Advanced Ledge System on Unreal Engine 5 Only Blueprints - Part 11
We finish the ledge climb-up feature in Blueprints: bind T, space-check with a capsule matching the player, choose the correct montage, and move the character with clean timelines. You’ll see where to stop timelines, how to gate inputs during the move, and simple tweaks (blend times, offsets) that make it feel AAA.
Most Valuable Lessons and Insights
Make sure the space check matches your character: run a Multi Capsule Trace using the character’s Capsule Radius and Half Height; use a small forward step and a Z offset near 110 so the trace actually hits the landing surface.
Make sure to stop conflicting motion: before playing the climb-up montage, stop all ledge timelines (movement, hang rotation/position) to avoid overlap and snapping.
Make sure players can’t break the animation: gate controls with a can process input boolean during the montage, then restore it on blend out so camera look still works while inputs are blocked.
Make sure montage timing is clean: add an Anim Notify (On Notify Begin) to drive state changes instead of plain delays, and set a short blend out on the previous montage to smooth into climb-up.
Make sure you finish planted: adjust the final landing offset; in this build, setting the vertical placement around 105 felt correctly grounded.
