hey guys i have made a cillinder arround the first person player attached to its graphics capsulle the sillindeer arround the player is invisseble i removed its also got a damage reciever thats works but hen my ennemies shoot at me my shield(cillinder) will get damaged but the player also so the point is ehen my ennemies shoot trough my shield and hits my player the sield shoud prevent that from happening

i would like it to be one way from inside. so i can shoot from the inside and i cant be hit untill my shield is dead afther 200 hits

Does the collision with your shield destroy the bullet?
