== Overview of differences between COB unit scripts and Lua unit scripts ==

* Units of measurement: Lua uses elmos and radians consistently.
* Coordinate system: In Lua, coordinate system is same as world coordinate system, with all rotations right-handed. In COB, the moves along the x-axis and rotations around the z-axis have a different sign.
* In Lua, ''Killed'' gets recentDamage and maxHealth as separate arguments. In COB, you get only the ratio recentDamage/maxHealth*100.
* Where COB uses ''SetMaxReloadTime'', Lua uses ''GetMaxReloadTime''.
* Where COB uses ''QueryLandingPadCount'' and ''QueryLandingPad'', Lua uses ''QueryLandingPad'''s'''''
* The x and z arguments to ''HitByWeapon'', ''HitByWeaponId'' and ''RockUnit'' are given in (x, z) order in Lua, and the opposite order in COB.
* ''BeginTransport'' and ''EndTransport'' take the height of the unit in COB and the unitID in Lua. (Use 'local height = Spring.GetUnitHeight(unitID)' to get the height.)
* ''TransportDrop'' gets PACKXZ(x,z) in COB; in Lua, it gets the entire vector (x, y, z) as three arguments.
* Where COB uses ''SetSpeed'' and ''SetDirection'', Lua uses ''WindChanged'' and ''ExtractionRateChanged''.
* Lua does not have ''Go'' (this is called for activated extractors immediately after each ''SetSpeed'' call.)
