🔧 Devlog #29 – GASP 5.5 + ALS Integration: Precision Aim, Reload Slot Magic & Arrow Quiver Setup
In this two-hour live build I push the third-person shooter prototype several steps closer to “feel-right” gameplay:
🔧 What we tackled
Upper-body reload system
Created a dedicated Reload slot, layered it above the ALS overlay, added modify-curve logic & inertial blending for perfectly-smooth pistol/bow reloads.
Camera-driven precision aiming
Replaced muzzle-socket traces with a forward-vector trace from the camera for cross-hair-perfect hits.
Debugged with dual coloured traces to compare old vs new logic.
Custom quiver (arrow pocket)
Imported a free Sketchfab asset ➜ re-scaled, re-pivoted in Blender, built collision & attached to the spine socket.
Added 5 skeletal-mesh arrow props, each on its own socket, ready for runtime depletion.
Animation-blend troubleshooting
Explained modify-curve workflow, dead-blend vs inertialization, and why reload montages were “snapping” while sprinting – then fixed it live.
Next steps
Cross-hair widget tied to new trace, ammo-refill logic, and camera-offset polish.
