VIDEO PREVIEW

Spline Path System – Movement Framework is a Blueprint-only spline-locked movement solution for “rail / guided path” gameplay with optional junction switching and room transitions.

Key Features

• Spline-Locked Movement (No Drift): player movement is strictly constrained to the active spline.

• Single-Axis Input: movement uses only one axis (forward/back) while on spline.

• Junction Switching: show an interaction prompt and press E to switch to an alternate spline at junctions.

• Room Transition Mode: exit spline mode and restore full WASD movement inside “Room” areas.

• Optional Camera Blends: smoothly blend to a new camera when entering a room (if configured).

• Blueprint-Only: no C++, easy to integrate.

How It Works

• Enter spline mode via BP_SplineSwitchTrigger.

• While on spline, movement is locked to the path (no sideways movement).

• At junction triggers, a prompt appears: “Press E to switch path”.

• At end triggers, you can either exit spline mode or transition into a room (full WASD).

Controls / Input

SPLINE MOVEMENT (LOCKED)

• Movement is strictly constrained to the spline (no sideways drift).

• Axis mapping depends on SwitchSpline:

  • SwitchSpline = False — driven by X

  • SwitchSpline = True — driven by Y

• Enter the path via BP_SplineSwitchTrigger.

ROOM MODE (UNLOCKED WASD)

• EndPath can be configured as a room transition (CanGoToRoom = True).

• Exits spline mode and restores full WASD movement.

• Optional: if NewCamera is set, the view blends to that camera on enter.

• Return to spline via BP_SplineSwitchTrigger.

Included

• Blueprint actors: Spline switch triggers / junction triggers / end triggers

• Example level setup (recommended)

• Basic UI prompt widget (switch path)

Notes

Designed for quick integration: place splines + triggers, assign references, play.
