This article discusses how rotation values are applied to AxisAlignedRectangles. ### AxisAlignment and the collision/visible representation of an AxisAlignedRectangle As far as the visible representation and collision behavior of an AxisAlignedRectangle, rotation will have no impact on an AxisAlignedRectangle. For more information, see [this section](https://github.com/flatredball/FlatRedBallDocs/tree/main/frb/docs/index.php#What_does_.22axis_aligned.22_mean.3F). ### How do children of AxisAlignedRectangles behave? All positions in FlatRedBall are defined by a combination of X, Y, and Z values. These values, when measuring absolute space, represent the distance from the origin along each axis by the same name as the component (X axis, Y axis, and Z axis). In FlatRedBall, when using an unrotated [Camera](https://github.com/flatredball/FlatRedBallDocs/tree/main/frb/docs/index.php), positive X points to the right and positive Y points up. The "axis aligned" part of AxisAlignedRectangles simply means that the edges of the rectangle are parallel (line up with) the X and Y axes. This is always true for AxisAlignedRectangles - even if they are rotated. However, that doesn't mean that the underling rotation values are always 0. In other words, if another [PositionedObject](https://github.com/flatredball/FlatRedBallDocs/tree/main/frb/docs/index.php) is attached to an AxisAlignedRectangle, and the (parent) AxisAlignedRectangle is rotated, then the child [PositionedObject](https://github.com/flatredball/FlatRedBallDocs/tree/main/frb/docs/index.php) will react to the rotation. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.flatredball.com/flatredball/api/flatredball/math/geometry/axisalignedrectangle/axis-alignment-and-rotation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
