Libraries.Game.Collision.Shapes.Polygon

This class extends the CollisionShape2D by rewritting specific actions that are blueprint actions in CollisionShape2D for the shape of a polygon. This class records all of the geometric properties that a polygon should have. To display the polygon with the properties that you've set, you have to use "Libraries.Game.Graphics.Drawable".

This action returns the centroid of the polygon in the global coordinates.

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

This action computes the area of the polygon based on the geometry of the polygon that is stored inside this Polygon class.

This action calculates the BoundingBox2D for the polygon shape.

This action finds the centroid of the polygon based on the geometry of the polygon.

This action finds the closest distance between the point of interest and the polygon.

This action finds ths mass and mass rotational of inertia of the polygon based on the density of the polygon passed in and the geometry of the polygon.

This action sets another polygon shape using the current polygon shape.

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

This action returns the centroid of the polygon in the local coordinates of that polygon.

Because each polygon can be seen as an primitive shape, therefore, a polygon is its own child and parent.

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action returns all of the normals to the edges of the current polygon.

This action returns the radius of the shape.

This action gets the type of the shape that is used to collide with another 2D shape.

This action gets the point at which the vertex of interest is at.

This action returns how many vertices the polygon has.

This action returns all of the vertices of the current polygon.

This action returns whether the polygon is a box or not.

This action shrinks or expands the polygon shape.

This action records the passed vertices to this class and also calculate the normal vectors to the edges from the polygon created using the vertices passed.

This action sets the polygon shape to an untilted box centered at the origin.

This action creates a polygon as a rectangle with present center point and tilted angle.

This action sets the radius of the shape.

This action sets the type of the shape that will be used to collide with another 2D shape.

This action checks whether the polygon is convex.
