/// Script issues: ///
//////////////////////

// We need to either re-arrange the living/dead/death logic, or add another animation phase.
// May as well set up the Vaus explosion and add it with a SPARKLE LWeapon.



//# QUEST ISSUE: Bricks Break playing the wrong sound, despite being set. Might be a 2.54 bug? -Z

/* ZC issues:
    Continue script does not run when Init script runs. It NEEDS to do that! Otherwise, settings that affect things such as Link's tile
    don't happen before the opening wipe.

/// Changes, Revision History
///
///
/// Alpha 0.16: Reverted Alpha 0.15 changes back to before adding any angular physics.
///     Then, re-implemented ONLY the Vaus midpoint physics.
///     Fixed the hack for UID in brick.take_hit(). This means that ZC 2.54 Alpha **32** is now the minimum ZC version.

FIXED in Alpha 32
I forgot to expand ->Misc[] in sprite.cpp, which should be fixed int he source for Alpha 32.
    This meant that r/w to ptr->Misc[>15] would use invalid data, or overwrite other data. bad, bad, bad.

    FIXED in Alpha 32
    //Note: We also need to store the UID of each ball, as HitBy[] works from the UID, not the pointer.
