You should add a small tolerance, because a) MapAndreas isn't 100% precise and b) the player position will always be above the ground (exactly 1 unit above ground, which is the origin of the player model).

For example

Код:

if(floatabs(z - 1.0 - mz) < 0.3) // Player position must be between 0.7 and 1.3 meters above ground position (considering MapAndreas isn't precise) - a tolerance of 0.3m - subtract 1.0 from player position for the offset
{
 // Not midair
}

Still velocity is a valid way to do so. There's no way a player has a velocity of 0.0 (or similarly low) if midair, except being frozen or modding. But even then it's extremely unlikely to still have a standing/crouching animation.
MapAndreas will detect anything obstructed as underground. You could work with a combination of velocity, animation and player state to get a better result.
