Schematic to place around entity

plz help me :,(

@#2 Ive done that but then I shoot the gun, and it places the schematic right in front of me, and it also can be placed in the air so I was wondering if there was a way to do so without that happening, or is there a simpler way like when I shoot the gun, the enemy becomes encased in ice?

@#3 how would i edit the source code to do this?

@#3.1.1 

package mod.mcreator;//based on master condiguration

@#5 do you think you could also help me figure out how to add a custom armor model?

@#4 Also the code didn't work sadly
