The document AoS Entity Memory Format said that byte 0x5C "InitializeEnemyFromDNA sets this to 0x12".
I changed this value of an enemy several times and find the enemy is hidding behind the layer when the number is larger than the Z-index of the layer. And this is also effecitive when I change the byte 5C of other Entities such as fire or candle, It can go behide the layer, or cover other Entities with a larger number in their byte 0x5C as expected.
So I think this value is the Z-index of the entity.
