 **Character** colliders are used for player and script-controlled characters such as NPCs. Entities with [character components](xref:Stride.Physics.CharacterComponent) can only be moved with [SetVelocity](xref:Stride.Physics.CharacterComponent.SetVelocity\(Stride.Core.Mathematics.Vector3\)), [Jump](xref:Stride.Physics.CharacterComponent.Jump), and [Teleport](xref:Stride.Physics.CharacterComponent.Teleport\(Stride.Core.Mathematics.Vector3\)).

 Stride simulates real-world physics such as gravity and collisions. This section explains how physics components work, how to add them to your project, and how to use them with scripts.
