Getting Started

Auto Aim Component is a Blueprint asset package. Migrate the core assets from the product project, add the component to your player, and implement the target interface on NPCs.

Migrate the assets

1. Open the Auto Aim Component project from FAB.
2. In the Content Browser, go to Content → AutoAimComponent → Blueprints → Main.
3. Select these three assets (Ctrl+click):
   • AutoAimComponent
   • BPI_AutoAim
   • CT_DistanceBasedAngle
4. Right-click → Asset Actions → Migrate.
5. Choose your project’s Content folder and confirm.

Note

CT_DistanceBasedAngle is only required when Use Distance Angle Check is enabled on the component. Migrating all three keeps the package complete.

Add the component to your player

1. Open your player character Blueprint.
2. Add Component → Auto Aim Component.
3. Review component settings in the Details panel.

Demo defaults (from the component CDO): Trace Distance 3000, Trace Size 100, Interp Speed 10, Use Smooth Aiming on, Types To Trace = Pawns.

The example FirstPersonCharacter drives the component from InputActionStartTargeting (press = Start Trace, release = End Trace).

Make targets aimable (BPI_AutoAim)

Enemy actors must implement BPI_AutoAim:

1. Open your target Character Blueprint.
2. Class Settings → Interfaces → Add → BPI_AutoAim.
3. Implement Get Skeletal Mesh Component — return the character Mesh component.

See ThirdPersonCharacter_NPC in the product project for the reference implementation.
