peek() [2/2] template<typename FirstValueType, typename... RemainingValueTypes> auto peek ( uint32_t target_frame ) const -> tween_value_t nodiscard Queries the interpolated value at any frame without changing state. Previews what the value would be at the target frame without moving the tween. Useful for scrubbing, previewing, or inspecting the animation curve. Does not trigger events. Parameters target_frame Frame to query (clamped to valid range) Returns Interpolated value at the target frame auto t = tweeny::from(0).to(100).during(100U).build(); auto midpoint = t.peek(50U); // Preview value at frame 50 (returns 50) auto start = t.peek(0U); // Preview start value (returns 0) // Tween still at frame 0, not moved
