Struct canrust::canvas::Polygon

pub struct Polygon { /* fields omitted */ }

An abstraction over SFMLs ConvexShape

Implementations

impl Polygon

pub fn new(points: Vec<(f32, f32)>) -> Option<Self>

Creates a shape from a vector of coordinates

pub fn from_polygon(polygon: &Polygon) -> Option<Self>

Creates a new shape with the same points and settings

impl Polygon

pub fn set_fill_color(&mut self, color: Color) -> Result<(), String>

Sets object fill color.

pub fn set_outline_color(&mut self, color: Color) -> Result<(), String>

Set objects outline color

pub fn set_outline_thickness(&mut self, size: f32) -> Result<(), String>

Set objects outline thickness

pub fn set_point_count(&mut self, pc: u32) -> Result<(), String>

Set objects point count. For example if point count is 3, we get an equilateral triangle.

pub fn set_origin(&mut self, origin: (f32, f32)) -> Result<(), String>

Sets shapes origin point(by default its the top left corner, or objects 0, 0 coordinates). This is the point, around which objects rotate and which will be used to set objects position.

If if you have a Rectangle with the default origin point which is 0, 0 on position x = 320 and y = 180 and width and height of 80 and 100 pixels, valid origin points are coordinates x+width and y + height.

pub fn set_rotation(&mut self, angle: f32) -> Result<(), String>

Sets the rotation of the object

pub fn rotate(&mut self, angle: f32) -> Result<(), String>

Adds to objects existing rotation

pub fn set_position(&mut self, position: (f32, f32)) -> Result<(), String>

Sets objects position on Canvas

pub fn get_fill_color(&self) -> Option<Color>

Returns fill color of the object

pub fn get_outline_color(&self) -> Option<Color>

Return the outline color of the object

pub fn get_outline_thickness(&self) -> Option<f32>

Returns the outline thickness of the object

pub fn get_position(&self) -> Option<(f32, f32)>

Returns objects position on the Canvas

pub fn get_rotation(&self) -> Option<f32>

Returns the angle at which the object is rotated.

pub fn get_origin(&self) -> Option<(f32, f32)>

Returns the objects origin point.

pub fn get_point_count(&self) -> Option<u32>

Returns objects point count
