Set objects invincible ?

[JG13Wulf]

Hello

 

I made some anti-straffing shelter for AAA.

Those protect AAA from low level attack and allow enemy planes to have some protection when trying make low level attack.

 

 

But as my shelter are made with weak objects, AAA blow them up by trying to shoot low enemy planes. Only a few shoot are stopped. Then AAA is able to shoot just over the tree.

Is it possible to set those object to non destructible ?

 

Thanks.
