 `mask` is a number between `0x0000` and `0xFFFF` and used as a bitfield, which means you can combine these flags with `bor`. These are the available flags (excerpt):
 
-|| *Flag* || *Collision with …* ||
-|| `0xFF00` || Terrain ||
-|| `0x0080` || Current hedgehog and crates ||
-|| `0x000F` || Other hedgehogs ||
-|| `0x0070` || Mines and explosives ||
+|| *Idntifier* || *Collision with …* ||
+|| `lfLandMask` || Terrain ||
+|| `lfCurrentHog` || Current hedgehog and crates ||
+|| `lfHHMask` || Hedgehogs except current hedgehog ||
+|| `lfNotHHObjMask` || `not lfNotHHObjMask` ||
+|| `lfAllObjMask` || Mines and explosives ||
 
 Beware, the collision mask is often set by the engine as well.
 
 Examples:
-<code language="lua">SetGearCollisionMask(gear, 0xFF7F)
+<code language="lua">SetGearCollisionMask(gear, bnot(lfCurrentHegehog))
 -- Ignore collision with current hedgehog</code>
 
 <code language="lua">SetGearCollisionMask(gear, 0xFFFF)
 -- Collide with everything</code>
 
-<code language="lua">SetGearCollisionMask(gear, 0x00FF)
+<code language="lua">SetGearCollisionMask(gear, bor(bor(lfHHMask, lfCurrentHog), lfAllObjMask))
 -- Collide with hedgehogs and objects</code>
