Projectile goes through players. Interplayers collision

Hi guys. So i have a player, equiped with an ability to cast a projectile (mesh ball). When shooting with this ball into the physics objects or meshes , it triggers impactEvent and the projectile destroys. But when shooting into other player, the projectile just goes through him. Is there some flag i am missing, or how can i make the projectile impact the player? Also, not to create a separete topic and spam, is there a simple way to enable player collisions, so they can not go through each other?

It's likely because you don't have any team settings setup so all players are considered friendly.

omg, thank you! I dont know how i missed that...
