Libraries.Game.Collision.Shapes.Circle

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

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 calculates the area of the circle.

returns the distance of the point relative to the outside edges of the circ

if the length()^2 <= radius^2, then that means that vector lies inside the circ

This action calculates the mass of the circle. The action assumes that the density of the circle is constant at every point on the circle, therefore, the center of mass of the circle is just at the center of the circle.

This action creates a copy of another circle shape using the properties of the current circle properties.

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)

Because a circle is a primitive shape, therefore, it is its own child (think of it as a circle makes up a circle).

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action returns the radius of the shape.

This action returns the centroid of the circle relative to the circle's local coordinates.

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

This action returns the centroid of the circle relative to the circle's local coordinates.

This action returns 1 for a circle.

Because we don't want to change a circle into an oval shape, so this action will use the first number that you passed in to change the size of the circle so that the circle will still be a circle after the change.

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 tests if a point of interest is inside the circular shape.
