Do the following behaviours / abilities exist

[acoustic elbow]

my son wants the following "abilities" for our custom entity in Bedrock

1. it has to be deflect projectiles (specifically arrows/bolts but i suppose all projectiles)
2. it's attack animation should "shoot blocks", so i'm thinking a fireball animation but convert the fireball into a stone-shaped object
3. change facial expression (texture) upon being attacked... not sure how to approach this

yes they exist

3 is possible since minecraft has a query system that can detect the properties of an entity like if they’re moving, attacking, and more if you add more entity components to it
