Feedback ownership pattern

Use one state-to-feedback renderer:

feedback-ownership-pattern.gpc

int mode;
int feedback_dirty = TRUE;

main {
    if(event_press(PS5_TRIANGLE)) {
        mode = mode + 1;
        if(mode > 2) mode = 0;
        feedback_dirty = TRUE;
    }

    if(feedback_dirty) {
        update_feedback();
        feedback_dirty = FALSE;
    }
}

function update_feedback() {
    if(mode == 0) set_ps4_lbar(0, 0, 32);
    else if(mode == 1) set_ps4_lbar(0, 32, 0);
    else set_ps4_lbar(32, 0, 0);
    return 0;
}

Render on state change, not blindly every cycle. On mode exit, reset any LED, rumble, trigger, or output override that should return to console ownership.
