Question

An AI assistant wrote this Godot 4 GDScript for a cooldown-based dash ability. Players on low-end phones (low FPS) report the dash sometimes triggers twice or the cooldown counts down faster than the on-screen timer. Review the code and find the delta-time / sampling bug.

gdscript

1func _process(delta):2    if Input.is_action_pressed("dash") and cooldown <= 0:3        velocity = facing * DASH_SPEED4        cooldown = DASH_COOLDOWN5    cooldown -= 1   # tick the cooldown down one per frame6    move_and_slide()

What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
