# KS.Reactor.Server

### Namespaces

[KS.Reactor.Server.PhysX](/reactor/api-reference/ks.reactor.server.physx.md)

### Classes

[ksServerEvents.PlayerSpawnEntity](/reactor/api-reference/ks.reactor.server/ks.reactor.server.ksserverevents/ks.reactor.server.ksserverevents.playerspawnentity.md)

Contains a event for validating a player request to spawn an entity, and a event that fire when a player spawns an entity.

[ksBaseRigidBody](/reactor/api-reference/ks.reactor.server/ks.reactor.server.ksbaserigidbody.md)

The base class for PhysX rigid bodies. When derived scripts are attached to entities, it allows the entity to be controlled by the physics simulation with its properties such as mass, drag, and velocity. If isKinematic is enabled, forces, collisions or joints will not affect the rigidbody, but it will push regular dynamic actors out of the way when moved.

If isKinematic is enabled, forces, collisions or joints will not affect the rigidbody, but it will push regular dynamic actors out of the way when moved.

[ksRigidBody2DView](/reactor/api-reference/ks.reactor.server/ks.reactor.server.ksrigidbody2dview.md)
