I fire my projectile fast enough, it may pass through or even embed its self into other dynamic or static objects..

What's going on? If I slow the projectile down it behaves okay, but fast and weird stuff starts!

Any ideas?

See my post at the link below. Adjust the last two digits until you've achieved the behavior you desire.

Taken from the Box2D Manual:

Fast moving objects in Box2D can be labeled as bullets. Bullets will perform CCD with both static and
dynamic bodies. You should decide what bodies should be bullets based on your game design. If you
decide a body should be treated as a bullet, use the following setting.

bodyDef.bullet = true;

The bullet flag only affects dynamic bodies.
Box2D performs continuous collision sequentially, so bullets may miss fast moving bodies.

Thanks for your replies,

My problem was caused by:

this.mPhysicsWorld.setContinuousPhysics(false);

Removed this call and all seems fine again!

I already had the body set as a bullet, so I was somewhat stumped.

Cheers.
