Quick answer: PS5 DualSense adaptive triggers staying soft despite SetTriggerEffect calls? Wrong pad index, mode mismatch, or the effect was overwritten by a later call without sustaining.

A gun firing should engage Trigger Continuous resistance. The code calls SetTriggerEffect once and the next frame’s SetVibration call inadvertently clears it.

Per-Frame State

DualSense state isn’t persistent — the controller stays at the last sent state until a new one arrives. Send your desired trigger state each frame, especially during interactive moments.

Correct Mode Constants

The trigger effect struct’s mode field accepts CONTINUOUS, FEEDBACK, WEAPON, etc. Each has a specific parameter layout. Match per Sony docs.

Pad Index Matches Controller

Multi-controller scenarios: the pad index is the slot, not the user ID. Tracking the right slot prevents sending effects to the wrong pad.

Combine With Vibration

Trigger effects and rumble are independent. Setting one doesn’t reset the other. But some helper APIs reset both — check your wrapper’s behavior.

Verifying

Triggers exhibit the configured resistance during gameplay. Each gun has its own feel; release resets to soft.

“DualSense state is per-frame. Send trigger effects every frame they should hold.”

Document the per-game DualSense feel in design docs — trigger feedback is one of the touches players remember from PS5 ports.
