# Objective - Fixes #17642 ## Solution - Implemented method `new_bezier(points: [P; 4]) -> Self` for `CubicSegment<P>` - Old implementation of `new_bezier` is now `new_bezier_easing(p1: impl Into<Vec2>, p2: impl Into<Vec2>) -> Self` (**breaking change**) - ~~added method `new_bezier_with_anchor`, which can make a bezier curve between two points with one control anchor~~ - added methods `iter_positions`, `iter_velocities`, `iter_accelerations`, the same as in `CubicCurve` (**copied code, potentially can be reduced)** - bezier creation logic is moved from `CubicCurve` to `CubicSegment`, removing the unneeded allocation ## Testing - Did you test these changes? If so, how? - Run tests inside `crates/bevy_math/` - Tested the functionality in my project - Are there any parts that need more testing? - Did not run `cargo test` on the whole bevy directory because of OOM - Performance improvements are expected when creating `CubicCurve` with `new_bezier` and `new_bezier_easing`, but not tested - How can other people (reviewers) test your changes? Is there anything specific they need to know? - Use in any code that works created `CubicCurve::new_bezier` - If relevant, what platforms did you test these changes on, and are there any important ones you can't test? - I don't think relevant --- ## Showcase ```rust // Imagine a car goes towards a local target // Create a simple `CubicSegment`, without using heap let planned_path = CubicSegment::new_bezier([ car_pos, car_pos + car_dir * turn_radius, target_point - target_dir * turn_radius, target_point, ]); // Check if the planned path itersect other entities for pos in planned_path.iter_positions(8) { // do some collision checks } ``` ## Migration Guide > This section is optional. If there are no breaking changes, you can delete this section. - Replace `CubicCurve::new_bezier` with `CubicCurve::new_bezier_easing` |
