Set the health value and holes from bullets in the Health section. Blood holes will be generated on enemies if a character shoots them.
Press the Generate Body Colliders button to create colliders, and then set Damage Multipliers. These colliders and multipliers will be used to get damage from characters. Also, colliders will be used like a ragdoll after the enemy's death.
Since colliders саn't be created automatically for non-humanoid characters, you should add them manually.
Create a few colliders on different parts of the body, place them in the script, and set Damage Multipliers. Also, create a ragdoll and set it in the appropriate variable in the script.
